here is the website to compare
http://usa.kaspersky.com/products_services/compare/

and they are both excellent products.

If you just need an antivirus there are a lot of good products free
Avast,Bitdefender, AVG, and even MS' own Security Essentials.

For a Free Fire wall Commodo
for FreeAntispy/malware Spybot or SpywareBlaster Malewarebytes Anti-Malware

A google search will turn up the download sites

any of those would serve you well if you keep them updated.

I currently have Kasperkey Internet Security for 3 users. It is about to
expire. I'm wondering if I should purchase the 2010 version of it I should buy
the Kasperkey Anti-virus instead. What is the difference and which one is
better?
