When you’re infected with badware — whether it’s MyCentria, 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 MyCentria 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 MyCentria.
  • New desktop shortcuts or switched homepage: Badware like MyCentria 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 MyCentria?

Wondering how MyCentria ended up on your PC? If you’re infected with MyCentria 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 MyCentria. 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 MyCentria.
  • 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 MyCentria. I recommend you use Firefox web browser, if you don’t already.

Understanding MyCentria

If you’re infected with MyCentria, you should know what you’re fighting. I’ll explain some definitions related to MyCentria.

MyCentria May Be Adware

Adware is software designed to promote advertisements. Often, free utilities may install hidden adware, sometimes to earn money for the author to recover development costs. While adware is not always malicious, it can track your Internet activity and send this and other personal information from your computer to advertisers. When advertisers get this information, you may be a target for pop-up/pop-under advertisements, web browser toolbars, and spam.
