How do I fix my PC after accidentally installing a virus?

First, you should definitely run Malwarebytes, RogueKiller, and ADWCleaner to scan for and remove any malware. These tools are pretty effective at detecting and cleaning infections. If you find that the malware is persistent, consider backing up your important files and performing a clean install of your OS to ensure everything is wiped clean. Don't just rely on antivirus software—malware often hides deeply in the system.

I looked up your situation. It sounds like it might be a false positive since three out of 70 detections isn’t that convincing. Check under the "Details" section on VirusTotal; the scan showed it was uploaded two weeks ago, so it’s likely not a brand new virus. That said, if you're still worried, it's best to run some cleanup tools just to be safe.

If you're really concerned and just want to be thorough, the best approach is to do a secure wipe of your computer and start over. This way, you won’t have to second-guess whether you've removed the virus or not. Just make sure you back up your essential files first!
