I downloaded a zip file and windows defender flagged it as a virus. At first, Windows Defender failed to resolve the threat but my PC didn’t slow down so I ingored it. When I try to open the zip file by double clicking and trying to extract it, it crashed both my File Explorer and WinRAR and Windows Defender went heywire trying to contain it. I went to the file location and manually deleted it by getting it in the Recyble Bin and deleted it. Being paranoid about the possibility of the virus escaped and silently infecting my PC, I ran a full scan with Windows Safety Scanner and Windows Defender but it returned 0 threat. I deleted all cache and temp files and I’m currently running a full scan with MalwareBytes. My files explorer is still very slow and my disk usage is at 100%. What should I do next ?
