6.37 Product update
-------------------
General notes:
- This is a 'preview' release of TBAV 6.40, which will have a
completely new designed heuristic engine.
The actual reason for this preview release is that we added
detection for two currently quickly spreading viruses: NightFall
and ByWay.
TbScan:
- The heuristic engine has been redesigned! Detection rate has been
improved, while the false positive rate has been significantly
reduced. Without option 'heuristics' TbScan now detects about
80% of the viruses! If you specify option 'heuristics' (the so
called 'paranoia mode'), TbScan now detects about 95% of the
viruses! The default heuristic level should never produce 'false
positives' anymore, and the amount of 'false positives' in the
paranoia mode has been reduced to 20% of what it used to be.
The next version of TbScan will be a major new version with
heuristic capabilities that are even better than it is now.
- To ease testing of the new heuristic engine, we added a new
option 'hrtest' that causes TbScan to disable signature scanning.
Viruses:
- Added signatures:
ByWay
NightFall
