PC Doors Guard is a complete anti-Trojan solution for your office and home PCs. The program consists of three main utilities, which can provide you with stable and reliable protection. A Trojan needs to get through this three-folded barrier in order to infect your PC. While online updates keep PC Doors Guard up to date, the built-in heuristic analyzer can detect a Trojan without using any virus database. The Monitor utility constantly verifies the files you download, get via ICQ, or receive by e-mail\; the Executor checks any file before it is executed\; and the Scanner provides you with a virus search engine so that stealth, phantom, and worm viruses do not get away. The Cure module enables you to delete any discovered viruses, even if they are hiding behind Windows processes. PC Doors Guard does not intercept system resources, thus allowing you to use it with any other anti-virus application for maximum protection. Its comprehensive database includes data for over 1,100 Trojan horses.
