But even after a fresh install of windows, my explorer.exe crashes even when I attempt to open even a text file, no matter what program I use to open it.
Most of the time I can run an .exe file in explorer safely, but running pretty much anything else comes with the risk that explorer will crash (Data Execution Prevention- To help protect your computer, Windows has closed this program) and I'll have to close it (and the meddling DrWatson) and reopen it in task manager to get my computer back. Sometimes I will just get the error popup and still be able to shunt it off to the side of the screen and continue with what I was doing (and I can open text files indefinitely when I do this), but sometimes it just closes explorer right out.
Given that I tested this on a fresh install, I'm -pretty- sure it's not malware or anything like that, and I can identify pretty much every line that HiJackThis generates. Can anyone give me an idea as to what's going on?
