Does Comodo Antivirus Conflict With Avira Antivirus?

Also Is it good or bad to have SuperAntispyware,Spybot S&D, And Also Ad Aware all running at same time with the resident shield being on in some of them is that bad?

It is never a good idea to run more than one AV (with real-time scanning enabled) at the same time. The same goes for anti-malware applications. I would only have one of each running at the same time.

If you were asking about scanning with them I do not know of any conflicts. Just make sure that you are only scanning with one of them at a time.

By the way, there are better scanners than Spybot S&D for manual scanning. See here:
