There was a folder called "Dennis" in my "documents and settings" this morning. I never created an account with that name, so it got me kind of scared.
I scanned and have no viruses or trojans. I found the folder appears when I run imgburn as administrator (I only use administrator rights with runas, my account is limited) and I change the autoplay setting in imgburn's options. I did this once because I wanted to get rid of the "burn with imgburn" option when I right-click an image file (something I failed to do even with shexview btw, annoying).
What kind of nonsense is this creating a new folder there, I thought I had been hacked an someone made a new account! I used the search here and I googled before posting this, nothing.
Edit: What's in that folder is like this... Dennis->Application data->Imgburn->imgburn.log (file). That's everythings that's created.
