Problems Running 2 Different Anti Virus Programs
While it is possible to run two different anti virus programs there can be issues with system performance and email as both systems will want to process all the same files.
If you want to setup a belt and braces approach if you are worried that your antivirus program may have meen compromised then periodicly use one of the online antivirus scanning sites like
Housecall from Trend. Inability to access any of these online scanning sites can be the first indicator that you do have bugs! as they block them to avoid removal.
Also add in off line scanners like spybot search and destroy and malware bytes should keep you running clean.
Hope that helps.
