Today we will be releasing a new database that is optimized for the latest builds of Malwarebytes' Anti-Malware. This will result in a significant decrease in fingerprints in the Malwarebytes' Anti-Malware database. We are merging certain fingerprints with others that are much more accurate and will last longer.

This optimization will result in a slightly smaller database file, slightly faster scan and protection module, and decreased memory usage between the scanner and protection module.

This type of maintenance will be performed a few times per year just so we keep a quick and effective scanner and protection module.

Many security companies claim that more fingerprints is better -- this is not the case with Malwarebytes' Anti-Malware. Our product can detect a whole infection with just one fingerprint, while other scanners may need hundreds!

Lol it's fast even without the database optimization

Malwarebytes is the best malware protection application in the world

Marcin,
Is that in defs 2573 ?

Great news! I was wondering why the database shrunk by about 100kb lol. Thanks for all your hard work!

You must be trying to fit it on a CD or flash drive .

This " optimization " makes quick scans longer than before. Didn`t tried a full scan , but probably the same ...

Actually, I just pay obsessive compulsive attention to every single kb of info that enters my pc.

I can relate, I'm a bit OCD myself .

any improvement is good news.

(think we all are in some way exile.)

Less ways to detect something is never better.
I don't run security products for their speed or memory usage ... i use them to detect security problems.
Bad idea (IMO).

At least there isn't half the spyware problem today that there was 3 or 4 years ago.

Hello,

this database optimization looks like redundant contents removal, more than less ways to detect malware, in my opinion.

Actually there are about a thousand more problems around now -
It is just that programs like MBAM can get them quicker and better than ever before -

What we do is the best of both worlds though . Better detection and faster . New tech makes old defs worthless so why keep them ? The newer stronger tech steps in front of the old defs so they are not even used , that is why they get deleted .

1.41 has an additional move in this direction and we are expecting some mass pruning of obsolete defs .

BTW , any app that goes on and on about number of defs like its a good thing is deliberately misleading you into thinking that def count matters in any way at all . I will give you a perfect example :

http://www.malwarebytes.org/malwarenet.php...=Trojan.Vundo.H

Those 55 million hits correspond with exactly 0 lines in the DB . 10 years ago that would have required a huge number of defs but those days are long gone as better tech trumps defs count in a big and growing way .

What does this mean?

[nosirrah]

Is "a" detects what "b-z" detect then "b-z" get deleted . There is no reason to have 50 things detecting the same malware when 1 will cover the identical infections .

@ Nosirrah

Thank you! That answers my question

[exile360]

Heuristics=win ! That's why MBAM is so effective against 0 day threats.

[swagger]

This is good, useful information. Thanks nossirah.

@exile, could you elaborate on 0 day threats?
