AV is based upon what is known and then an update. I for the likes of me will never undrstand why anyone would spawn a billion dollar industry based upon a fault in the OS. Yet that is what someone who releases a virus does. And it infects computers and everyone makes money but the virus author whom is left with bragging rights...wow. People make money on this stuff and wait until the next, they want to be given the problem and well guess what you have to pay for the answer in the next upgrade, because they are the only one's to solve it.

Same for spam some of the first spam I ever got was off of Hotmail (M$), AOL, and Yahoo and for years they ignored the complaints from everyone. Now they are going to fix the very problem they created? Guess what yep they will and it will cost you $$$ in a software upgrade. Yet I went back to just the basics that were about oh 20 years ago and my open source AV scanner caught the latest Baegle virus before it was even listed by the AV people, I nix and clean the spam, program cleans out about 95% of the one message per 15 seconds they send to my network. Total cost for this endevor was about 500 US dollars, and what my company saved by not upgrading under my reccommendation Exchange and AV software.

Do I feed AV people info? Hell NO if their products are so great they on the bleeding edge not the cutting edge?. But I do support and whom I work for now support Open Source, why because they are cutting edge. It is just old hat stuff no bells or whistles just works because of the people behind it. Only place 6 months from now you will find windos in my office is the desktop, and even that is just for now.
