Zlob.zipcodec is a suspicious AV detection that may be a sign of a Trojan infection
Zlob.zipcodec is a generic name that can be a false positive , software problem or denote a highly dangerous Trojan Zlob infection.
Many people reported the issue on different cybersecurity-related forums and point to the Spybot as a culprit. The zlob zipcodec detection normally indicates that the AV engine detected and terminated a malicious or potentially dangerous activity on the system.
AV programs contain a database of behavioral scrips that are used to scan files on the system. If a program or file exhibits suspicious, unusual, or dangerous traits, security software blocks it. However, commonly security programs run into software incompatibilities or lack virus definitions, thus leading to false positives.
Zlob.zipcodec.exe is the initial detection by Spybot. According to users , when running Spybot Search and Destroy, the scan freezes upon detection of the mentioned executable file. The security program can neither be stopped, not closed, thus users have to terminate its task via Task Manager or reboot the system completely.
Spybot has been dealing with the issue for some time and explained that the software had a bug, which damaged the file leading to Zlob.zipcodec detection. The issue has been fixed in 2016, though many people are asking how to remove zlob.zipcodec up till now. Therefore, it can be presumed that this name might have been misused for malicious activities, namely Trojan known as Zlob.
How to remove zlob.zipcodec virus appears to be the most common question in security-related forums. Most of the entries contain the mentioned file, which triggers continuous failures of AV scans. However, the same file is said to appear interchangeably with the following AV detections:
In this case, an immediate scan with a professional anti-virus program is required to terminate Zlob Trojan or another dangerous virus that belongs to this family. This infection is one of the oldest cyber infections, which is infamous for malicious activities, such as data harvesting and downloading of other viruses.
Zlob zipcodec removal should solve the problem with freezes, slowdowns, and similar system malfunctioning. Even more, the elimination of this infection is the only way to prevent the loss of personal information or identity theft. Trojans are extremely dangerous and persistent in removal. Initially, the virus initiates multiple system changes within registries and processes at boot, thus weakening the system's security.
If the system is infected with zlob.zipcodec Trojan, it may open the backdoor to other infections, such as malware or ransomware. Connecting to remote control servers, it may download malicious executables in the background, consume CPU, contaminate the system with advertising material and lead to various security issues.
There is no way to remove zlob.zipcodec from Windows without a professional anti-virus program. You can run a scan while in Safe Mode as explained at the end of this article. Nevertheless, the elimination process can hardly fix the damage that the virus might have caused.
Before you remove zlob.zipcodec virus or related files and software, try to find out if it's a virus, false-positive detection or AV bug. Download an alternative security program, for example or , and set it to run a full system scan.

AV freezes during the scan is often a sign of a Trojan
Regular system scans with the anti-malware program should become every user's routine.
This way, the system will be protected from dangerous viruses and malware. However, if the scan is disrupted or freezes upon finding a suspicious file, it may be a sign of a Trojan or another dangerous virus.
Malicious software often contains files that can block anti-virus, thus preventing removal and ensuring a longer period for data stealing, malware download, keylogging, and other activities. The only way to terminate such viruses is to restart the system into Safe Mode with Networking because this environment is programmed to terminate all processes that are unnecessary for the system's performance.
You should also be very conscious when browsing the web to protect yourself from malicious infections. Trojans, ransowmare, spyware, and similar entries can be installed on the system after clicking on online ads positioned on rogue websites. Besides, do not rely on pirated software, cracks, or keygens as they are a perfect medium to execute malicious files.
Last, but not least, do not underestimate the danger of spam emails. Criminals are really professional in terms of mimicking reputable companies, such as FedEx, Red Cross, SBA, and many others. Rogue emails typically contain a relevant topic and the body text may also be convincing.
However, if the message contains an attachment, we highly recommend double-checking the sender, looking for mistakes, or other suspicious indications that may sign a fraud. Anyway, it is possible to scan e-mail attachments before opening them because one reckless click can lead to a virus attack.

