I agree many virus's can be "cleaned" and if you don't have a anti-virus there are plenty of free ones out there that work great. AVG, Avast, etc. While it doesn't hurt to do a clean OS install every once and while it doesn't have to be the way to get rid of some viruses. If you already have AV protection but it is not up to date because it costs money than remove/uninstall it before adding a new free one. Multiple AV programs running will decrease the system's performance. Do a google search on the virus name and you should be able to find info on how to clean it.Originally Posted by SarahMB
