Trojan horse viruses are well-known computer threats, which probably every computer user has heard of at least once. These threats are some of the most dangerous and hard-to-deal-with types of malware that one could encounter. On a global scale, the Trojans are responsible for almost 70% of all the computer infections. In today’s’ article, we are going to speak about one recently discovered representative, which the security experts have named AppHostRegistrationVerifier.exe. This Trojan is currently on the rise and the number of people infected by it is growing rapidly with every passing day. If you have fallen a victim to AppHostRegistrationVerifier.exe, stay with us to better understand the potential capabilities of this threat and the most effective ways to remove it from your computer.

Trojan horses – general characteristics:

Saying that the Trojans are extremely dangerous and problematic is not enough to describe their malicious capabilities. What makes these infections so threatening is the fact that they are usually able to infiltrate any computer and to operate inside of it without any visible symptoms. The infected users, unfortunately, may not have a clue about the presence of a Trojan such as AppHostRegistrationVerifier.exe on their machine until it causes some significant damage or carries out a malicious task that has some visible indications. And, trust us, the tasks that such a malware could perform could be really harmful in a variety of ways.

Some of the most typical ways in which you may get infected by a Trojan horse include you clicking on some contaminated content or on a well-disguised malware source. Now, the hackers who create threats like AppHostRegistrationVerifier.exe often rely on some very smart and tricky techniques in order to delude the web users and get them infected without their knowledge. Most of the time, the crooks disguise their malicious pieces of software as some form of a seemingly harmless type of content. Typically, the Trojan come under the guise of an executable file delivered through your email inbox, a spam message to any of your social network accounts, an ad, a link, a fake pop-up or an update notification that is supposed to trick the users into interacting with the compromised content. Naturally, the moment the victim clicks on the malware source, downloads the compromised file or installs the software that is used to spread the virus, the Trojan automatically gets inside the system and secretly starts carrying out its agenda.
