Computer with VirusIt's best to avoid computer viruses, but sometimes it's just too late.

If your computer has been infected with a virus, there are free virus removal programs that you might first try using to clean your computer like Malwarebytes, Spybot Search & Destroy, and SuperAntiSpyware. Sometimes, however, you will be unable to use these programs because your system has been damaged or the virus has modified settings in such a way that you won't be able to even run these programs.

Speaking With the Tech

Ask whether he can guarantee his work. You might expect a one-month warantee from some techs who promise to make your system more secure after repairing it. After all, the tech should look for the underlying cause of whatever let the virus in in the first place. Ask the tech whether he ever just wipes the system. Be sure that he will not do this unless you have nothing of value on there (and, if it is the case that you have nothing of value left on your computer, then it is likely that you could get the job done for less than a "virus removal" service would cost). This should be a last resort considering the time it takes to get your programs installed and the work involved in setting everything up just right. There have been plenty of horror stories where large retail chains simply wiped the system without first checking with the customer, and all photos and documents were lost. You might insist that a backup of your data is performed before the virus removal procedure is performed. A technician should be able to do this without having to boot into your computer, preserving the computer in its state exactly as it is before he begins to work on it.
