"June 13, 2002
First Reported JPEG Virus Found
By Gretchen Hyman

The emergence of a new virus that infects JPEG files was announced Thursday by security firm Network Associates (Quote, Company Info) and other antivirus companies, which received the code as a possible warning of things to come from its creator, who has requested anonymity.

The W32/Perrun virus, as it is now being called, extracts data from JPEG files and then injects picture files with infected digital images. A fair warning to those individuals who are fond of sending multimedia files to friends and families.

What makes Perrun so remarkable, according to security experts, is that it is the first viral program with multiple parts and the ability to carry viral code from programs into data files. Until now, data files were relatively immune to infection. Not so anymore, say experts.

Typically, the virus arrives via email or a floppy disk as an executable file, and so the standard warning against opening programs sent as attachment should once again be enforced. The contaminated file unleashes an extractor virus onto the hard drive and when a picture file is accessed with the .JPG extension, the second part of the virus strikes without notice to the sender or receiver of the digital image file.

The good news is that security experts think Perrun can easily be thwarted in its current incarnation and at present it cannot travel via mass emailings. Although with an upgrade it could easily become more destructive and pose a serious threat to PC users.

Computers running on Microsoft Windows are particularly vulnerable to Perrun, say experts.

Vincent Gullotto, antivirus researcher for McAfee Security was quoted as saying that Perrun is indicative of a very destructive pattern in the development of viruses and that it could be a sign of things to come for the exchange of JPEG files."

A decent virusscanner will find a possible jpeg-virus, besides that the security-risk has level "low".

Because you have already explained that your PC is scanned by several (online) virusscanners, and there are no positive results, I assume that you don't have to worry about a virus.

 

Hi Melanie

If I understood right your pix are visible on your hard drive but not on net. Not a virus, more like messed up net browser, happens with M$....Haven´t you tried to fix your browser yet:
1. click "start"
2. settings
3. control panel
4. "add or remove" icon
5. highlight your browser on the list and click on remove button
6. it asks if you want to remove or fix, select fix
7. you are able to choose which features should be fixed, as well you can select autom fix( recommended in this case )
8. now it downloads all damaged partitions if needed and do as it says including possible reboot

I hope this will fix your picture problem, it is pain when that picture failure happens

regards ~Ari~

 

Hi guys:

I had this happen ONCE to me a good while back on another system.
It would not open and if it did, it was *fuzzy* pixelated like it opened way too large for the resolution size [Like you can do in Photoshop, enlarging an image above its resolution]

I had no idea what/when/where/why it happen.

The *fix* that I did was to open Windows Explorer
Tools/Folder Options/File Types/select JPEG/Advanced/then click Set Default OK'ing all the way out.
I had to do this 3 times as there are 3 JPEG listings on mine [JPE, JPG, JPEG]

Now, this worked for ME, it was a desperate stab in the dark but hey I never had trouble again.

This may/maynot have anything to do with melanie's troubles, but worth a shot.

Cheers, TAS

 

is it possiable you changed your screen resolution?

right click on your desktop, then select properties, then settings asee what the resolution is.

800X 600 ect the larger the number, the better the quality image.
