Rated 5 out of 5 stars

@sickdog: you downloaded the wrong Bitdefender. This, is a very small, in browser plug in that does exactly what it says. It quick scans for malware, virus, etc, on whatever page you happen to be on or are going to. If it pops up with a bad bug, then you use your BIG anti-virus client to get rid of it. It's more of a warning device, NOT an anti-virus and virus removal program, but they do have one that does come with a free trial, before you purchase, just like all the other ones that you actually PAY for. If you're looking for completely free, then MS Security Essentials, at least for the rest of this year, is totally free and does the job pretty well, although it doesn't dig out the scum the way malwarebytes does. Btw, they have a free version too, but if you want the full version you'll have to pay for it after the 2 weeks are up. The free version, imo, does all I need it to do: tells me if I've got a nasty on my pc, and quarantines until I tell it what to do: get rid of it or ignore it. Bitdefender's little red button, though, is some peace of mind I like having on hand to quick scan before I download or go to a new sight. It works, period.

This review is for a previous version of the add-on (0.9.9.119.1-signed.1-signed).
