What issues can a Trojan horse cause?

Trojans are a special kind of malware that is very popular among people with malicious intentions. The main reason for that is their ability to perform a huge variety of criminal tasks and malicious processes. Once inside the computer, a threat like Js_obfus.ymnjp Virus can execute some very harmful activities. For example, the hackers, who stand behind it, may use it to gain control over the infected computer. This way, they can secretly modify, delete, corrupt or replace all the software and data, found inside the system. As a result, the victims may lose control over their computer and may experience huge data loss. The hackers may use their remote access to force the infected machine to perform tasks such as spam and virus spreading or some other criminal activities, which serve their malicious intentions.

In many cases, serious system damage may be caused and the infected PC may become totally unusable after the Trojan’s attack. This malware may modify or delete vital system files, Registry keys or software components and cause the machine to become sluggish, experience frequent system errors or crashes. The victims will surely not be able to do anything on their computer because of these issues and a full reinstall may be the only solution for recovery. Another very harmful consequence of having a threat like Js_obfus.ymnjp Virus inside the system is the possible contamination with other tricky viruses such as Ransomware, Spyware, etc. Recently, a common practice of the hackers is to distribute Ransomware infections along with a Trojan horse. This way, if you get infected with Js_obfus.ymnjp Virus, you may also unknowingly catch a nasty cryptovirus of the ransomware type and become a victim of an online blackmail scheme. Such scenarios are very unpleasant, but they will only give you a general idea of what the tricky Trojans are capable of. That’s why, having the Js_obfus.ymnjp Virus infection removed as soon as possible is the best thing you could do, to prevent even worse virus contaminations and harmful consequences.

How can you catch a Trojan horse infection?

One of the favorite malware distribution methods of the hackers is the spam. Most of the infections they spread usually come in the form of a legitimate email or attachment, or some interesting offer or an ad. Sometimes, a compromised web page, a misleading link or an installer may also trick the users into clicking on it without having a clue that a Trojan horse infection could be lurking inside. That’s why a general safety rule is to use your common sense while browsing the web. Never interact with content you don’t trust and always stick to reputed software sources, known developers and sites.
