Probably unknown ...
NOD32 antivirus system uses a unique implementation of heuristic analysis, which can successfully detect many new viruses and worms as soon as they first appear. The heuristic analysis protects the users of NOD32 in the most critical time of infection spread - from the appearance of the infiltration until the release of antivirus updates. In such case, NOD32 will mark the new found infiltration as "Probably unknown ... virus" followed by detailed description of the infiltration.
Most common types of infiltration are:
- NewHeur_PE virus
File marked as "NewHeur_PE virus" was detected using broad heuristics because it contains parts of code typical of worm infiltrations spread over the internet. Using this method NOD32 was able to identify worms Win32/Zafi.B, Win32/Mydoom.R, Win32/Bagle.X and many others.
- Win32 virus
File marked as "Win32 virus" was detected using heuristics because it contains parts of code typical of viruses that attack 32-bit operating systems of the Microsoft Windows family.
