Hi guys,
I've always been able to fix my own problems.. but this time I actually had to sign up for other advice..
Currently running Windows XP SP3
The irony was: I updated AVG 8.5 to AVG 9. (Computer was running fine with no viruses)
After AVG 9 was installed, computer automatically restarted, and when it restarted, my startup programs wouldn't load. It was weird so i tried to manually start them up and everytime i click on an .exe (like MSN msnger), it opens up the avgui.exe screen. I couldn't even "add and remove programs" to do an uninstall of AVG 9, it'd direct me to avgui.exe and opening the user interface every single time..
So I restarted in safe mode, AVG's dll still hooked onto the startup process, I couldn't terminate AVG.
Then I restarted in safe mode with command prompt. Did a "cd program files/avg9" and successfully del all the files in AVG.
Yay no more AVG! But.. now instead of the avgui.exe popping up, a "Please choose a program to open with" dialog box pops up everytime i start an exe. And when i try to open control panel items such as add and remove programs and computer properties, it comes up with "C:\Windows\System32\rundll.exe" application not found.
Funny thing is, iexplorer.exe works only from the desktop, not from the taskbar.. hence i'm on it right now. I do not believe I have a virus, just some registry files messed up by AVG. I can't run any .exe files normally (usually you just double click), I have to run them "as Username" and enter my password, when im already logged onto the same user..
I tried running ComboFix. It lets me if i run as "my username", but when combofix attempts to open iexplorer.exe, it pops up with the "Please choose a program to open with" dialog box..
All this happened during exam week in my senior year of university. Yay.
After all's been said, do you think it'd work if I somehow create a new user account? I can't do it using control panel because Rundll32.exe application not found.. so is there a way to create a new user via registry?
Please help!
