SDAT's massive size

Hey guys! Any news when the sdat's size will be lessen to uhmm let's say 10-20MB like 4 or more years ago?

I always use this for a more deep scanning (safe mode and cmdline scan) and unlike before it's quite easy to provide this to our end-users via email.

Re: SDAT's massive size

Not only do the definitions take up much more space, but the SDAT's also include software to detect and install the correct files for mulitple versions of VirusScan. I'm also guessing the SDAT has both the older and newer virus definition file formats.

Re: SDAT's massive size

The SDAT contains both V1 and V2 versions of the dat files as well as engine files for Windows (and some special engine files for certain Windows scanners). V1 dat files are end of life 31 March 2010, at which time the Superdat will probably drop by about 50% or more.

I know McAfee are doing stuff in the background to try and reduce the size of V2 dat files, but unfortunately I suspect that things aren't moving very fast with that attempt due to the number of new threats that they see each day.

Re: SDAT's massive size

I'd also guess that one issue preventing them from reducing the size too much is false positives. Reducing the size would probably mean less detail about a threat, and a greater likelihood of of a flase positive.
