Question Malware modify, delete, corrupt files
Not all malware is made to damage or delete files. The ones that can access, change, or destroy your data are usually viruses, worms, Trojans, ransomware, or wipers. The ones you mentioned, like QtWebKit4.dll, Caller.exe, and Rhadamanthys, are Trojans that mostly download more malware or steal information. They don’t usually corrupt files directly, but the extra malware they bring in can cause serious harm.
I've used several antivirus programs, including Bitdefender Free. I recently activated and ran a full scan with Microsoft Defender, and it found a single malicious file: QtWebKit4.dll (Trojan:Win32/Wacatac.C!ml). But before that, I used several antivirus programs, including Kaspersky Free and Malwarebytes Free, and they didn't detect anything in the scan. So, I thought, did this malware find alter, modify, delete, or corrupt any personal files on my PC? In the same folder as this DLL, there's another folder, and inside it, there's a Caller.exe file. Defender didn't detect it as malware, but VT 2 detected Trojans. I have doubts if malware active corrupt, modify, delete any file in my PC.
