Which Virus Checker?

Hi everyone! I currently am using Windows XP Home version. I got all the quirks figured out and thank you all for your help! :) Now just some advice. I have AVG anti virus agent I use and I removed Nortons from my system. Is AVG sufficient enough? I've been reading that 2003 may be a bad year for viruses and I want to make sure I am prepared. I keep it updated through the automatic updating. Thanks for any information!

AVG works great for me, but I'd also manually check for updates often too. I check each day when I start the computer, and it only takes a moment.

Thanks Gerdog for the information! I will also check manually for updates! Have a good night! :)

NAV 2003 has been great for me.
i never use to use one at all, but with virus's inserted into webpage coding , you definately should these days :)
