Trojan Drev Downloader May Be a Trojan

Trojans install themselves secretly onto your computer, most often through your downloading a simple email attachment (often Trojans pose as harmless pictures). Most Trojans are able to gain complete control over your PC after installation. With this control, the Trojan and the hacker behind it may change your system settings, delete important files, steal your passwords, and watch your computer acitivity.

Infection Methods of Trojan Drev Downloader and Other Trojans

Most Trojans infect your computer by tricking you into launching an infected file. This poisoned file could disguised as a small file, such as a jpeg or other email attachment, or it might be downloaded via a website or FTP.

  • Email: Your PC may be infected with a Trojan when you download infected email attachments, or sometimes even when you simply open an email. Many Trojans exploit security holes in Microsoft Outlook. You may be able to reduce your chances of getting infected by a Trojan by using a spam-blocking software.
  • Websites: Your PC may be infected with a Trojan when you visit a rogue site. Many Trojans exploit security holes in Internet Explorer web browser so that by simply visiting a website you may unknowingly download a Trojan.
  • Open ports: If your computer runs programs that provide file-sharing functions – such as AOL Instant Messenger (AIM), MSN Messenger, and more – you may open your computer up to vulnerabilities. Using file sharing through these applications may create a network that gives attackers the opportunity to remotely access your computer.
