I have a roommate who currently uses AVG free and Windows Defender. I'm trying to migrate her to NOD32 antivirus, as I think this would offer her much better protection and system performance, but she is fanatical about Windows Defender being on her PC and insists that any program I install be compatible and cause no issues. I know NOD32 is compatible with most adware/spyware programs from what I've read in newsgroups, but I have not seen any comments concerning NOD32 and Windows Defender, so I told her I would ask this question in the NOD forum before I downloaded and installed the NOD32 trial for her to evaluate. I would appreciate your comments or links to any comments concerning NOD32 and Windows Defender compatibility for her to read. Thank You.
