I see MalwareBytes recommended many times here. Is this because it's better suited and has fewer problems and conflicts with McAfee products than other similar tools? On my old Windows XP PC, which I'm about to dump, I use SpyBot Search & Destroy to manually scan for issues but disabled all the real-time features. So, which Spyware/Malware product should I use on my new Windows 7 PC running McAfee products?
No, my new PC is Windows 7 SP1. I'm dumping my old Windows XP SP2 PC as it has developed Windows software issues and I can't update it to SP3 even after performing various "tricks" advised by Microsoft. Anyway it's too old and slow to be of any value even if I wasted my time re-installing everything to fix the issues. The new PC is so much faster.
I'll take your advice and use Malwarebytes for starters. I might install SpyBot later but as I've done on my XP system I'll disable all the real-time features, such as Teatimer.
