What is the difference and the advantage

Maybe this question is asked before and answered but lately i have been wondering about the advantages of cloud and normal (sorry for the non-tech term) antimalware technologies or products. I am not asking which but rather what

 

advantage: with a well-engineered implementation, a newly detected threat can quickly be identified by all clients associated with the cloud within a very short amount of time, without needing to push signatures to those machines.

disadvantage: a disconnected client may potentially have issues detecting emerging threats. the same holds true of most signature-based av applications, since they won't be getting new definitions.

(simplified, but you get the idea)

 

Just an insight: aren't new and emerging threats come from the Internet as well?

But yeah, I totally agree with m0unds on this.

 

Well, i prefer the avast! approach that will be used when they go cloud tech.
They will use same update system as they do now, which will be assisted by cloud technology. So you can get best of both worlds.

 

advantage: When somebody of the herd (in the cloud) is atacked by a lion, you will get protection for that specific lion or lion family group, so nobody else in the herd gets infected (attacked).


disadvantage: Is merely for the one attacked by the lion. For removal one of the most effective disinfection ways is to start in safe mode (only loading essential services and drivers). As long as Cloud AV's don't offer Safe-boot scans (e.g. like Avast) they allways face the challenge of ring-0 fights. Malwares are good Ring-0 cage fighters (better than AV's generally), often disconnecting the client from the cloud permanently (same way lions isolate their victim out of a herd and we all know how that ends up: eating the bowels first while the victim is still alive).

Emisioft's Emergency disk contains an analyser (Hijack Free) and a removal tool (Blitzblank) as a good practise example. Panda should include something like RegRun or Blitzblank to compensate for the cloud weakness.

 

If a duck floats on water and it doesn't rain then the lake might dry up. If that happens the duck can't swim in the water anymore. So it either has to wait for more rain, or fly off and find water elsewhere. Unless it's injured and has to walk. If it's not to far, and goes in the right direction, it should find it sooner rather than later, and be OK
