Updated on April 04, 2026
Any malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of morality – they utilize all possible methods. Stealing your personal data, getting the payments for the promotions you watch for them, exploiting your CPU and GPU to mine cryptocurrencies – that is not the full list of what they do. Do you like to be a riding equine? That is a rhetorical question.
What does the pop-up with Trojan:JS/FakeUpdate.B detection mean?
The Trojan:JS/FakeUpdate.B detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware software is pretty good at scanning, but prone to be mainly unreliable. It is defenseless to malware attacks, it has a glitchy interface and bugged malware removal features. Hence, the pop-up which says concerning the FakeUpdate is simply an alert that Defender has actually identified it. To remove it, you will likely need to make use of a separate anti-malware program.
Microsoft Defender: “Trojan:JS/FakeUpdate.B”
The exact Trojan:JS/FakeUpdate.B virus is a very undesirable thing. It sits inside of your computer disguised as a part of something legit, or as a part of the program you downloaded at a forum. Therefore, it makes everything to make your system weaker. At the end of this “party”, it injects other viruses – ones which are choosen by crooks who control this virus. Hence, it is impossible to predict the effects from FakeUpdate actions. And the unpredictability is one of the most upleasant things when it comes to malware. That’s why it is rather not to choose at all, and don’t let the malware to complete its task.

Is Trojan:JS/FakeUpdate.B dangerous?
As I have specified previously, non-harmful malware does not exist. And Trojan:JS/FakeUpdate.B is not an exclusion. This virus changes the system configurations, modifies the Group Policies and Windows registry. All of these components are crucial for correct system functioning, even when we are not talking about Windows security. Therefore, the malware which FakeUpdate carries, or which it will download later, will try to get maximum revenue from you. Crooks can grab your data, and then push it on the Darknet. Using adware and browser hijacker functionality, embedded in Trojan:JS/FakeUpdate.B malware, they can make revenue by showing you the advertisements. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.
How did I get this virus?
It is hard to line the origins of malware on your computer. Nowadays, things are mixed, and spreading ways chosen by adware 5 years ago can be used by spyware these days. However, if we abstract from the exact spreading tactic and will think about why it has success, the reply will be quite uncomplicated – low level of cybersecurity knowledge. People click on promotions on weird sites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” believing that the odd banner that states about malware is true. It is essential to recognize what is legit – to stay away from misconceptions when attempting to find out a virus.

Nowadays, there are two of the most extensive methods of malware spreading – lure e-mails and injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to understand a fake – the 2nd one is easy to get rid of: just do not utilize cracked applications. Torrent-trackers and various other sources of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:JS/FakeUpdate.B is just amongst them.
How to remove the Trojan:JS/FakeUpdate.B from my PC?
