I've said it before, and I'll say it again:
The ONLY purpose Internet Explorer serves, is to download Mozilla Firefox.
I subscribe to Bruce Schneier, leading expert on security. His articles and publications are always well written, and he brings so much to the table in terms of security. Well, the latest entry on his blog is a link to an interview done with an Adware programmer. As you read the article, it's clear that Internet Explorer has some serious flaws, and these programmers are taking clear advantage of them. One might even go so far to say that Microsoft is aware of the holes, and turning a blind eye as they have an opportunity to make money on security software. At any event, IE is a serious security flaw, and anyone or any company even halfway serious about malware should take a second look at the flagship browser, and find an alternative.
Of course, we've been saying this to family and friends over and over and over until we're blue in the face, but they aren't listening. Maybe this article is good ammunition to have at your disposal. Good read.
