10 days ago I used a USB because I needed a document that was on an old family computer (last used in 2015). Long story short, Windows Defender quickly detected a “Backdoor: MSIL/Bladabindi.AA” and “Trojan: Win32/Phonzy.C!m”. I did not open/move/run any files and dealt with the threats via Windows Defender. It succeeded with the backdoor, and a “remediation incomplete” with the trojan (by then I removed the USB).
With this subreddit’s help, I used these programs throughout the 10 days. They found nothing: RougeKiller (safe mode and without), The Kaspersky Virus Removal Tool, Kaspersky TDSSKiller, Emsisoft Emergency Kit, ESET Online Scanner, HitmanPro (safe mode/normal), Malwarebytes Premium Trial (safe mode/normal), Microsoft Saftey Scanner (safe mode/normal), Microsoft Malicious Software Removal Tool, and Windows Defender (offline custom, full, and quick). I also reset browser data and deleted Temp files in safe mode, cookies, and even trusted extensions marked as a PUP by the programs.
Nothing so far acted oddly or has been compromised to my knowledge despite frequent usage. Is it relatively safe to conclude my system is clean without formatting it?
