Potential Malware on PC. FRST help requested
Hello, around a week and a half ago (I believe the specific date was 5/2/2026) I downloaded some mod files from a Mario Party GitHub repository that looked legitimate. However, a few days after those files were downloaded, I received this popup from Windows Defender. Please let me know if the image ends up being too blurry to read, I’ll type out its contents in a comment if necessary.
Anyways, I initially believed it was a false positive as none of my accounts on my PC had been hacked (they actually still haven’t been hacked interestingly enough, and I’ve already changed most of my passwords to my accounts on a clean device. Haven’t gotten around to everything though, I decided to do this before continuing) but I noticed that my computer’s fans seem to be running louder than they were previously and my PC blue screened a few times on either last Friday or Saturday with the MEMORY_MANAGEMENT error (I’d like to note that the blue screening has happened in the past a few times (never multiple times a day though) before the potentially compromised files were downloaded and that the fans running louder may be a symptom of a different issue).
For attempted remediation, I’ve cleared out my Recycle Bin (they were deleted from my downloads by the time they were flagged) where all of the files were located and have ran over a dozen antivirus scans from Windows Defender, Malwarebytes (which I’ve since uninstalled due to the trial running out), ESET (which I uninstalled after a few scans due to some strange e-mails saying scans were conducted with 0 files scanned), HitmanPro, F-Secure, BitDefender (which I’ve also uninstalled), and Emsisoft Emergency Scanner. All of them have come back clean with the exception of HitmanPro which detected some cookies but no actual malware. I also ran Malwarebytes in Safe Mode as well, nothing detected there.
I’d like to note that I also did not run any of the files listed in the Windows Defender report. I did run a file from the folder, but it is not listed here. I uploaded one of them to VirusTotal and it got a 25/70 score I believe.
With all of this being said, I would like to avoid reinstalling Windows if possible as none of my accounts have been hacked and I don’t particularly want to go through that process especially if my system ends up being perfectly fine. I’ve already downloaded FRST and ran it as instructed in the pinned post about FRST in this subreddit. I’ve also posted the logs to the malware analysis website also found in the previously mentioned pinned post. The keywords are as follows:
