Hello,
I have been having this problem from 3-4 days.I am unable to run any program except vlc player and mozilla 3.0.7. All the shortcuts have been converted to lnk files.Even IE-8 has crashed. I cannot even run a virus scan as no program is working. I cant open command or cmd from run. Actually from nothing is opening from Run, a dialog opens saying windows cannot open this file and asks for web help which it does not take or to choose program from a list for every program I try to run. Not even Regedit is opening. I cannot even play a dvd. That day I was browsing a torrent site of which I dont remember the name. My kaspersky antivirus warned me of a trojan and I blocked it, but I think it was installed from there only. Please help. Any help will be highly appreciated.

I had this same problem and this fixed it. I don't know much but I know it helped me. At least try it. I spent hours trying to fix it and then found this. The stupid "choose program" box came up a million times.

Try this it worked for me. I hope it helps...

Not sure if this is what you have, as you haven't mentioned pop ups, but there's been an onslaught of rogue AV problems w/many of my clients lately (XP Antivirus 2010, Vista Antivirus 2010 and various similar names).

They auto install on your PC with no notice or consent, just by browsing certain sites without high security settings in your browser.

Generally you'll get pop ups stating that you need AV protection, malware has been found on your machine, etc.

I ended up having the issue you have (stemmed from the above mentioned rogueware).

The fix I used was manual (as I couldn't even get my AV updates or even get to the sites), but not too difficult.

1) Browse your PC and find your "regedit.exe" file (usually in C:\Windows)
2) Right click on "regedit.exe", copy, and then paste to your desktop
3) Go to the new "regedit.exe" file on your desktop, and rename it "regedit.COM"
4) You should now be able to douleclick on that file and open Regedit

*ONLY EDIT EXACTLY AS LISTED BELOW. ANY OTHER CHANGES MAY PERMANENTLY DISABLE YOUR SYSTEM!!!*

Navigate to

HKEY_CLASSES_ROOT\

expand that (click on the + sign) and scroll down to ".exe" and click on it

The bar at the very bottom of the window should show that you're on the location:
My Computer\HKEY_CLASSES_ROOT\.exe

The first value for .exe should be the follwing:

Name___________________________Type _____________________________Data
(Default)_________________________REG_SZ___________________________exefile

If it says anything else under the data column (for example "secfile" instead of "exefile"), you need to change the value back to "exefile"

You can change it by right clicking on "(Default)", selecting "Modify", and then deleting the incorrect data, typing in "exefile" and clicking "ok"

This will renable all of your .exe files.

Once you have done this, close out of regedit and delete regedit.com from the desktop so it can't be altered accidentally.

There will be cleanup that still needs to be done, but unless you're very familiar with the registry, it's best to use software.

The free version of Malwarebytes is always a good start.

Hope this helps :)

Hi, I am having the same problem,

I have just followed the above instructions and it won't open the file for some reason. I have changed it to .COM?

Thankyou
Ami

Hi Ami,

Are you accessing the Internet from the infected machine or another one?

If you can get to the net from your machine, then it's not the exact same problem, as to open IE or Firefox requires a .exe file to execute....so if you can do that you don't have the same issue.

Sality and a few other viruses disbale both .exe and .com extensions.

Just to double check, you changed regedit.exe to regedit.com correct?

1) Can you access Internet from your machine?
2) Are you getting any types of popups (such as security/virus warnings)?
3) When you change the name and double click, do you get any warnings or popups, or does nothing happen?

I need to know the answers to the above questions before I can give any other suggestions. :)

Heading off for a bit but I'll check back later this eve.
