LOL! Don't worry about the nick name, it doesn't reflect my intelligence (thank god!).
HERE's a quick story about how I got that nick name.
It doesn't seem as if you've got the professional version of Photoshop installed, more like a free version that comes bundled with certain things (like cameras, scanners etc.). If you don't need it, don't use it. Chances are that it was sucking up all that processor speed becuase it was either looking for an update or scanning your computer for images that it could open (.jpg, .gif, .tif etc. etc.).
HERE is a list of free computer editing programs that you can use. As for storage or "photo management", I'd just recommend that you
copy the images from the camera to a folder (labeled by date, event or something that you'll recognize when searching for images),
verify that they are there on your hard drive, then delete the images off the camera itself.
If you do want this adobe software on your computer, you could download it again, then check the options for a way to shut off the "auto search" and/or "auto update" features. However, I've always had a huge heartache about programs that just install themselves without asking my permission....I figure if they don't ask to be on my machine then I don't want them there. If it were me, I'd use one of the freeware programs listed to edit my photos rather than a program that downloaded itself on my computer.
Also, just becuase you've got programs downloading themselves on your computer, I'd strongly recommend that you follow these instructions HERE and just do the scans (no need to submit a HJT log unless you think that you're still infected, or if you just want to make sure that you're not infected with something that the programs might miss or something that keeps re-installing itself). Just some friendly advice!
Hope this helps, and please let us know if you have any more questions about anything at all!
