Greetings to you.
I've been running xp for sometime now. Got a friend at Microsoft who put me right.
Some anti-virus applications are just too heavy, take up too much space. The best combination to use for xp set up is as follows, best of all it's all free. Go to zone alarm and download the free version, brilliant fire fire wall. Go to Grisoft and download free avg, brilliant virus catcher. Go to Lavasoft and download free Ad-aware 6, brilliant spyware. After you've downloaded this combination nothing can get through after proper configuration. Play around until you figure it out. Last but not least, go to Gibson research and check out the patches and advise this guy has. Brilliant fellow, even answers your email enquiries. This site also has links to other handy utilities and tips. When ever you download or uninstall any programs from your xp, CREATE A RESORE POINT, xp is the best at the moment but then again it is microsoft. Good luck.
