What is Anti-Trojan?

Anti-Trojan 5.5 is a powerful trojan scanner and remover which detects more than 10000 different types of trojan horses. It uses three methods to find them. The first is the portscan which gives you information if there are open ports on your computer. The second one is the registry scan which searches through the system registry database for trojans. The third and the most important part is the disk scan. It scans your harddisks for dangerous trojan files and removes them safely.

Anti-Trojan Features:

• Port-Scan
  Here all port of the computer are checked whether a trojan is active. This port scanner checks in contrast to the online check all ports, not only well-known trojan ports. Note: There will be no trojan removed, only open ports are shown.
• Registry-Scan
  With this procedure the system is submitted to a high-speed check. There will be checked the system-registry an known filenames of trojans. If a trojan is identified, it will be removed.
• Disk-Scan
  This is the most important search method. Whole drives (or directories) are searched for trojan files. Each file is checked on the harddisk. With larger harddisks this search can last somewhat longer. As appoximate value we checked 20 GigaBytes in approx. 30 minutes (approx. 170,000 files). Anti-Trojan also checks packed archives of the following formats: ACE, ARC, ARK, ARJ, CAB, DWC, PAK, ?Q?, GZ, LBR, LHA, LZH, RAR, SFX, TAR, TAZ, TGZ, Z, ZIP, ZOO.

Free online updates are available. The background-guard watches for active trojans while you are working on your PC.
