Cannot open any window/application on Windows Vista

[vsubram]

Hi, I have a serious problem with my system. Somehow some virus has infected my system. It keeps flashing me virus alert and whenever i try to run any program it says "Application cannot be executed. The file  **** is infected......." (not even a command prompt, notepad, task manager etc can be opened.. but with multiple tries, sometimes i get the command prompt but it is ridiculous).


Also, I've read previous topics and threads about this same issue and I tried to follow the instruction given, but I've hit a wall. In another computer, I downloaded rkill(as suggested in a previous post in this forum).
I copied the exe(or the other extensions) and then when I copy that file into my desktop using a memory stick and then execute the program, I get the same message" application cannot be executed..."
I am in a very bad state and any help would be appreciated. I have a Mcafee anti virus running all the time, but I believe that was completely useless.
Any help would be greatly appreciated.

Thanks!

In safe mode, I installed mbam(malware bytes anti malware) and ran the software, it detected and removed three infections, but I still get the same problem when I login in normal mode.

Are you sure its a virus? Something could of messed up the registry. Do a system restore in Safe Mode to when it was working. Then download Avast or Avira free anti-virus. Do a scan on strict mode to find any thing that could be causing it.

You are right. Even I believe it is a messed up registry.
For example, when I ran Malware Bytes Anti Malware, it found 1 problem, and in the log it claims
"
Registry Keys Infected:
HKEY_CURRENT_USE\Software\avsoft (Trojan.Fraudpack) -> Quarantined and deleted successfully.
"

If I run the scan again, I get the same message, so I believe the Registry Keys Infection is not fixed.


Thanks,

Go to this link to create a Rescue CD or to this site to create a Rescue USB. Carefully follow all the instructions for whichever method you choose.

Thanks SuperDave. I will create a USB right now. One clarification though "My infected system is running on vista, but the computer I am accessing the internet is a library computer running XP. By creating the USB on the library computer, will I be able to use it on vista?"

Shouldn't be a problem.
