I have a portable hard disk that I store music and data on. Lately after I open a file it encrypts the file and changes the name to gibberish. I tried running Malwarebytes and it starts to run but keeps giving error 721 (0,5). I have to assume the malware is keeping the program from running/detecting the rouge files. Is there a way to force the program to run? Has anyone ever heard of this malware? see attached screen shots Thanks Document.rtf
