Since unknowingly downloading this spyware to my PC running Windows XP, (Smmon.exe and Bpmon.exe) I can no longer log in to any of my email accounts, I keep getting the login screen back (using Orange and Yahoo mail) Is this spyware the reason for this and if so, how do I get my emails back? I think I've removed the spyware using advice from other forums, but none seem to mention a problem with email.
Use system restore to go back to a time before you had the spyware. You will have to go into safe mode if you have XP home (or with XP Professional if you haven't got rid of the spyware properly).
Have you used software to get rid of the spyware?
