iknow macs arent 100 % against viruses but still we dont got to worry that much i was wondering what happens to a mac when it has a virus i know pc's get slow and act weird like take you to some pages and it says your pc is infectted what about a mac?:apple:

ill save u the trouble of being flamed by saying there are no viruses for the mac. i run clamxav but only because i have a windows desktop

As with PC's there's no one symptom. However, although Macs are not 100% secure, there are virtually no OS X viruses in the wild today.

You needn't worry at all so long as you don't enter your password to install any suspicious programs. Just enjoy your Mac. :)
