I'm in desperate need of help.
About two days ago, I used my friend's flash disc in my laptop (IBM, OS: Win XP home edition). Upon inserting the USB device, my AV (Norton, 2004 version) immediately alerted me of a virus in the flash disc (unfortunately I didn't catch the name, but the file was jged.exe triggered by an autorun). A few minutes later, my computer rebooted by itself.
At first I thought nothing was wrong since everything was working fine. Then I tried to use the task manager to close a program and was surprised to find out that it was "disabled by the admin". I searched around the net for a fix for this, and found a solution through regedit. To my surprise, regedit is also disabled.
I checked the web and found out that viruses can do this. So I tried to access my Norton, but it won't open (nothing happens, not even an alert message). I tried to access an online scanner, but nothing happens as well (screen doesn't load). So I followed another advise from the net to enter in safe mode, but every time I try to, the screen goes blue saying Windows has encountered an error then switches back to booting normally.
Tinkering around, I also noticed that my firewall was turned off (even if I turned it on, restarting causes it to switch back to being off). I also have trouble unhiding folders (somehow, it reverts back to being hidden).
I managed to access the regedit using the gpedit.msc plus some other command I found on the net. I deleted the regkeys that enable/disable these functions, but somehow, after a few seconds, it returns. I also managed to find .exe files hidden in my computer using processexplorer, but everytime I restart, these randomly named .exe files just keep reappearing.
I download Superantispyware and malwarebytes. Both programs detected malwares and removed then, but after restart, the malwares are back.
Well, that's about it. I don't know what else to do.
Thanks in advance for any help.
