Hey guys; I dumped "Norton Internet security" and using Anti-Vir free antivirus now. Have anybody used Anti-Vir and AVG (both free versions) Antiviruses at the same time? Do they give any system trouble? If so please let me know. I heard that both antiviruses are good and want to use the maximum protection. Also, I am running "Zone Alarm Pro 5.5" on my computer. Will the both antiviruses and and zone alarm give any conflicts? Thanks guys.
