Choose the Program. What Program?

You have a file that's set to run automatically when you access the disk. It's probably a virus or a residue from a virus. Your anti-virus software may have taken out the virus itself but the program that makes it run is still there.

Open Windows Explorer and click on Tools/Folder Options, click View and select "Show hidden files and folders". Also un-check "Hide file extensions for known file types" and "Hide protected operating system files".

Next, click "Search" and type *.* in the search box. Select drive C: as your search location and click "Search now" and wait.

If you see a file like "autorun.info" or anything with a name like "autorun", delete it.

Let us know how it turns out.

Hi there Vulcan,

I did whats your instruction regarding this matter, but sad to say nothing happened.

I found also this morning that eventhough my 120GB mobile hard disk with 3 partition has been infected(1 of 3). I suspected last saturday that, it is virus because that time when am unpacking universal keygen(downloaded from net) my McAfee responded "trojan remove" i suddenly deleted the file. At that time this problem arises. Am start pulling my hair now, bout this problem.

Okay, I remember something similar happened to me a couple of months ago. It involved pdf files.

I was trying to open a pdf file and I kept getting the same message that you were getting. A virus scan turned up nothing and I tried opening a different pdf document which opened normally. My Acrobat Reader was still functioning so why was my computer asking what program to use?

I made a different search. I searched for all files (*.* in the search box). I was surprised to find that I had two copies of each pdf file that had names with three letters or less (I had files like CA.pdf, MA.pdf, etc). In thumbnail display mode, they looked different from other pdf files.

After checking that I could open the originals, I deleted the duplicates. The symptom disappeared. Apparently, a virus (which had been removed) had left a few files that would have triggered an infection. The virus had been removed but the files remained. Since the OS didn't have the file (the virus) that would open them, it kept asking for help in getting them opened.

I don't know if your situation is the same. You can try what I did. Good luck.

regards,

Vulcan
