Exterminate It! Antimalware


Known threats:700,085 Last Update:August 24, 10:09


My browser was taking 10 to 15 seconds to load up instead of being instant. Three of the top anti spyware programs insisted all was well. However a few simple instructions from your team and the problem was magically solved.

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.

Be Aware of the Following Trojan Threats:

Bancos.HFD, Bancos.ICT, Agent.abu, Foxyt, Vxidl.ATP.


Worms are generally considered to be a subset of viruses, but have key differences. Unlike a virus, a worm is a computer program that replicates, but does not infect other files. Instead, a worm installs itself on a computer and then looks for a way to spread to other computers.

From a user’s perspective, there are noticeable differences. The longer a virus goes undetected, the more files it will infect on the victim computer. By contrast, there is just a single instance of the worm code on the computer.

Like viruses, worms are often subdivided according to the methods they use to infect a system. E-mail worms are distributed as attachments to e-mail messages. IM worms are attached to messages sent with instant messaging programs (such as IRC or ICQ). P2P (peer-to-peer) worms use file-sharing networks to spread. Network worms spread directly over the LAN (Local Area Network) or across the Internet, often exploiting a specific vulnerability.

Be Aware of the Following Worm Threats:

Backdoor.IRCBot, Agobot.bm, Satanik.Child.Installer, Win32.Kwbot, IRC.Fagot.

Hacker Tool

Hacker tools are utilities designed to help hackers gain control of remote computers in order to use them as zombies (in DoS attacks, for example), download other malicious programs into those computers, or use them for other malicious purposes.

Be Aware of the Following Hacker Tool Threats:

Notify, ProHack.Exe.Joiner, Win32.Evncil, CWS.Time, Autospy.

How Did My PC Get Infected with BAT.BWG?^

The following are the most likely reasons why your computer got infected with BAT.BWG:

  • 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 BAT.BWG. 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 BAT.BWG.

Visiting Questionable Web Sites
