I have a heavily infected computer with a mix of viruses etc. I need help fixing it!?

I have a ton of viruses, malware, adware, spyware, trojans, etc. It's blocking me from using task manager and computer settings. I used SuperAntiSpyware Deluxe and Avast! but they're not doing much. Help!

I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following link. http://www.computeractive.co.uk/... On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps
I recommend you to reinstall your Operating System.

But if you don't want to, you can use several software to clean your computer. Try to use CCleaner, it clears useless files, repaires bad registries. http://www.ccleaner.com/