More from our earlier report on Zlob.zipcodec
- Zlob.zipcodec removal may be disrupted by malicious Trojan entries.
- Thus rebooting into Safe Mode with Networking may be required to run a scan
How to check the PC for Zlob.zipcodec
- File:
zipcodec.exe
How to remove Zlob.zipcodec
A loader's job is to install other malware, so treat the PC as infected with more than one program until the scans are clean.
Step 1: Check where zipcodec.exe runs from and stop it
In Task Manager (Ctrl + Shift + Esc) find
zipcodec.exeon Processes, right-click it and choose Open file location before ending anything.Windows' own files live in
C:\Windows\System32; the same name in%AppData%, %Temp% or C:\Users\Public is an impostor. If the folder is wrong, right-click the process again, choose End task and delete the file.If it starts again within seconds, a task or another process restarts it, so run the scan step in Safe Mode. Task Manager works the same in Windows 11 and Windows 10.
Full procedure with screenshots: Close a frozen app (Task Manager, Force Quit) On uGetFix
Step 2: Delete scheduled tasks that bring it back
Programs like Zlob.zipcodec add a scheduled task so they return after an uninstall or reopen a page at every sign-in. Start Task Scheduler, open Task Scheduler Library and sort by Last Run Time to see what ran recently.
On the Actions tab, a program in a user folder, a script or a web address is a warning sign; right-click such a task and choose Delete.
Tasks with names copying Google, Edge or Windows updaters but pointing to an odd folder are typical. The tool looks the same in Windows 11 and Windows 10.
Windows 11: Task Scheduler Library, the task selected, the Actions tab shows the file it runs. Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 3: Remove it from startup
Press Ctrl + Shift + Esc to open Task Manager and select Startup apps (Windows 11) or the Startup tab (Windows 10). Disable entries you do not recognise, especially ones with no publisher or with a name that copies a Windows component.
Right-click an entry and choose Open file location to see where it runs from: programs in
%AppData%or%Temp%deserve a closer look. Some entries are not listed there but in the registry Run keys, which the procedure below shows how to check.Full procedure with screenshots: Stop apps from opening at startup On uGetFix
Step 4: Delete the folders left behind
Uninstalling often leaves the program's folders, and some threats reinstall themselves from them.
Press Windows + R, type
%LocalAppData%and press Enter, then do the same for%AppData%and %ProgramData%, and look for folders named after Zlob.zipcodec, its publisher or created on the day the problem started. Delete those folders, and check C:\Program Files and C:\Program Files (x86) too.If Windows says a file is in use, end it in Task Manager or delete the folder after a restart in Safe Mode. The folders are the same in Windows 11 and Windows 10.

Step 5: Scan the PC, then run the offline scan
A scan finds the parts of Zlob.zipcodec that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.
Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.
It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 6: Change passwords from another device and sign out other sessions
Zlob.zipcodec can copy saved passwords, cookies and session tokens and send them out in seconds, so cleaning the PC does not undo the theft.
Change your passwords on a device that was never infected, starting with the e-mail account, since every other reset goes through it. On each account, end all other sessions and check the recovery e-mail, phone number and forwarding rules.
Then turn on two-step verification. Sign in on the Windows 11 or Windows 10 PC again only after the offline scan is clean.

Manual removal using Safe Mode
Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. - it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.
Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.
- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.
- Go back to the process, right-click and pick End Task.
- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.
Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.
- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
Downloads
Recycle Bin
Temporary files - Pick Clean up system files.
- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
After you are finished, reboot the PC in normal mode.

