Thank you for the note. I have been a TrendMicro client for the last few years and was impressed with the speed of Exterminate It’s scan. I appreciate the efforts to help rid my system of Vundo, the commitment to stand behind your guarantee (unfortunately that is a rarity these days) and the customer service you have offered. I wish you and the company the best.

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.HNU, Pigeon.AOV, WordMacro.Talon, Bancos.HOG, Pigeon.AOZ.


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.

Be Aware of the Following Backdoor Threats:

Win32.NetSpy, Sheldor, Prosti, FTPPW, Backdoor.Cafeini!Server.

How Did My PC Get Infected with Zasil?^

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

  • 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 Zasil. 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 Zasil.

Visiting Questionable Web Sites

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

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

Zasil 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.
