Zigar is right, no image file can infect your computer on it's own at the moment. There was a thread posted earlier about a virus ( http://www.antionline.com/showthread...hreadid=230234 ) which used hidden code in jpg's, but in order for it to work it had to catch the jpg when you opened it and see if it was infected. Without the program to catch and execute the code in the jpg it would be completely harmless. So unless it's a file with a hidden extension "*.jpg.exe" and your computer hides the ".exe" then then image itself should be fine, wouldn't hurt to scan it anyway though. To keep virii like Sircam and Klez out of your system keep your email client up to date, use one that won't execute scripts by default even, and keep you AV .dat files up to date.
