Database Optimization


Recommended Posts

  • Root Admin

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!

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.

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 .

After a little research on my phone (not much, just googled it), I found the description for a zero day threat...

A zero-day (or zero-hour) attack or threat is a computer threat that tries to exploit computer application vulnerabilities that are unknown to others, undisclosed to the software vendor, or for which no security fix is available. Zero-day exploits (actual code that can use a security hole to carry out an attack) are used or shared by attackers before the software vendor knows about the vulnerability.
