A Trojan horse virus is a common computer threat infecting computers and spreading throughout the internet even now. The Trojan horse virus is categorized depending on how they breach and damage computers. The seven main types of Trojan horse virus are:

A Trojan horse virus can infect computers in a variety of ways cleverly hiding inside many seemingly useful software, programs and other executables. A computer can be infected with a Trojan horse virus through e-mail attachments, portable devices like memory cards and mp3players, instants messengers such as Yahoo messenger, Skype, MSN, and downloading movies and music from file-sharing sites. The Trojan horse virus can even disguise itself as an anti-virus program, thereby introducing viruses to your system instead of protecting it.
A Trojan horse virus is capable of stealing information from an unsuspecting user–stealing and sending passwords, credit card numbers, and address book entries. And through remote access, the designers of the virus will then have a level of control over the infected computer.
A computer system infected with this virus will experience significant lagging, slow boot-up, unexpected windows popping up even with the computer on stand by, loss of files, crashing of hard drive, and finally, system failure.
The best way of preventing your computer system from getting infected with a Trojan horse and other viruses is to regularly update your anti-virus program, or through the use of Trojan horse remover tool, if your system is already infected with the virus. The Trojan horse remover tool and antivirus programs are designed to detect and delete the Trojan horse virus infection and also prevent them from entering and being installed in your computer system. But the Trojan remover tool and even the best anti virus programs cannot guarantee your PC from ever getting infected with Trojan horse and harmful viruses. Prevention is the key. Avoid downloading attachments and file in e-mails that have been sent by unknown senders.
