Usually, the easiest way to tell you have spyware is because your PC is running at a reduced speed. The other way to check is to hit CTRL+ALT+DELETE and hit task manager (if you have windows service pack 2. If you have before SP2, then this should automatically bring up the task manager).

Once the task manager is open, check your running processes under the “Processes” tab. If you see a lot of strange processes running you don’t recognize, you likely are infected with spyware, ad-ware or viruses.
An example of strange processes would be a fgkosk.exe or copies of the same process running twice. Some “smart” spyware can actually disguise itself as other windows processes - you can tell this if you have copies of processes running. Don’t end task anything you’re not sure of - besides, most of these files are actually able to resume themselves after you close them as they’re in your windows registry.
You could also download a program that checks for these infected files, such as Avast, Ad-Aware, etc. Check my other article on “what to do once you have spyware” for a list of good programs to use.
The best way to get rid of spyware, ad-ware, or viruses once you have them is either to use a program made for doing exactly that. Failing that, you could format your PC. Sometimes, an infestation becomes so bad you may have troubles downloading, installing, or running a program that can help.

Computer viruses are more like their biological counterparts,leaves the same to Computer once if it gets affected. If you think your computer has been infected bu viruses, the only safe course of action is to use a good anti-virus program.
Step1:As soon as you suspect that your computer has a virus, remove your computer from any networks it might be on, as well as from the Internet, so that you don't inadvertently spread the bug to others. Unplug your network cable if you have to.
Step2:If you have virus-scanning (anti-virus) software installed, run it.
Step3:If you don't have anti-virus software, you'll need to obtain some. If you can't get it from a network administrator or download it from an uninfected computer, you can mail-order it from a retailer.
Step4:Start your computer (still not connected to a network) and follow the instructions that came with the anti-virus software.
Step5:Keep running the virus-scanning software until your computer comes up clean.
Step6:Reconnect your computer to the Internet and check with the anti-virus software's publisher to make sure you have the latest updates. If not, download them now.
Step7:After updating the anti-virus software, run it again until your computer comes up clean.

Warning:There's no substitute for prevention. Good anti-virus software more than pays for itself as long as you keep it up-to-date.Common sense also goes a long way toward keeping your computer clean.
Never open an attachment from someone you don't know, and be suspicious of odd attachments from people you do know (a virus may have mailed itself to you from their computer).
