I've just installed the latest Foxit Reader - this download included "McAfee Security Scan Plus", which I suppose is a virus checking program. I am a bit wary of this - I already have Avira Anti Virus, and Malwarebyte, and Super Antispyware - I don't want to have a conflicting av program. Is the McAfee app. any good or would it be best to uninstall? Advice appreciated.
