Antivirus that create checksums

What av create checksum databases of scanned files? I heard Pc-cillin does this with "Turbo Scan" to make scans faster. Is this a common feature with today's scanners?

 

As far as I know for example the combination of Dr.Web and ADinf32 can do it.
For a thread about ADinf32 see:
https://www.wilderssecurity.com/showthread.php?t=72131

 

NOD32 and KAV do this, although I don't know if NOD32 specifically creates checksums, but the effect is the same (doesn't scan the same file again until it's changed).

 

Norton has a setting to do this also if wanted.

 

As a side-note:
(and once again.............)

checksums need to be stored safe (!!!), otherwise it makes no sense.....

 

WinHKI Antivirus. i'm not sure if there's a free version or not, it polls the system every 30 seconds which you can change if you want to.

Kaspersky also does that. Not exactly sure for KAV 5 but KAV 2006 does it for sure (scanning plus in Proactive Defense module)

 

Apparently they have a free version too.

PS. I'm sorry, this may be an other product than an av!

Hi,

Solo antivirus integrates an Integrity Checker:

There is also "original AVs" like Viguard, Invircible and Integrity Masters wich are based on Integryty verification.

Thanks for the replies everyone. I'm interested in how this all works. Does KAV and others take a long initial scan to calculate hashes for each file then every scan after that recalculates and compares, or does the resident guard actively monitor for file changes? For WinHKI, I think it seems to be more along the lines of intrusion detection, but still may be worth trying. Thanks for recommending!

 

Yeah if you enable this in NOD, the memory usage will drop to around 4kb total (instead of the normal 17kb).

 

How do u enable this in NOD32?

 

AMON > Setup > Options > Optimize scanning.

 

Thats already enabled, still my mem usage is around 17-18 MB!

 

It will be if you use alot of streams (vidoes, music etc.)
If you look at AMON you can see which file it keeps scanning - You can then exclude it or live with the 17kb
And also, it takes an hour (maybe more, maybe less) to drop to 4kb.

 

OK! Thanks. Though im not using any streams, neither AMON is scanning something, but then, i can live with the 17 MB. Hehe. BTW, i think you mean 17 MB, NOT 17 KB!! LOL!

 

Yes I do 17mb, my bad.
Just for show, I have enabled the option and streamed some music for about an hour using Winamp, and if you don't stream anything it will drop to 4MB total. Now it's around 8.5
