    In how many ways can JS/Flafisi.D infiltrate your system?

    Typically, Trojans like JS/Flafisi.D can infect you without any actual symptoms. This malware spreads itself in a number of ways, but the security experts typically highlight five main ways that such a Trojan can eventually get into your system:

    • A great number of infections happen through malicious email attachments and spam messages, which carry contaminated data. The Trojan typically relies on camouflage to mislead the victims about its real nature and purpose and is often presented as a useful plugin, an application, a link, an offer, a software installer, or even an amusing image, audio or video file. Once it tricks the users into opening it, the infection silently installs its scripts on the system and tries to hide its traces.
    • A threat like JS/Flafisi.D may get inside the system via a weaknesses in your browser or security holes in your system. Outdated software and skipped installation of security patches may easily be exploited by such malware.
    • The hackers often insert their malicious payload inside insecure sites, which are filled with harmful links or which distribute unreliable pop-up ads. If a visitor lands on a similar site and clicks on the generated advertising content, the computer might get automatically infected. Sadly, nothing suspicious can be noticed at the moment of the infection because the threat does not show any unusual symptoms or warnings.
    • Trojans may be integrated into software installation packages. They may even resemble legitimate programs and prompt you to install updates or new, free, or test versions of popular software, which are, in fact, fake and used to deliver the malware to your system. You can also download this threat as a torrent, spam message attachment or a popup offering a Java or Flash Player update.
    • Different shareware, freeware and torrent platforms may also be used as distributors for Trojans. That’s why, you should be careful with the sources you use to download software and stick to reputed web locations.

    As you can see, a Trojan like JS/Flafisi.D can sneak into the system from various Internet sources such as insecure web pages or networks. The best way to save yourself from its malicious actions is to remove it as soon as possible and ensure that your PC has no security vulnerabilities and is protected with a reliable antivirus tool.
