Browser Toolbars – almost malware?


"In a previous blog post we wrote about the statistics from avast! Browser Cleanup. These statistics have become even worse:

  • More than 1,000,000 (one million!) browser add-ons are available for the three main browsers
  • More than 82% of all add-ons have a bad or very bad rating from our user community
  • Two thirds of all add-ons in our database are from only three companies
  • We see around 30,000 new add-ons per day of which 90% have a bad or very bad rating

As we can easily see the numbers are still rising. It’s now time to share some more details about the bad add-ons we’ve noticed so far.

As already mentioned in the last blog post, we analyzed many of these add-ons in order to learn how they behave, how we can remove them, and what we should expect in the future. During this analysis it became clear that the bad add-ons are even worse than we initially thought. In fact, a high percentage of add-ons installed on our customers’ computers behave similarly to malware. The common name for such “programs in-between” is grayware. You could also call them “Malware with a EULA”.

One of the most interesting (or rather, scary) features of grayware are the techniques used to prevent removal. Some of the vendors are very creative..."
