How does avast! Antivirus work and detect malware?

[sk3llgamerZDay]

Just a curios person trying to build my own antivirus and I currently use Avast! I was wondering how those MD5 antivirus's (or avast!) detect malware. I know of Violasoft which is pretty crappy but I just want to create one as a experiment. I found a open source project on YouTube but the code doesn't make any sense to me. I've been programming in vb since I was 8 or 9 and would really like to advance. Should I find another easier project to do or can someone try to tell me not how to code them but just..how they work. Thanks ~ Flames

Well, first it installs it on your system, and then it finds it and prompts you.

Hang tight. Someone surely knows.

"The huge numbers of CommunityIQ member's create a "cloud" of sensors that gives us a real-time snapshot of the threats posed by websites across the internet," said Vince Steckler, CEO of avast! maker ALWIL Software. "Our cloud gives a huge time-sensitive amount of data on the state of malware and viruses across the web." Globally, the 1Q'2010 set of data includes 252,000 infected domains which were visited and identified through 11.9 million visits by CommunityIQ members.

Thanks I was just curios. P.S should I focus on something smaller than an AV? I heard it costs a lot of money and time. Maybe simple .BAT programs to kill rouges and crap? Sorta like RKill? Maybee..?

You would think that it would be less tedious.

Im thinking something a little smaller might be a better undertaking.However don't let anyone tell you you can't do it,even if you give it a try and fail I am sure you will have come away with more knowledge.
