Free VS paid antivirus? What is your opinion? just a poll, hope i get many answers.?

We all have been using anti-virus softwares on our pcs whether free or paid.

And heres my experience......

I have used free anti-virus and spyware such as avast,avg,spybot search and destroy,spyware doctor,spysweeper,ad-aware and many more.Most of them slowed down my pc's performance and i dont know why?.Also they were not effective enuff to protect the pc for simple fact i had to reformat my pc due to virus attacks on prior instances.

On the other hand i am currently using paid versions of kaspersky and Norton on my pc's and honestly i feel they are working good for me.I dont know why but many people hate norton but from my personal experience i find it very easy, effective and trustworthy.Also its not making my pc slow.Likewise with kaspersky, infact it has made my pc work faster than ever.

What do you think, guys?

I myself, have AVG and it slows my computer down so much... plus about every morning i find itself doing a computer scan,not to mention that it's daily updates every time you start up your computer is a pain in the butt! in my short experiences of paid antiviruses, i noticed it is a lot better, and it doesn't ware my computer down.
