Blank Trojan Horses are programs that can spread to your computer, and damage your computer and information. These programs can infect the Internet by slowing it down. Blank Trojan Horses can be disguised in the form of an email. These emails include attachments that are harmful to your computer. A free downloaded software from a website you don't trust can also contain viruses. The following contains more information about Blank Trojan Horses.

Examples of Blank Trojan Horses

An example of a Blank Trojan Horse is OSX.RSPlug.A Trojan Horse. This Trojan horse is not a virus. It can't spread from one computer to the other. This malware can infect your computer if you click on a video where a message appears saying that your computer doesn't have the necessary codec. It can start downloading to your computer and asks for your administrator's password.

The domain name system (DNS) on your computer changes to point to a malicious DNS machine. This means that when you began to surf the internet, it can take you to a phishing clone of the site you typed in your browser area. It usually directs you to a porn site. You can be directed to any other site on the web.

VBS.Blank.A is another example of a Blank Trojan Horse. VBS.Blank.A is a script that changes your home page to \Windows/AboutBlank.htm, which is connected to your home page. If this site shows up on your computer, this means your computer contains malware.
