What Trojan-spy.win32.agent.gen can steal or download
From our report of Jun 2018 · not reviewed since
Trojan-spy.win32.agent is a generic name that describes a group of dangerous trojan horses that can perform malicious activities on the affected computer.
Such cyber threats can sneak into machines unnoticed, can hide deep in the system and do harmful activities in the background. Trojan horses might be capable of stealing personal information, such as passwords/logins, banking or credit card information. Additionally, they might be used for malware, ransomware or spyware installation.
Trojan-spy.win32.agent.gen virus is one of the variants of a huge group of trojan horses called Win32/Agent. Nevertheless, authors of such cyber threats try to create malware that can avoid detection; the major security vendors can still identify them. Among the most popular detections are these three versions of the trojan:
Trojan horses that belong to the same family share similar functionality. However, they contain some specific features and are created for different reasons. Some of the viruses are created for stealing information, and others are used for opening a backdoor for other cyber threats. Trojan-spy.win32.agent.gen might be used for the following reasons:
In order to perform these and many other activities, Trojan-spy.win32.agent needs to find its way to get into the system. However, these cyber threats cannot get into the machine without user's participation. Usually, developers of malware trick people into downloading obfuscated programs or updates. Also, trojan might spread via malicious spam emails or ads.
Once it gets into the computer, malware immediately makes system changes. Usually, it modifies Windows registry, deletes or creates new registry keys in order to boot on startup or disable computer's protection. Due to these changes, the affected machine becomes sluggish, programs unresponsive and countless system error messages might pop on the screen as well.
Some versions of Trojan-spy.win32.agent might also disturb browsing activities by displaying aggressive ads and preventing from accessing security-related websites. The latter trick helps malware to remain on the system longer because users are unable to install needed tools for the elimination.
However, Trojan-spy.win32.agent.gen removal has to be completed despite resistant trojan's behavior. For this task, you will need to install anti-malware program and scan the affected machine. In order to do so, you may need to boot the computer to Safe Mode with Networking. This helps to disable the virus and complete automatic elimination with or other reputable software.
Please do not try to remove Trojan-spy.win32.agent.gen manually. It's nearly impossible to clean all malicious files and programs from the machine. Trojan horses are complex cyber threats and might bring other malware to the system. So, you should rely on powerful anti-malware tools to make the system safe again.

How Trojan-spy.win32.agent.gen got on your PC
From our report of Jun 2018 · not reviewed since
The name "trojan horse" itself reveals the main way how these malicious programs spread.
They look like safe and legitimate files, programs or updates that users can download from the Internet. Developers of trojans use various strategies to trick users into letting malware into the system. Specialists from Les Virus infrom about the most popular methods:
Thus, it's important to be careful when browsing online in order to avoid cyber infections. Always use legit download sources, stay away from suspicious ads and emails. Installing and regularly updating security program is also needed for computer's protection.
- they upload obfuscated free or cracked programs that are actually malicious (e.g. if you download cracked Photoshop from peer-to-peer networks or torrents, it might actually be a trojan);
- they can use pop-up ads that warn about available Java or Flash updates;
- they might display banners on websites that claim about detected viruses and urge to download security tools to clean the device;
- they might include trojans in email attachments that look like safe and important documents.
How to remove Trojan-spy.win32.agent.gen
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: Delete scheduled tasks that bring it back
Open Task Scheduler from the Start menu and click Task Scheduler Library. Select each task you do not recognise and read the Actions tab:
- a task that starts a file in
%AppData%or%Temp% - runs
powershellwith a long encoded line - opens a web address belongs to Trojan-spy.win32.agent.gen or a similar program
Right-click such a task and choose Delete, and check the subfolders too. Leave tasks from Microsoft, your PC's maker and programs you use. Task Scheduler is the same in Windows 11 and Windows 10.

- a task that starts a file in
Step 2: Remove it from startup
Whatever Trojan-spy.win32.agent.gen installed usually starts with Windows. Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.
Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

Step 3: Delete the folders left behind
What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through
%LocalAppData%,%AppData%, %ProgramData% and the two Program Files folders.Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold
.exe,.dll, .js or .ps1 files are the strongest sign.Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 4: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 5: Change passwords from another device and sign out other sessions
Assume that the passwords saved in this PC's browsers, and the accounts that were open in them, are known to the attacker. From a phone or a clean computer, change the e-mail password first, then banking, shopping, social and gaming accounts.
Use each service's option to sign out of all other sessions, because stolen cookies keep a session open even after a password change. Turn on two-step verification on each account. Wait with the infected Windows 11 or Windows 10 PC until the scans are clean.

