I recently installed Internet Explorer 7 Beta 1 (7.0.5112.0). But even before I did I think I came across this problem before - on each startup of the Internet Explorer, the security level (Toos - Internet Options - Security <tab>) is deactivated totally for the Internet, Local intranet, Trusted sites, and the Restricted sites. The whole lot. Even though I'm running Ad-Watch and NOD32 all the time on the computer, doesn't the inactive security level post a threat?
I do scan my computer with Ad-Aware, Ewido, and NOD32, nothing was found. Still I'm wondering - could this be a worm or something that's turning off my security level in IE?
