How to remove Twoj Komputer Zostal Zablokowany virus
Nothing it reports is real.
These steps remove it and undo a payment if you made one.
Step 1: Do not pay, and undo a payment if you made one
Twoj Komputer Zostal Zablokowany virus reports problems to sell a licence: the "threats" or "errors" it lists are invented or harmless leftovers.
If you already paid, ask your card issuer to dispute the charge and cancel the subscription both in the seller's account and through your bank.
If you called a phone number it showed and let someone connect, treat the PC as remotely accessed and remove the remote tool. Uninstalling it from Windows 11 or Windows 10 does not cancel a subscription by itself.

Step 2: Uninstall programs you did not mean to install
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10, and sort the list by install date. Look at what appeared around the day the problem started and uninstall every program you do not recognise or did not choose.
Free converters, PDF and video tools, "system optimizers" and unknown browsers are the usual carriers of Twoj Komputer Zostal Zablokowany virus. If a name is unclear, search for it before you remove it, so you do not uninstall a driver or a Windows component.

Step 3: Remove it from startup
Whatever Twoj Komputer Zostal Zablokowany virus 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 4: 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 5: 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.

Questions about Twoj Komputer Zostal Zablokowany virus
What is explorer.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 explorer.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 end explorer.exe in Task Manager?
Ending an unknown process is safe in the sense that Windows will warn you before you close anything critical, and a restart brings back whatever Windows needs. Ending explorer.exe will not remove it, though: if a task or startup entry launches it, it returns at the next sign-in.
Use ending the process as a test. If something important stops working, it belonged to a program you use. If nothing changes and it comes back by itself, find and disable its starter, delete the file and scan the PC.
Is Twoj Komputer Zostal Zablokowany virus a real Windows warning?
No. Real Windows Security notifications appear in the notification area and in the Windows Security app, use Microsoft's design and never ask you to call a phone number or pay to fix anything. What people report is an unfamiliar process called explorer.exe in Task Manager, drawn by a program that copies the look of a system message.
Open Windows Security from the Start menu to see the real status of your PC. If it shows no threats while the window keeps appearing, the window itself is the problem, and the plan in this guide removes the program that shows it.
Should I reset my PC because of Twoj Komputer Zostal Zablokowany virus?
Only if the signs point to deeper access. Reset when you see an unfamiliar process called explorer.exe in Task Manager 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.
I let a technician connect to my PC because of Twoj Komputer Zostal Zablokowany virus. Is it safe now?
Not until you check. While connected, the caller could install other programs, create a user account or look at saved passwords. Disconnect from the internet, uninstall the remote access program and anything else installed during the call, and run a full scan and the Microsoft Defender offline scan.
From another device, change your e-mail and banking passwords and turn on two-step verification. If the caller opened your online banking, call the bank today. A reset of Windows is the safest option if you cannot tell what was done.
Do I need to buy antivirus after removing Twoj Komputer Zostal Zablokowany virus?
No. Windows 11 and Windows 10 include Microsoft Defender in Windows Security, which provides real-time protection, scheduled scans, the offline scan and protection against unwanted apps at no cost. Keep it switched on and updated, and turn on Reputation-based protection under App & browser control.
If you prefer a third-party product, buy it from the vendor's own site after reading independent test results, never from a pop-up or a phone call. The lesson of Twoj Komputer Zostal Zablokowany virus is that security offers which arrive unasked are the ones to avoid.
Did Twoj Komputer Zostal Zablokowany virus steal my information?
Not by itself, as far as reports show. Programs that display an unfamiliar process called explorer.exe in Task Manager are built to scare people into paying or calling; they rarely take data on their own.
The risk comes from what you did in response: typing card details into the program, or letting a caller connect to your PC. If you did neither, uninstalling the program is enough. If you did either, treat that information as exposed:
- block the card
- change passwords from another device
- remove any remote-access tool that was installed
What should I do if I already clicked or replied to Twoj Komputer Zostal Zablokowany?
Stop all contact, do not click anything else and secure your accounts right away. If you typed a password, change it at once from a clean device, then turn on two-factor authentication.
If you gave card or bank details, call the bank on the number printed on your card and ask to block or replace it. If you installed something or allowed remote access, disconnect from the internet and follow the removal plan. Keep screenshots and the message, because they help when you report it.
Will Fortect remove Twoj Komputer Zostal Zablokowany virus?
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 Twoj Komputer Zostal Zablokowany virus, 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.
