Does Internet Antivirus Protect Ours Computer From Virus Well..!?

Kaspersky the most popular antivirus among the others, some said it awards as top 1 of 10 but somehow there is another competitor, which is Bitdefender and Norton. This is making me confuse, which is the trusted can be used!!?

Well, I had been using Kaspersky for 2 years. I can said the protection is not satisfied because the upload on sever are slow leads the database not completed to work the scans. Major problem is my computer interrupt virus few times in a years and the virus couldn’t neutralize completely.

I'm intend to change to other products either Bitdefender or Norton, guys if you have any opinion please don't hesitate to tell me. Thanks!
