How safe is a cloud based antivirus?

I've just got a 1year WSA antivirus for free and I intend to install it on my main pc.

Searching the "Help" I found out that WSA doesn't have a resident database and all file are scanned in the cloud.

How safe is to run such AV when all your files are "inspected" on the cloud and you never know who/what is on the other side of the cloud?

WSA = Webroot SecureAnywhere

Yep, got a PM from the OP. Another senior moment for me.

I'm not a WSA guru or even a user, but from what I've read about it, your files aren't exactly sent to the cloud to be scanned. Instead, WSA has a small resident engine on the local computer that analyzes the files, and which communicates with rules and reference info located in the cloud, to make its determinations. A lot of it is heuristics-based, along with a modest amount of signaturing. When your system isn't hooked to the net, the resident engine journals whatever goes on, so that once net connection resumes, it can roll back whatever has occurred should something be detected after-the-fact.

I won't use a cloud based only anti virus solution on a PC based system. Cloud assisted is fine with traditional signatures and heuristics.

So aside from marketing hype ("it's in the cloud") what's the advantage of such an approach? I'd think that storing definitions locally (i.e. on HD) would be faster.

I don't know a lot about it either, but 'sending files to the cloud' sounds like the absolute worst way you could design it, from the viewpoint of performance.

Well.....I install it!

I seems like , when you do a full scan , ALL your files will have MD5 determined and compared with the info in the cloud...

I other words ,the "cloud" will know each and every minute all what is in your pc... your privacy is gone but the scan, I have to say, is very fast and the foot print is insignificant.

I'll stick with "slow" scans thank you
