It's time to upgrade this PC. At the moment I've got AVG freebie. But I want to lash out and actually buy some security this time. So I want to buy on quality/performance. Saving a few dollars is not a priority. I've got ADSL with a router/modem P4 480k-ram, 2gb. My understanding is a firewall is not required due to router/modem. However I want outbound security. AppDefend firewall is included for the AV's as I read in here that it's the right thing for outbound security. So here's my short list... Kaspersky KIS security suite Kaspersky KAV with AppDefend Firewall for outbound. AVG Security suite NoD32 with AppDefend Firewall for outbound. I've trialed both Kaspersky and AVG. KiS seems to be a bit "heavy" running a system scan in the background. However I've kept it on the list due to Kaspersky's reputation. I liked AVG. It scans without hassling me by taking up too much resources. But it's not famous. NoD32 is on the list because it seems to have many loyal advocates and it reads that it is very light to run, which appeals after the KiS experience. So what do you guys think? One of the above or something else?
