I recently experienced some trouble with a nasty trojan. First it was one thing, then it was another. It intercepted my browser functions and my virus scan, modified a lot of my Windows settings and kept me from being able to run Windows Update. Happily, I can say that I believe it to be cleaned out of my system and I was able to get the latest Windows Updates. (I still can't use McAfee virus protection, the trojan really hated McAfee for some reason.) One thing remaining is that my Windows Sidebar Gadgets in Vista aren't working correctly. I can load the Clock Gadget, but its just a black circle with no options to change it. The few other Gadgets I can load just look like blank spaces. I have no idea what is wrong at this point.