Once you download security software, update it and run a full system scan. If you cannot download or run security software, you have to reboot your computer to Safe Mode with Networking. You can find the guide below.
[GI=method-1]Rebooting Windows computer to Safe Mode with Networking allows disabling the virus and run security software:
[GI=method-2]System Restore method is another way to disable trojan and run security software for virus elimination:
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 trojan-spy.win32.agent.gen in the list of installed apps 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.

Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.
Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings.
Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.
Questions about Trojan-spy.win32.agent.gen
What is Trojan-spy.win32.agent.gen and why is it on my PC?
Trojan-spy.win32.agent.gen is a program that was installed on the PC, most likely together with something else you downloaded. Free software sites and many installers add extra programs on setup pages with pre-ticked boxes, so the extra install looks like your choice even though nobody read the page.
Check the install date in Settings, Apps, Installed apps: the program you installed that day is the probable carrier. If you do not need Trojan-spy.win32.agent.gen, uninstall it. If it belongs to your hardware or to a program you use, search its exact name and publisher first, because drivers and their tools can have unfamiliar names.
Trojan-spy.win32.agent.gen came back after I uninstalled it. Why?
Something else is reinstalling it. Common causes are a second program from the same publisher, a scheduled task that downloads it again, or a browser extension that keeps prompting for it. Sort Installed apps by install date and uninstall each entry from the same day that you did not choose.
Then open Task Scheduler and look in the Task Scheduler Library for tasks with updater-style names that you do not recognise. Check Startup apps in Task Manager too. If Trojan-spy.win32.agent.gen still returns, start Windows in Safe Mode, uninstall it there and run a Microsoft Defender offline scan, which looks for loaders that ordinary scans can miss.
Which malware family is Trojan-spy.win32.agent.gen?
That is not known yet. Trojan-spy.win32.agent.gen has been reported by people who saw trojan-spy.win32.agent.gen in the list of installed apps, but no sample has been analysed publicly, so security companies have not assigned it to a family. The name you see may be a file or program name chosen by the authors, not a family name.
This does not stop you from removing it: the startup points, the offline scan and the account steps are the same for most families of this type. If Microsoft Defender or another scanner gives the file a detection name, write it down; that name is the best clue to the family and is useful when you report the incident.
Why didn't my antivirus stop Trojan-spy.win32.agent.gen?
New trojan builds are packed and changed often so that signatures do not match, and some are signed with stolen or bought certificates. Many arrive inside password-protected archives, which scanners cannot open until you extract them.
Some downloads also tell the user to turn off the antivirus "because it gives false alarms", a common line in cracked software instructions. Keep real-time protection on, never disable it for an installer, and run the offline scan whenever you suspect something slipped through.
Is it safe to do online banking after seeing trojan-spy.win32.agent.gen in the list of installed apps?
Not on that PC until it is clean. A program that produces trojan-spy.win32.agent.gen in the list of installed apps 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.
Is a trojan infection worth reporting to the police?
If there was harm, yes. Unauthorised payments, accounts used for fraud, blackmail or a remote session during a scam call all belong in a report, and banks often ask for its reference number before they refund anything.
If antivirus caught Trojan-spy.win32.agent.gen before it ran and nothing was misused, there is nothing to report. Keep the evidence anyway:
- protection history
- the original download
- the dates
Businesses may also have to notify a data protection authority if personal data could have been accessed.
Can Trojan-spy.win32.agent.gen spread to other devices on my network?
Most trojans aimed at home users stay on the PC they infected, but an attacker with remote access can look at the network, open shared folders and try passwords on other devices. Loaders sometimes deliver worms or ransomware that do spread.
Disconnect the PC while cleaning, run a full scan on other Windows PCs, change the router's admin password and the Wi-Fi password if they were saved on the infected PC, and update the router's firmware. If other PCs show the same detection, treat them as infected too.
Can a normal remote support program be a backdoor?
Yes. Tools such as AnyDesk, TeamViewer and ScreenConnect are legitimate, but whoever controls the account behind them controls the PC. Scammers install them during fake support calls, and some trojan campaigns install them silently because antivirus programs do not flag a genuine, signed product.
If you find one you did not set up, uninstall it, check Startup apps for related entries and change passwords from another device. If money or accounts were involved, call your bank and report the incident.
Should I reset my PC because of Trojan-spy.win32.agent.gen?
Only if the signs point to deeper access. Reset when you see trojan-spy.win32.agent.gen in the list of installed apps again after removal, when Windows Security cannot start or update, when remote access tools you did not install keep appearing, or when you simply cannot trust the PC any more.
Otherwise, the plan in this guide plus an offline scan is enough. If you do reset, choose Remove everything and Cloud download for a fresh copy of Windows, restore only documents and photos, and reinstall programs from their official sites. Change important passwords from the clean system afterwards.
Will Fortect remove Trojan-spy.win32.agent.gen?
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 Trojan-spy.win32.agent.gen, 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.
