The characteristics of a Trojan Horse – infection and symptoms

As we said above, stealth is one of the main reasons why viruses like Background.js are so successful and so popular among all kinds of hackers and online criminals. Typically, a Trojan would come to you as something that doesn’t initially look threatening since those virus programs usually use different forms of disguise and rely on the user’s negligence and lack of care. Anything from illegally distributed programs, games and other software to deceitful online ads, offers and update requests could be a potential carrier of Trojan Horses. Also, we shouldn’t forget about the various forms of spam messages that could also carry such infections. A Trojan like Background.js could easily get sent to your e-mail or to any of your social network accounts in the form of a seemingly harmful message attachment. The important thing here is to never interact with any type of content that you come across on the Internet if you can’t be certain that it isn’t something potentially harmful.

One other issue with Background.js and other Trojans is their overall lack of symptoms and red flags which is why it’s advisable that you always keep a trusty and fully-updated antivirus program on your PC. Also, though not always, a Trojan could still cause different types of system disturbances such as errors, crashes and excessive RAM and processor use so always be on the lookout for such irregularities as they might indeed indicate that there’s malware on your computer.

Potential uses of Background.js and other Trojans

There are many different ways a Trojan virus could be utilized. As we mentioned, those versatile threats could spy on you, steal data from your computer, gain access to your online accounts, take control over your PC, fill the computer with more malware (Ransomware, Rootkits, etc.) and many others. It is thus oftentimes difficult to predict what the type of damage would be and what the malicious program would be used for in each separate case. However, one thing is always the same and that is the importance for taking swift action towards cleaning your PC and removing all Background.js-related data. Otherwise, if the malicious Background.js is allowed to remain on your computer, there could be all kinds of negative consequences that you’d surely not want to have to experience.
