Do You Have Anti-Virus and Trojan?

When you’re infected with badware — whether it’s Anti-Virus and Trojan, spyware, adware, a Trojan, or a virus — there are a few key symptoms. Have you noticed…

  • Slow computer performance: It just takes one parasite like Anti-Virus and Trojan to slow your computer dramatically. If your PC takes longer than usual to reboot, or if your Internet connection is unusually slow, you may be infected with Anti-Virus and Trojan.
  • New desktop shortcuts or switched homepage: Badware like Anti-Virus and Trojan may change your Internet settings to redirect your homepage to another site. Badware can even add desktop shortcuts to your PC.
  • Annoying popups: Badware can bombard your computer with popup ads, even when you’re not online. Through these popups, you may be tricked into downloading more spyware.

How Did You Get Anti-Virus and Trojan?

Wondering how Anti-Virus and Trojan ended up on your PC? If you’re infected with Anti-Virus and Trojan or other badware, perhaps you were using…

  • Freeware or shareware: Did you download and install shareware or freeware? These low-cost or free software applications may come bundled with spyware, adware, or programs like Anti-Virus and Trojan. Sometimes adware is attached to the free software to “pay” developers for the cost of creating the software, and more often spyware is secretly attached to free software to harm your computer and steal your personal and financial information.
  • Peer-to-peer software: Do you use a peer-to-peer (P2P) program or other application with a shared network? When you use these applications, you put your system at risk for unknowingly downloading an infected file, including applications like Anti-Virus and Trojan.
  • Questionable websites: Did you visit a website that’s of questionable nature? When you visit malicious sites that are fishy and phishy, badware may be automatically downloaded and installed onto your computer, sometimes including applications like Anti-Virus and Trojan. I recommend you use Firefox web browser, if you don’t already.

Understanding Anti-Virus and Trojan

If you’re infected with Anti-Virus and Trojan, you should know what you’re fighting. I’ll explain some definitions related to Anti-Virus and Trojan.

Anti-Virus and Trojan May Be Rogue Anti-Spyware

Rogue anti-spyware refers to anti-spyware/antivirus software of questionable value. Rogue anti-spyware may not be proven to protect your computer from spyware, may popup fake alerts or create many false positives about your PC being infected, or may use scare tactics to try to get you to purchase the application. Rogue anti-spyware software may be installed by a Trojan, come bundled with other software, or install itself through web browser security holes. While it is fairly rare, some rogue anti-spyware is created and distributed by known spyware or adware companies, and the rogue anti-spyware may install spyware or adware itself.

Often when you’re infected with rogue anti-spyware like Anti-Virus and Trojan, you’ll see a false popup security alert like this:

Rogue Anti-Spyware Tactics

Typically, rogue anti-spyware such as Anti-Virus and Trojan has one or more of the qualities listed below, which is why rogue anti-spyware is considered anti-spyware software of questionable value.

  • False positives/fake alerts: Rogue anti-spyware may produce a large number of false positives or use fake alerts, noting that your computer is infected with spyware parasites or other threats that do not really exist.
  • Copycat looks: Rogue anti-spyware may copy the look and feel of other legitimate or rogue anti-spyware applications. Often, rogue anti-spyware applications may appear as close clones of other rogue anti-spyware software.
  • High pressure marketing: Rogue anti-spyware may use scare tactics or other aggressive advertising and marketing tactics to try to trick you into buying the rogue anti-spyware application. Often, rogue anti-spyware may produce false positives and fake alerts about your computer being infected.
  • Poor detection/scan reporting: Rogue anti-spyware may produce poor reports when it scans your PC. For example, rogue anti-spyware may say your computer is infected 11 parasites, but not specify which spyware parasites or what type of parasites. Rogue anti-spyware may also report that your PC is infected with SafeAndClean, but not tell you which related files, DLLS, etc. were found on your computer.
  • Weak scanning/detection: Rogue anti-spyware may not only poorly report on computer infection, but rogue antispyware may also poorly scan your PC. Rogue anti-spyware may skip over important folders and files of your computer that should be scanned to detect spyware.

Did Anti-Virus and Trojan use these tactics to trick you into buying Anti-Virus and Trojan?

Anti-Virus and Trojan 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 Anti-Virus and Trojan 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.
