Please see my other topic for more information about this issue:
Hello. I have McAfee Total Protection installed on my computer. After the GUI was changed, some features of the antivirus program have been broken. First of all, Real Time Scanning does not start. It says "Starting...", but it just never starts. Also I cannot run a scan. When I open either a full or quick scan, it says "Percentage completed: undefined%", and the scan doesn't start at all. The software is non-functional. I also have SUperantispyware and Malwarebytes Antimalware installed on my computer as stand-alone scanners, without real-time protection. I think that maybe they are having a conflict with McAfee Total Protection, or the McAfee software itself is compromised. I think that maybe McAfee Total Protection has been hijacked, or something. Perhaps this has something to do with John McAfee leaving the company to be run by inept "security specialists". What antivirus/antimalware program would you guys recommend in place of McAfee Total Protection, because it just does not work at all?!
