Im not a computer genius, but I think I got some kind of virus and for about 10 minutes my computer got a mind of its own. I tried to watch a video on megavideo (on firefox, not IE) and then I got a message on the right hand side of the task bar telling me the firewall wasnt on (even though I didn't turn it off). I went on the windows website and downloaded one of those "fix it for me" things to switch the firewall back on.
So after that I thought (because it went so crazy) that I should do a full computer virus scan (I used AVG free version 9) and it found 4 threats, and got rid of them, so my computer was working fine again.
So I tried to open firefox again, using the icon on my desktop, and the "chose the program you want to open this file with" message came up, so i chose firefox, and it worked. But, thats the only way i can get it to work, and, every icon on my desktop, and every programme in the start menu does the same thing when i try to open them, the only one which seems to work is firefox, everything else just says that it cannot be found.
The only way to get onto programmes now is to go through a file, for example, the only way to get onto Adobe Photoshop would be to select a photo, right click and select "edit file in Adobe Photoshop" and the only way to open up AVG is to select a file, right click and select "scan with AVG Free".
I've tried to system restore, but the same thing happens, when i try and open it i just get the message telling me that it cannot be found.
Iv'e also tried to re-install firefox, but when I try and open the installer, it does the same thing again (the message I'm talking about is this one http://img130.imageshack.us/img130/456/error1z.jpg ).
Can anyone please tell me whats wrong with it ? Or how I can fix it, or how I can open system restore using the "Start>Run" way?
