I've been using AVG Pro v.7 for quite some time, but I sense from reading this and other forums that it is not highly regarded. I have an older computer, 500mhz, 384 RAM, Win XPSP2. I have had no problems with AVG and it doesn't seem to slow down my comp. I've tried KAV 5 and NOD32, but neither agreed with my setup; NOD32 slowed the computer down considerably (suprisingly, since I've read that it was light on resources), and KAV and my Sygate FW did not get along re its updating. KAV also appeared to slow things down a bit. I note that F-Prot does not have an email scanner, but it seems to have a reputation for having a higher detection rate. I am test driving F-Prot and it, like AVG, has little if any impact on resources. I'm wondering if anyone has a recommendation between the two. Is an antivirus without an email scanner safe? If so, why do so many of the others include email scanners? Thank you.
