Question
we have an older pc that is used exclusivly as a timeclock for employees. Obviousley someone has been visiting porn sites recently and now in the last couple days there are hundreds of different sites appearing on the history page. When I go to view temp files the times that they show are every few minutes and no one is currently on the pc. Thanks to security camera we stopped the person responsible but now how can I stop these unwanted sites? I'm sure there are probobly worms and virus threats also.

Answer
Hi Marshall,

To block the sites, check out the following for information:

To check for viruses and/or spyware, ssing Internet Explorer, go to:

http://security.symantec.com/sscv6/WelcomePage.asp

Click "Continue to Symantec Security Check", in the next window click No when asked if you want to close this window, that will bring you to a window where you should click Virus Detection.

Write down exactly anything it finds, then go to: http://www.symantec.com/search/  and do a search for what was found. Symantec usually has a removal tool and/or directions for removing manually. Make sure that you follow the instructions for removal, step by step, especially the part regarding disabling System Restore.

I would also suggest downloading Malwarebytes Anti-Malware 1.37 from:

Hope this helps!
