A few weeks ago I had a virus that pretended to be a virus scan telling me I needed to get their protection and whatnot, I found a guide online to help me remove the virus, part of it included having to delete the HOSTS file in my windows System32 Drivers Etc Folder and then reinstall the hosts file. I made sure I downloaded the one compatible to XP, I dont know if this has anything to do with it at all or not but since then If I plug my Iphone, webcam, microphone etc, into my computer none of it will work wont reconize it in device manager and device manager doesn't seem to have any problems in it, ive done virus scans including a boot scan with no results
any ideas what might be wrong?
