Actually, while the former is right (there's more than just virii out there), the latter (av software doesn't identify mal- and spyware) isn't. At least not with the av app that I'm using, which is Norton Antivirus. The newest version of that one actually incorporates malware and spyware removal into the antivirus scanner. Personally, I think that one was loooong overdue because the two fields are so closely related and all. So, it was just a matter of time before an av app came up with adding spyware, adware and malware removal to their features.
It's nice not to have a second app for malware protection anymore. Until recently I used to scan my system regularly with Spybot and Adaware. I did so several times after I upgraded to Norton AV 2006 and since the two didn't come up with any malware anymore, I stopped scanning with them completely now and leave it all up to NAV.
