Avast needs Herustics
« on: May 24, 2009, 07:44:33 PM »
If Avast buys or adds a Herustic product and adds it to there antivirus products it could detect more types of viruses and a lot of people would use it. I really this avast is a good Antivirus :) but it needs Herustics.

Well with a 99.2% detection rating in some AV tests, avast doesn't do so badly for an anti-virus supposedly without heuristics.

In fact by many interpretations avast could be considered to use heuristics, in the form of generic and algorithmic signatures.

It also uses heuristics in the anti-rootkit module and Internet Mail provider.

This will be further refined in avast version5.

Define Heuristics...
And you'll see that avast already has it as David said.
The overall detection is what counts, not the advertisement of the products to sell...

What I mean is that in the On access scanner each of the providers could use Heuristics. If this happens in a newer version of avast, Maybe avast could have a higher detection than Avira and might be able to detect more than 99%.

It's already there with generic signatures and algorithms detection...

I vote for ALWIL guys to just add "Heuristics" checkbox, even of it does absolutelly nothing. But it would calm down everyone. ;D

-= eh..?  ???

-= Somehow, I'm still not-so-sure if heuristics will be a help for avast or a cause for more FPs.. I'd better wait & see..

To me, the main point of this thread was made by Tech, who said "Define Heuristics."

From a software writing point of view, I wouldn't have the foggiest. And I think that statement was made for other users in the same position, who might be prepared to buy the sales hype. (And in some cases, it probably is hype.)

99.2% with/without heuristics^^(in any case)--i dnt know for sure^^

Thats big enough for a FREE antivirus^^

Also, i think the heuristic scanning will increase the rate of false positives^^(just maybe)^^--my opinion only^^

Well, antivirus can also have proactive features (heuristics) that are not even controlable by user.
There is already a number of these features, but there are more coming with version 5.

I could be wrong, but I think they will assume avast 5 has proactive (heuristic) methods clearly.

Hi all!

Define heuristics?

Generally: Heuristics = guessing.

Guesses can be good or bad, well or ill informed, right or wrong.
Guesswork is often a useful thing but you wouldn't want to bet your life, or your life savings (Did I hear someone say; 'Global Financial Crisis'?), on it!

Now back to avast!
If avast! is to have heuristic analysis in the Standard Shield, it will need to be very good heuristic analysis. The word 'heuristics' is not magic. (BTW, love the fake slider joke ;D.)
I think the semantic issue stems in part from when ESET (a company for which I otherwise have great respect) began using the term "Advanced Heuristics" as a label for what they describe in detail as behavior analysis.
There is a way that seems right to a man,
       but in the end it leads to death
.” - Proverbs 16:25
