antivirAntivir one of the hottest, most stressful new bugs in the rogue spyware world. Unfortunate victims are either tricked into downloading the virus or have it secretly installed unknowingly via a Trojan. Antivir is related to the popular, similarly disruptive spyware known as Personal Guard. You might think a scan is taking place, but it’s a fake.

  • Freeware or shareware: Many times freeware or shareware is secretly bundled with spyware. It is how the developers earn money for the time they spent. It’s a sneaky, but it’s fairly common.
  • 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 mistakenly downloading an infected file, including software like Antivir.
  • Questionable websites: Malicious or questionable websites can install programs such as Antivir through security holes and automatic downloads, such as video codecs. If you feel your browser is unsafe, consider using the newest version of Mozilla Firefox, Google Chrome, or Internet Explorer.

Automatic Removal. Bob Approved.

The risks of manual removal make automatic removal an easy decision for me. I don’t have enough time in the day to manually remove every infection that I come across; it’s way too time consuming, and risky. It’s easy to miss a file if you’re not careful, and it’s easy to adjust the wrong file and be left with a paperweight for a computer.
