Does anyone have specific knowledge of a Windows virus that modifies/eliminates the association of image files on Windows?

I am helping in the administration of a Windows network and I am getting many complaints from a certain group of users claiming that they are not able to open .JPG files anymore (they all use to be able to open them without problems). Their Windows system (Win95) does not recognize the format and does not associate it with any programs. If I take the file to another PC on the same network (but in another group of users) it opens without problems.

Since the complaints are coming from one group of users I was thinking that maybe they have been infected, through an email message addressed to the group, by some virus that got away from our antivirus software (NAV).

By the way, I have tried to force file associations on these Windows PCs, and I still can not open these image files.

ahh yeah i had that problem too.. its not a virus or alteast less likely to be a virus.. its just a registry error..

go to regedit in the HKEY_CASSES_ROOT folder.. look for the .jpg folder and change the "Value Data" of "(Default)" to "jpegfile" without the ""

that should do the trick

Sorry couldn't reply any sooner but we had a prolonged holiday in Brazil and I traveled for a couple of days.

Sonic, I tried to follow your sugestion but the "Value Data" was already set to "jpegfile".

Darkadon, I didn't exactly install any new image programs but I did try to reassociate the files through the Folder Options of Win95 and using the old File Manager interface, without any success.

Any other suggestions? Anyone ?

I have a similar type of problem. My win explorer window has VIEW AS WEBPAGE enabled but i cant view the thumbnail/preview of jpeg/jpg files though .bmp/.gif files are visible. Is it same as MBrito's or something else
