Corporate IT departments should be pleased with new security measures in Windows 7, but consumers are still at risk of getting hit by malware despite changes in the UAC feature.
Most IT techs know good and well that the people at microsoft put security in the back burner. Its about like the limited file sharing permissions, and the hidden administrator account built into XP.
Malware is still problem, even with vista. I still see vista computers infected with all kinds of malware/scareware on a regular basis.
I think when there are computers, there are malware.
And, no one should rely on the built-in features come with OS to protect their computers from being affected. IMO.
