Which internet security is the best ever?best antivirus software

Personally i would recommend Norton.The older versions used to have the problem of slowing down your pc,but they have sorted that problem out now.It's quick at scanning,has a very user friendly interface, a very good detection rate,regular definition updates and of course it has the online protection centre.

kaspersky antivirus is the newest one and is the best
i like using trendmicro and it is rated as the #1 anti-virus
i would recommend kaspersky internet security,its very good.
addition Kaspersky, McAfee, CA, Nod32, AVAST Avira %26lt;any of these av programs%26gt; and your common sense is the best security.

AV+common sense=best security
You can try Ad Aware, Spy bot - search and destroy and Spy ware Doctor for some good spy ware removers. AVG Anti virus and McAfee virus scan are also supposed to help a lot to remove virus. check out http://blog.360.yahoo.com/blog-sAFtLsc8e... for more details.
NORTON INTERNET SECURITY. this is the best because i have had no virus that has intruded my PC for the last 6 years with Norton Internet Security. i dont think it slows my computer down. but because i install it whenever i get a new computer, i cant tell. TRUST ME it is the best even Which? magazine says with like 98%. This is made by Symantec.