Fix problems by eliminating zlob.zipcodec and related malware
Zlob.zipcodec freezes may be a software-related problem, but can also point to a breached system's security.
Before getting scared, evaluate the possibility that your system may be running an outdated Spybot version, which has a bug causing scan freezes and another malfunctioning. In this case, you can navigate to this website and download an installer provided by Spybot developers to fix the bug.
If, however, the issue is not related to Spybot, but another AV engine that flags the Zlob.zipcodec.exe as a malicious entry, reach accordingly. First of all, try to finish the AV scan and set the program to remove all malicious entries.
Zlob.zipcodec removal may require disabling multiple procedures and changing back the settings of the computer. Thus, there is no way to eliminate it manually without the help of an automatic tool. Also, do not leave the system damaged. Trojans are capable of affecting various settings and functions of the PC, so a full repair is required.
[GI=method-1]If you cannot remove zlob.zipcodec because it is protected by malicious entries, the only way to get rid of it is to launch AV scanner while in Safe Mode with networking.
After removal: passwords, accounts and prevention
Secure your accounts after the clean-up
Assume that whatever was saved in the browsers on this PC while the PC showed an unfamiliar process called zipcodec.exe in Task Manager has been copied:
- passwords
- cookies
- autofill data
Work from a clean device, or from this PC once the offline scan finds nothing.
Start with your main e-mail account, because it can reset everything else, then banking and payment, then social and gaming accounts. Change each password, sign out of all sessions and turn on two-step verification: Turn on two-step verification / secure a hacked account.
The full order, including crypto wallets and card replacement, is in securing your accounts after malware.
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.
One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.
However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable.
Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:
- power cuts
- Blue Screen of Death errors
- hardware failures
- crypto-malware attack
- even accidental deletion
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.
Questions about Zlob.zipcodec
What is zipcodec.exe and why is it running?
Every process is started by something:
- a program you installed
- a Windows service
- a scheduled task
- a startup entry
To learn why zipcodec.exe runs, find its file with Open file location in Task Manager, then look for an entry pointing to that file in Settings > Apps > Startup and in Task Scheduler.
Sort Installed apps by date to see what arrived when the process first appeared. Once you know the owner, you can decide whether to keep it, switch it off at startup or uninstall it completely.
Can I delete the zipcodec.exe file?
Only after you know what it belongs to. If zipcodec.exe is part of a program, uninstall that program through Settings instead, so its services and tasks go too. If it belongs to nothing and is unsigned, end the process, disable whatever starts it and then delete its folder.
Do not delete files from the Windows folder or files signed by Microsoft: those are part of the system, and removing them can stop Windows from starting. When in doubt, run a Microsoft Defender scan first and let it decide.
Is zipcodec.exe a virus?
If it sits outside the Windows and Program Files folders and your antivirus links it to Zlob.zipcodec, yes. zipcodec.exe is the file name used by this trojan. Some trojans borrow the names of real Windows components, so the name alone does not decide it:
- right-click the process in Task Manager
- choose Open file location
- look at the folder and the publisher under Properties > Details
A file in a user folder with no publisher is the trojan. Do not delete it by hand while it runs; use the offline scan in the plan above.
Should I report Zlob.zipcodec?
Report it if you lost money, if accounts were taken over, if you are a business, or if the trojan came through a scam call. A police or national cybercrime report gives you a reference number for your bank and insurer and helps link cases.
You do not need to report a trojan that antivirus blocked before it ran. Before reporting, write down the dates, the detection name, file names and any messages or transactions linked to the attack; screenshots of antivirus alerts are useful evidence. The country list is in the report section above.
How do I know if my PC has Zlob.zipcodec?
Often you do not, which is the point of a trojan. Possible signs are an antivirus alert naming Zlob.zipcodec or a generic trojan detection, unknown programs or scheduled tasks, processes with random names in Task Manager, browser extensions you did not add, security settings turned off, slower performance, or account alerts about logins from unknown places.
The reliable check is a full scan followed by Microsoft Defender's offline scan. If you recently ran a crack, a fake installer or a command a website told you to paste, scan even without symptoms.
My antivirus was on. How did a trojan get past it?
Antivirus programs see a file only when it is written or run, and criminals test each new build against popular scanners before release. Detection catches up within hours or days, which is often after the first victims ran it.
Archives with passwords, installers that fetch the malware later, and scripts run through PowerShell make the job harder. That is why behaviour such as downloading cracks or pasting commands matters more than any setting. Keep Windows and Defender updated, and turn on Reputation-based protection in App & browser control.
Should I check my other computers too?
Yes, it takes little time and removes doubt. Zlob.zipcodec itself usually stays on one PC, but the download that carried it may have been copied to other computers, shared drives may hold the same installer, and an attacker who had access could have tried saved passwords on other devices.
Run a full scan on every Windows PC in the home or office, check shared folders for the original download, and change Wi-Fi and router passwords if they were stored on the infected machine.
Is Zlob.zipcodec a known trojan?
Not as a documented family, at least not yet. What is known is the visible sign, an unfamiliar process called zipcodec.exe in Task Manager, which matches a hidden program working for someone else.
New threats are often seen by victims weeks before researchers publish anything about them. Treat Zlob.zipcodec as you would any trojan:
- remove what starts it
- run an offline scan
- change passwords from another device
If a scan reports a detection name, keep it; it usually reveals the family and whether it is known to download other malware. We update this guide when an analysis appears.
Is it safe to do online banking after seeing an unfamiliar process called zipcodec.exe in Task Manager?
Not on that PC until it is clean. A program that produces an unfamiliar process called zipcodec.exe in Task Manager runs with your rights and could read what you type or what the browser shows. Use a phone or another computer for banking and for changing passwords.
When the offline scan of the affected PC is clean and nothing suspicious starts with Windows any more, you can go back to using it. Check your bank statements for the past weeks either way, and call the bank if anything looks unfamiliar; banks can block cards and reset access quickly.
Will Fortect remove Zlob.zipcodec?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Zlob.zipcodec, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
