yes i got the nasty Windows Securtiy Pro virus and i removed it but then i just made a quick check on the system32 and i deleted svchast (which ik needed to be gone) but then i read on another forum that i must delete desot.exe so I did and now when i click on any executable i get the "open with" box that makes u select a program to open it with. so i was wondering HOW DO I FIX THIS!!!!!!!!!!!!!!!!!!
