Internet Explorer has a major major flaw in it, i should know i was hit by a trojan last week, kept redirecting my page to about:blank and loads of popups, tried all sorts, hijack this, adaware, spybot etc and i couldnt remove it.
I sorted it out basically by restoring my pc to its previous factory state, essentially removing everything off it since i bought the machine. I then dumped IE and am using Firefox now.
Microsoft are in a rush to get the major flaw fixed, however most security companies, government related agencies etc have advised surfers to not use IE at all until the issues are sorted out.

THE US GOVERNMENT has sent out a warning out to internet users through its Computer Emergency Readiness Team (US-CERT), pleading users to stop using Microsoft's Internet Explorer.
Following a malware attack last week which targeted a known flaw in IE, like so many other attacks, the US-CERT recommended using alternative browsers thanks to their increased security. Microsoft is hurriedly trying to increase IE's security with the Windows XP Service Pack 2, but it's not fast enough for many.
In a vulnerability note released by US-CERT, it says "there are a number of significant vulnerabilities in technologies relating to the IE domain" and that "it is possible to reduce exposure to these vulnerabilities by using a different web browser." Well, they're right.
The latest "extremely critical" IE bug has still not been patched by Microsoft."
