What Should I Do After Finding a Trojan on My Laptop?

Asked By GamerGal2023 On

I recently downloaded a game from a site I trust, but after scanning my laptop with Malwarebytes, it detected a Trojan in the game's executable file. Unfortunately, I had already run the game before scanning. I checked the file on VirusTotal, and it flagged the Trojan with 29 out of 73 reports indicating it's probably not a false positive. After that, I turned off the Wi-Fi, uninstalled the game, deleted the quarantined Trojan, and performed a full scan with Malwarebytes, then restarted and ran an offline scan with Microsoft Defender. All scans indicated no malware or Trojan left. I'm planning to change my passwords on my phone, which shares an account with my laptop. What's my next step? Is it safe to upload my PDFs to Google Drive and should I reset my laptop?

Make sure to run Malwarebytes and Microsoft Defender again just to double-check that everything is clear. And yes, using 'sfc /scannow' is a good idea—it checks for system file integrity issues. You can find Malwarebytes on their official site, and it's easy to install. Regarding reinstalling Windows, you can usually do this through the settings under 'Update & Security'. It's a bit more involved but just follow the prompts, and be sure to back up everything vital first!

First, it’s great that you took immediate action! Just to be sure, I’d recommend restarting your laptop and running another scan with your antivirus software. Sometimes threats can surface after a restart. If all comes back clean, you should be fine. However, for maximum safety, consider backing up your important data, like photos and documents, and then reinstalling Windows. Oh, and definitely change your passwords starting with your emails since that’s often the most critical point. Using a password manager like KeePassX can help manage unique passwords for your accounts, which is a smart move! Good luck!
