i think this happened after i installed a game, but i uninstalled it again and it hasnt changed the speed of the startup, its still slow.

BTW I ALWAYS PERFORM DISK DEFRAGMENTER, REGISTRY DEFRAGMENTER, DISK CLEANER, REGISTRY CLEANER, AND VIRUS SCANNING. I HAVE ALSO DISABLED EVERYTHING FROM "MSCONFIG" EXCEPT FOR MY INTERNET SECURITY.

the shut down and running is still good, but its only the startup so why has my pc slowed down?? please help!!
oh yeah and i have also disabled many services that i dont need.

I’ve tried Trend Micro, McAfee, Norton, Registry Mechanic, CA, and several freeware programs like Zone Alarm, AVG, Advanced System Care, Spyware Blaster, Easy Cleaner, and most recently COMODO Internet Security. It seems to me like they all worked somewhat well for a while. Seems like either the program gets too cumbersome or the PC ends up slowing way down. Even had 3 PC’s die after getting slow. Got a laptop now that’s really slowed down. Do you just need to switch security providers frequently? Who do you trust??

I need some good programs to speed up my computers performance because it is very slow.

I need programs like anti-spyware programs (or will AVG internet security paid) do it, it has anti-spyware) and malwarebytes (does AVG internet security paid have that?).

Also just normal cleaning programs to make my computer faster.

I keep getting these "offers" in the form of pop ups to scan my computer for adware, malware and registry cleaners too. I have ran my Web root spyware program as well as my avast anti virus to no avail. These "offers" seem to be slowing the internet substantially on my one computer. Though the rest of that computer seems to working fine. How do I get rid of these popups. I have set my internet security and privacy at high levels. Nothing seems to work. Any ideas? Programs I can download to stop this. Please help

I use AVG internet security already which is quite comprehensive, has anti virus, firewall,, anti spyware etc etc. but are they any other programs you would recommend?

Ie a registry cleaner, a trojan remove etc etc?
