I can guarantee it's a false positive, but I can understand your reluctance. If picwalker hadn't been abandonded, you could email the author about it. You could still try contacting the makers of your antivirus software about it, but I doubt it'd do much good. Pretty much your only choices are to take a chance or not risk it.
Cdisplay is an excellent archive viewer, I didn't mention it before because I didn't think it could do thumbs. I use it all the time for reading comic book scans. Cdisplay views the images from directly within the archive (it might create files in your temp folder, but if it does, it deletes them afterwards). With most archives it simply extracts the image you're currently looking at (and a little ahead if you have it set to), and leaves the rest untouched. Some formats however (like tar) it has to
open the entire archive. Needless to say, tar isn't a good format to use with it.
You can export images from an archive to a
file one at a time, just right click while viewing the image and you'll see an option to save image (you can save as
file, or to clipboard). It can't read PDFs though.
Cdisplay's author vanished quite a while ago, so developement on the official version is dead until he reappears. However, there are 2 unofficial versions. One is a minor update that improves the interface and adds a couple features, but is still essentially cdisplay. Unfortunately, the site for it is currently offline (
http://cdisplay.net ). The other version adds a lot of features, but changes the prog fairly significantly. It can be found at:
http://sourceforge.net/projects/cdisplayex/
