So I was on some site that downloaded 3-5 of the same file caled "Sharewithus.exe" or something like that. I was alerted of there download and of course never ran them, so I deleted them from my recycle bin. I scanned with windows defender and no threats were found, but I just want to ensure my PC's safety. Do I need to install a program to even further delete the "deleted" files on my hard drive? Or am I ok to do business as usual?
