Hello, I am running windows 7 and I came home from work and my spysweeper told em i had a trojan, "trojan.fakealert" I ran the sweep and got rid of the trojan only probem is I cannot open any files. I tried running in Safe mode, Nothing works. I go to start go to the search programs and files, I type in "Regedit" I click on that than it says "C:\Windows\regedit.exe Application not found.
