we use Firefox and hubby was just on Ebay today- so far so good.

We use Zone Alarm Extreme Security full time & the WOT browser add on for extra internet security & also run other anti virus scanner programs occasionally if the computer starts acting odd or slow.

It's good to have a second AV program installed and set up -but only run it manually as needed.
Don't depend 100% on a single product to catch all the bad things.
