how can u tell if your computer have an virus on it

If you think you have a virus, the virus can do strange things. Open up programs you are not using at the time. Make the computer run slow or you may not to be able to use programs you normally do. A virus can do lots of things to your computer. Make sure you have a good anit virus and run it everyday. I run mine twice a day due the fact I am on alot with my work and so want to make sure I do not get a virus.

Programs run slow or won't open. You get odd error messages. Programs shut down with reason. You notice files that were not there before.
