TrojanDropper:JS/Exjaysee.A is a detection named used by some security software vendors to describe a corrupted JavaScript file that may be used to download threats on the victim's machine. It is not uncommon for threat authors to use multi-stage methods to deploy threats to the computers of their victims. For example, the crypto-threats distribution may be executed with the help of macro-laced Office files that create a JavaScript which, once launched, connects to a remote Command & Control server to fetch the ransomware payload. In addition to this, these JavaScript files may be used to configure the threat on already infected computers, as well as to extract the contents of threats that have been deployed as archived files.

There are many ways that a file identified as TrojanDropper:JS/Exjaysee.A can get to your computer – downloading an infected e-mail attachment, downloading pirated software, or trying to download software cracks and key generators. Overall, pirated digital content is one of the most used ways to spread threats, and all computer users should stick to using legitimate software if they want to preserve their online safety.

If TrojanDropper:JS/Exjaysee.A has been detected on your computer, then there's no way to tell whether it has already managed to carry out its task or not. However, it goes without saying that the file linked to TrojanDropper:JS/Exjaysee.A should be deleted immediately, followed by a full system scan to ensure that the JavaScript-based Trojan-Dropper has not managed to deploy any threats on your computer.
