Actually among most technical forums the majority of people who have had a look at SP2 refuse to use it for its huge security vulnerabilities. You're no safer than you were before, you'll just be hit by more recently developed techniques.


Here's the article I've seen the most(abbreviated)-

"SP2's Windows Security Center, the dashboard-like console that monitors and reports on the status of various security defenses -- from firewalls to anti-virus software -- can be spoofed by hackers into displaying false information, such as an enabled firewall or a even a totally bogus anti-virus package supposedly protecting the PC.

Security status could be faked, said the researchers, by a number of possible exploit avenues, including the drag-and-drop vulnerability in Internet Explorer that was made public last week. The possible goal by hackers: disable defenses but at the same time remain under the radar."
