Javacool Software LLC, Releases an upgraded version of the company's popular SpywareBlaster(R).

With over 50 million free downloads since the company's launch in 2002, Javacool Software offers a range of free privacy and security software products used by home and small business computer owners worldwide, along with other services for enterprises and networks.

Unlike other subscription or free anti-spyware and anti-malware software, SpywareBlaster focuses on prevention. It protects against stealth downloading of spyware, adware, browser hijackers, dialers and other potentially unwanted software. And unlike other programs, the performance-friendly SpywareBlaster does not remain running in the background, avoiding drags on a PC's operation.

SpywareBlaster coexists with other security software to provide a "layered defense" against multiple threats. It prevents the installation of ActiveX-based spyware and other dangerous programs, blocks spying and tracking via cookies, and restricts the actions of potentially threatening Web sites.

The new version 4.2 of SpywareBlaster features improved Windows 7 support, faster updating worldwide, support for the Internet Explorer 8 and K-Meleon browsers, interface improvements and numerous other enhancements.

PC World magazine recently named SpywareBlaster as one of its '8 Great Free Security Tools.' Noted the report: "With this downloadable antispyware utility, you can make sure you don't get infected in the first place rather than scanning for and killing spyware after it hits your machine. It works differently from most competitors by restricting the actions that potentially dangerous Web sites can perform when you visit them. It also protects against dangerous ActiveX controls, and keeps tracking cookies off your PC."

Javacool Software offers a SpywareBlaster AutoUpdate service to download new versions when they become available, with automatic database updates, easy multi-user coverage and technical support.
