Download MicroWorld virus scan here >>> Micro World http://www.mwti.net/antivirus/free_utilities.asp

To run the virus scan make sure you click the following

memory, registry, startup folders, system folders, services, drive (all drives will be added) then click on scan clean. When the scan is complete hilight all the files in the LOWER box. Then ctrl + c and paste them into the thread ctrl + v.

I warn you the scan will take a long time to run and will not fix anything just identifies bad files.
