We just mentioned above that Trojans are the favorite tools of the cybercriminals and the reason for that is their ability to perform various harmful tasks. Practically, a virus such as Cobalt can be programmed for a wide range of malicious actions, some of which we already mentioned in the very first paragraph. This ability of the Trojans makes them very unpredictable and difficult to handle, since you never know what kind of harm you should expect. Another feature, which is helping this type of malware succeed in its criminal actions, is its stealthy methods of infection. Oftentimes, the victims are tricked in such a sophisticated way, that they are completely clueless about the ongoing infection and the presence of the malware for weeks or even months ahead. Usually, the hackers camouflage the danger as a harmless-looking file, an image, an interesting link or some email attachment. They spread it via social shares, torrents, spam email messages, software installers and various web pages. When the users come across the well-hidden Trojan, they often are not able to recognize it and carelessly click on it. A reputed antivirus program may be very helpful in this moment because, if regularly updated to the latest virus definitions, it may effectively recognize the danger. However, if the system has vulnerabilities and the protection is not reliable, any sophisticated virus such as Cobalt can easily get inside the computer. From then on, various harmful activities may be activated.

How can you remove Cobalt effectively?

Unfortunately, dealing with a Trojan horse can be challenging. Users, who are not familiar with malware removal are usually advised to use a professional removal tool (just like the one available below) or to contact a professional, who can remove the infection with all of its hidden scripts. Those of you, who want to try to remove Cobalt manually, may find the instructions in the Removal Guide below very helpful. They are detailed enough to guide you through the system, but still, it is very important how strictly you follow the steps and what kind of files you delete at the end. Make sure you correctly identify the Trojan-related files and not delete something else, which could be essential for the functionality of your operating system.
