Remove Browser Defender 3.0 by Threat Expert

Browser Defender is a utility developed by PC Tools which protects the computer by providing informative assessment of websites and the possible dangers they pose, thereby allowing the user to make better informed choices when browsing the Internet. A green, red or yellow rating let the user know immediately if, in ThreatExpert's opinion, the website is safe to visit, harmful or needs to be visited with caution. If the website is not amongst the crawled domains, then a grey rating will be shown.

The most common release is 3.0.0.312, with over 98% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The program adds a toolbar to Microsoft Internet Explorer. The primary executable is named PCTBrowserDefender.dll. The setup package generally installs about 15 files and is usually about 14.86 MB (15,582,840 bytes). The installed file PCTBDUpdate.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered.
