Qtpcap is a stealthy Trojan horse infection aimed at exploiting system vulnerabilities and launching harmful activities in the background of the system. Users infected with Qtpcap may experience system corruption, theft of personal data, espionage and many other criminal activities.




Qtpcap is a new Trojan horse representative that is currently distributed on the Internet with the help of many malicious transmitters. It is very likely to land this virus on your computer if you are not careful where you click online. Emails with malicious attachments, spam messages, malvertisements, and harmful pop-up links, could often be used to secretly spread Qtpcap all over the web. Low-quality web sites, cracked apps, torrents, and illegal platforms can also be places where such a Trojan infection can lurk and wait for its victims. The actual contamination usually involves interaction from the user’s side, such as actually clicking on an infected link, opening a harmful message or downloading a file or a fake update. Regrettably, during the moment of infection and after the malware is downloaded in the system, no signs can be detected of its presence. Having  reliable security software, in most cases, is the only way to search the whole operating system for hidden malicious code and catch the Trojan horse on time.

Most people infected with Trojans such as Qtpcap can become victims of data theft, system hacking, unauthorized system and software changes, irreparable OS damage, removal or modification of important files and similar harmful effects. The offenders who stand behind the Trojan infection can program it to perform different criminal activities. For instance, they can set it to locate and exploit system vulnerabilities so that Ransomware, Spyware or other malware can later on be snuck into the system.

The worst aspect of infections of this type is that the victims, in many cases, do not know that they have been contaminated and that a harmful activity is running in the background of their system. The absence of symptoms helps threats like Qtpcap remain hidden and perform their criminal agenda without interruption.

Security experts advise that if you have even a slight suspicion that a Trojan has sneaked inside your computer, you should immediately scan the system with professional malware removal software and remove anything that gets detected as harmful or potentially unwanted. The reason is, if not detected on time, a single Trojan Horse can severely damage the entire computer, steal important information, destroy valuable data and even invite other viruses inside the computer. That is why we described manual steps for finding and removing the infection in the removal guide below.

Completing the manual steps, however, may require some computer literacy and can hide a risk for your system’s safety if not repeated correctly. This is why we suggest that users who do not rely on their computer skills should not experiment to remove Qtpcap manually, but use a professional removal tool of their choosing. If you don’t have such a tool at hand, there is a trusted program that can help you deal with Qtpcap which is available in the removal guide that follows.
