This page aims to help you remove Trojan.js.agent.tdd Virus. Our removal instructions work for every version of Windows.

Trojan.js.agent.tdd is a devastating piece of malware that was recently reported by a number of cyber security researchers. This nasty virus is a Trojan Horse and it can silently sneak inside any computer so long as user of the machine gets tricked into interacting in some way with a piece of content that carries the infection. The potential carriers of such threats can be many. The cyber criminals who use Trojans are highly creative in their methods of spreading their nefarious programs. Some popular techniques used for the distribution of infections similar to Trojan.js.agent.tdd are the use of pirated software, illegal sites, fake web ads, fake “you won a prize” banner or some other form of malvertising. Spam web messages are another very widespread and very commonly used technique for exposing more and more users to threats of the Trojan Horse category. In most cases, the malicious program would be put inside the spam e-mail as an attached file that the user is tricked into opening and/or downloading on their computer. Once the said file gets opened, the infection starts and the computer is no longer safe. However, as far as the potential symptoms are concerned, you may not notice anything if Trojan.js.agent.tdd or another similar Trojan attacks you. Some such infections tend to act more aggressively and may cause the computer to experience frequent freezes and BSOD crashes as well as random errors. This may sometimes draw the user’s attention to a potential Trojan Horse infection. There, however, are no guarantees that this would happen in your case. In most cases, if a Trojan is supposed to stay hidden and remain unnoticed for an extended period of time, it would most likely be able to do so. Still, since you are here, reading this article, you have probably noticed some odd and unusual activity in your system which is what brought you here. In this case, we advise you to follow the next steps to remove Trojan.js.agent.tdd in case it really has managed to infect your computer.
