i have a computer that has some crazy virus's. im guessing its rly bad being i cant even get on the internet cuz of it. i had geek squad out at my house and wanted to charge me $550:00 i thought that was outrageous is there anything i can do to fix this. dont have much extra money cheapest way possible plz..

Have a look at:

Viruses/Spyware/Malware Preliminary Removal Instructions

but i cant get online with that computer

Then the only option you have is to remove the internal HardDrive
Then mount it in another computer as a secondary drive
(actually there are external HardDrive adaptors too, like USB)

Then scan it from that computer's Antivirus

Then, once clean, return it to the original computer
