I'm running W7 Ult x64bit that I just discovered was not from an "untouched" iso. I've ran Virus checks on the iso I used with Avira and malware checks using Malwarebytes and nothing turned up. I now have an untouched iso that checks out OK using the Hash check method and am wondering if any of you folks feel that I should do a repair install with it, or wipe everything out and do a clean install? Or, being that my original iso checked out OK virus and malware wise should I do anything? Thaks in advance.
