This is correct. The primary third party engine is Capricorn (Avira) and it does most of the heavy lifting for on-demand scans. Note that their in-house engines are really good at Office97 macro viruses and it tends to mop up most of those kinds of threats that Avira misses.Avira engine would be the Capricorn? and from what I researched now the others would be these
- Hydra: Script based (heuristic) AV engine.
- Virgo: Certificate whitelisting engine.
- Lynx: Cloud scanning (sandbox) engine.
Also worth noting, DeepGuard (behavior blocker and memory scanner) is in-house and is one of the best dynamic protectors in the business. And FSO (F-Secure Online's cloud) is pretty powerful too, it's a hash based cloud scanner. It is pretty effective against zero days, but recently it's been clouded (no pun intended) by them auto-blacklisting all Abuse.ch and auto-sandbox-analysis (like JoeSandbox) samples.
