I noticed that every time I start windows smart security quarantines something that I don't know what it is. I also found out that it only happens when I connect to the internet. It started happening yesterday and I don't really remember downloading any weird files, here is a screen shot of the file it deletes. http://img100.imageshack.us/my.php?image=weirdir7.jpg Also I'm running windows Vista home premium if that helps.
1 thing to check is to see what your home page is set to. This site is listed as a BlackList site, meaning it contains malicious files that will try to download themselves just by visiting it. If, per chance, you got something on your system before ESS, it could have changed your home page. Just a thought
