The JSAgent.HTM Virus detected by Gateway Anti-Virus

Trojan-based infections are commonly considered to be very flexible and incredibly hard to identify and remove, thus, many web users fear them and don’t know how to effectively deal with a threat of this type. This piece of malware typically infects the computer in secret and launches various malicious processes there without the users’ knowledge or any apparent symptoms that can serve as red flags.

Gateway Anti-Virus Alert

Gateway Anti-Virus Alert will warn you if you are about to visit a site infected with JSAgent.HTM. JSAgent.HTM, in particular is a very problematic Trojan horse virus that has been disturbing a lot of people lately.

Most commonly, this malware can be used for espionage, theft of personal details, passwords and login credentials, banking and financial fraud, virus distribution and more. In general, a single Trojan can perform different types of harmful tasks one after the other. Once in the system, it can easily detect existing vulnerabilities and exploit them in a number of ways. For instance, a threat like JSAgent.HTM can act as a backdoor and sneak Ransomware, Spyware and other viruses inside the compromised computer. It can also provide hackers with remote access to everything that is stored in the system, including your data and your software. This Trojan can also allow them to control your web camera, your microphone and your screen and take secret records that can later be used for personal abuse, theft or blackmail.

Sadly, most antivirus programs are unable to accurately detect new Trojan-based infection such as JSAgent.HTM, Wup.exe, SAntivirusKD.sys if their virus and malware definitions have not been updated for some time or this malware has not been added to their database. The Trojan is practically invisible to the security program in this case and can easily attack the computer without being detected until its definitions are embedded in the database. Thus, an outdated antivirus program is basically useless since it may not alert the victims about the presence of the malware and its activities on the system which makes it even more challenging to recognize and remove Trojan threats in time. The more advanced the security software is and the more frequently its database is updated, however, the better the capacity to defend the computer from the newest cyber threats. That’s why the investment in reliable antivirus and antimalware software is a key factor for the effective protection of your system.

Unfortunately, if you rely on your observance to catch a threat like JSAgent.HTM you may not be able to detect anything because this malware typically does not show any visible red flags or symptoms of its presence in the system. If not removed on time, however, a single Trojan can be used for a range of criminal deeds which can cause unpredictable damage to the computer. That’s why, no matter what the end goal is, the virus should be eliminated as soon as possible, ideally with the help of the instructions in the removal guide that you will find below.
