Kaspersky Free is pretty good - and just as free as Security

When a user tries to download Kaspersky Free antivirus, they find that
they have downloaded Kaspersky Security Cloud — Free instead.

Since it is a cloud AV, does its malware detection level significantly
decreases when the host is offline? That's what happens to Panda Cloud
AV free. I've seen many detection tests showing Panda Cloud detected
99%+ when online, but only 66% when offline.

Be interesting to see how Kaspersky's free Cloud AV rates for its online
versus offline detection rates.
