Is your computer holding a secret

Yes you have a point there but i always try to keep my virus protection up to date but the type of protection i had didn't find the virus and my point is why didn't my previous protection find all those virus and dose the protection we have really work or is some of those virus software's out there giving us a false since of security, because if i had not treated and removed those viruses i really think my computer would have crashed because the screen would freeze and sometimes websites wouldnt load at all or i would get a bunch of error messages and extremely slow downloads and now that those viruses are gone theres been a big improvement in my computers performance.

If that's the case, maybe you should switch to a different virus protection program. I feel that the number of people writing viruses is increasing with that, the number of viruses that are out there are also increasing. On the other hand, people writing virus protection programs are only written to counter a virus. There is an endless possibility of viruses to be written and virus protection programs cannot be written to protect you from all possible attacks. You can prevent viruses that are currently defined in your virus protection program database but if a new virus was to come out, your computer wouldn't be protected. So in short, you are protected from older viruses but you are not protected from future viruses.

i scan mine every night

which one did you have before avg ?

I switched to AVG internet security and so far its working pretty good.

My computer seems to be working much better since i switched my virus protection i will keep my fingers crossed and hope it continues to work well.
