When I start up my computer it takes me to the login page as it should. The problem is when I type in the password it attemps to login...but logs my right back off. I have tried safe mode and it does not work. Both accounts on the computer has Admin rights, and both have same problem. I can do nothing but look at the login screen. The day before this happen I got a message that said "TrojanHorseDownloader.Generic8.AHRV" I need help ASAP because this is our office computer.
