A trojan is a program that is disguised as legitimate software but is designed to carry out some harmful actions on the infected computer.

Unlike viruses and worms, trojans don’t replicate but they can be just as destructive.

These days trojans are very common. Trojans are divided into a number different categories based on their function or type of damage.


Of all trojans, backdoor trojans pose the greatest danger to users’ PCs because they give their authors remote control over infected computers. They are downloaded, installed, and run silently, without the user’s consent or knowledge. Upon installation, backdoor trojans can be instructed to send, receive, execute and delete files, gather and transfer confidential data from the computer, log all activity on the computer, and perform other harmful activities.

How Did My PC Get Infected with BO2K?^

The following are the most likely reasons why your computer got infected with BO2K:

  • Your operating system and Web browser's security settings are too lax.
  • You are not following safe Internet surfing and PC practices.

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like BO2K. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.

Using Peer-to-Peer Software

The use of peer-to-peer (P2P) programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like BO2K.

Visiting Questionable Web Sites

When you visit sites with dubious or objectionable content, trojans-including BO2K, spyware and adware, may well be automatically downloaded and installed onto your computer.

Detecting BO2K^

The following symptoms signal that your computer is very likely to be infected with BO2K:

PC is working very slowly

BO2K can seriously slow down your computer. If your PC takes a lot longer than normal to restart or your Internet connection is extremely slow, your computer may well be infected with BO2K.

New desktop shortcuts have appeared or the home page has changed

BO2K can tamper with your Internet settings or redirect your default home page to unwanted web sites. BO2K may even add new shortcuts to your PC desktop.

Annoying popups keep appearing on your PC

BO2K may swamp your computer with pestering popup ads, even when you're not connected to the Internet, while secretly tracking your browsing habits and gathering your personal information.

E-mails that you didn't write are being sent from your mailbox

BO2K may gain complete control of your mailbox to generate and send e-mail with virus attachments, e-mail hoaxes, spam and other types of unsolicited e-mail to other people.
