AVG doesn't have very good heuristics. If you want a good anti-virus, expect to pay for the subscription.

McAfee? Norton? Both of them are very memory-heavy, and will slow your computer down. They're not bad: they're better than ZoneAlarm. I recommend Norton. The two companies are renowned for hogging memory (RAM: speed of computer) and having pesky notifications, and being impossible to uninstall properly.

For firewalls, WIndows XP has its own "Windows Firewall", but if you want to go beyond that, PC Tools (creator of Spyware Doctor) Firewall Plus: http://www.pctools.com/firewall/ . It should, however, be already included in a paid security/anti-virus software like Norton.

mine is grisoft avg for me in my pc its more effective.

I use Avira Antivir Personal Edition Classic..very effective... why don't you give it a try.

mine is bitdefender....

I have moved from Symantec to NOD32. Its much better, a lot cheaper and gets the job done

i'm using karpersky....

One and only Nod32, and with him i use spybotsearch&destroy.
I have no problems with them.

My vote is for Avast. It's free, doesn't take up too many resources, scans for viruses & spyware, and actually works. What more can you ask for.

I agree, I also use it and it's very effective and free as well. I was using AVG before but I had some issues with it that's why I switched to Antivir

I use my computer since last 8,9 years. I use many of them. Some of them are failed to protect my Pc from viruses. Anyway Right now Im using AVG free edition and some time I use Kaspersky. Its also a good one.
