The term ‘Trojan’ or ‘Trojan horse’ is familiar to pretty much ever online user these days.

If that weren’t the case, this wouldn’t have been the malware group responsible for nearly 80% of all malicious infections that happen. Thus, one of the latest Trojan horse variants better known as Addthis_widget.js has already managed to infiltrate quite the number of computers and yours is probably among them, since you’re made it to this page. It’s actually quite lucky that you have detected this Trojan, as one of their chief qualities is stealth. You’d be surprised, but a lot of the time Trojans that successfully make it inside their victim’s system can stay there for weeks and even months without being noticed.

What Trojans do and how to protect yourself from them in the future

Another key quality that Trojan horse viruses boast is versatility. They are capable of performing a staggeringly wide range of malicious actions, so we wouldn’t exactly be able to tell you what the mission of Addthis_widget.js on your PC currently is. But whatever it is – you can be sure that it’s no good. We have narrowed down the possible reasons it could have attacked your computer to some of the most popular usages of this malware type.

For example, Trojans are very commonly used to steal information from the computers they’re on. They can obtain it by a variety of means and then transmit it back to their evil masters. Say they are specifically after financial credentials, like online banking details, credit card numbers, etc. They can start logging your keystrokes so that everything you type into your keyboard is recorded by the virus and then sent over to the hackers behind it. Another method of stealing data, one that requires more resources, but can still be done – hijacking your traffic and forwarding it to criminal servers. As a result, not only what you type in, but absolutely everything you do online will be in the hands and in literally in front of the eyes of the cybercriminals behind Addthis_widget.js.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random

Other usages commonly involve exploiting your computer’s resources. This can be done for the purpose of mining cryptocurrencies, for example. As a result, your computer will be consuming a lot more power for seemingly no reason and the hackers will be benefiting from it without your knowledge. Alternatively, your computer can be used as a bot. In that case it could distribute malware, spam, etc. – also without your knowledge. A spin-chilling but also probable possibility is spying. The criminals behind Addthis_widget.js could easily be using it to keep tabs on you for whatever reason. And this includes watching you, listening to you, monitoring your activity and tracking your location.

Obviously, nobody would want to be subjected to any of those. And that’s not by far even the full list of horrible things that a Trojan like this could accomplish. Not to mention that it could even introduce other malware to your computer, such as ransomware. And the effects of that can often prove devastating. So once you have removed Addthis_widget.js from your system with the help of the below guide or the professional tool, which will do the job for you, it’s important that you provide adequate protection for your computer.

You can start by installing or upgrading your antivirus program. Be sure to also manually check for any OS updates and security patches that need to be installed, because an outdated system is always vulnerable to external threats. In addition, try to avoid all the most typical malware sources and methods of distribution. These most often include spam messages (emails, social media, messaging platforms) and infected online transmitters. For example, these could come in the form of fake system updated request or notifications telling you you’ve won a prize. Downloadable content available on different shady file-sharing websites can also very well be infected with Trojans or other viruses. So be sure to only use reliable download sources.
