This free update now supports the newly released FireFox Web browser by Mozilla and expands its spyware profiles. Users can access this free update by using the EasyUpdate feature in the software. Internet Cleanup contains powerful features: -- COMPLETE SPYWARE PROTECTION -- Internet Cleanup 4 (IC 4) detects and can remove the latest ad-ware, key loggers, which record keystrokes and can uncover user passwords, a wide variety of Trojan horse programs as well as other types of spyware. IC 4 protects against the newest spyware programs with routine updates to give users the latest security. -- SEE WHO'S WATCHING YOU! NetBlockade(TM) -- Manage and block cookies, Web bugs, ad banners, and pop-ups. NetBlockade's Trace utility performs a "Who is"-type lookup so that users can find out who is trying to spy on them. -- LOCKING MECHANISM PREVENTS SNOOPING -- IC 4 has the ability to protect user-specified folders and files by locking them so other people cannot open them or view their contents. This capability offers users the assurance that their private information remains confidential. -- PREVENTS UNAUTHORIZED ACCESS -- IC 4 enables users to block applications on their computer from use by other people who gain access. This is extremely useful for computers that are shared. Now the user can password- protect any application they don't want being used. This is a great feature to prevent the kids from getting into financial applications. -- HELPS NETWORK ADMINISTRATORS -- Clean up files across networks. IT managers can run IC 4 on a networked PC to scan remote drives for temporary Internet files such as recently visited sites and other common files, enabling network administrators to protect the privacy of all PCs on the network. -- WORKS WITH MORE BROWSERS -- IC 4 supports Internet Explorer, Netscape and Mozilla browsers, including the new FireFox(TM). Internet Cleanup 4.0 protects users' privacy by erasing their Internet data trail and permanently removing tracking devices left on their computers by spyware. IC 4 allows users to determine their level of banner ad and pop-up blocking. With Internet Cleanup' Statistics Report, users know exactly what spyware is present on their PC, the number of unwanted cookies and history files, their cache size, Active X controls, recent list entries, and more. Internet Cleanup effectively removes spyware and stops pop-up ads and web banners -- protecting privacy.
