I just typed a long post that somehow got lost when I hit the post button,

so if this shorter one doesn't make sense, ask questions and I'll try and clarify.
I have a folder on my desktop with a bunch of shortcuts in it. For the last week or so, it keeps changing the view so I see the detailed list of files and not the icon view I'd like. I change it back to the icon view, but a while later, it'll be back to details.
This started after I cleaned up my system with CWShredder, seek & destroy, adaware, Hijack this, kill box and all these other programs after I ran an .exe with a trojan. The problem didn't happen while I my computer was infected. It only started after I cleaned up my system. Those programs like to delete a lot of things and I'm afraid something got screwed up in the process.
Oh, and now I sometimes get Direct Show errors when I go to webpages with Media Player content that's embedded into the webpage. This also only started after cleaning up my system.
The only other thing of note is that my firewall reported that whitehouse.gov was scanning my ports the other day, but right now I'd just be happy to get my icon view to stick. Can anybody help? TIA
