Remove Fiber.Js


How Harmful Is Fiber.Js

This is a virus based primarily on advertisement activities. Its removal is more than recommended, unless you are prepared to absorb some severe losses in terms of the time it would take to restore your system to its previous level. Adware are not the most threatening viruses out there, but rather the backdoor other viruses use to slither in. With this in mind, please feel free to skip to the removal section below, but take your time to read the rest later. I’m hoping it can be quite useful to you, since I’ve designed the article to include sections that should be helpful in avoiding malware in the future.


This virus is usually accompanied by the picture you see above and the following message:

  • Windows Script Host
    Can not find script file C:ProgramData335CDB9F-63DE-0A19-D258-7A9B02DAA9151.9.1.1fiber.js.

If you’ve seen this, then undoubtedly you’ve come to the right place, as this virus can lead to pretty significant system errors over time. The first very important note you should make is to NOT update or install anything that your PC wants. It is the virus 90% of the time. It is disguised as a real program, because the majority of users fall for that trick. This is the key here – adware do not have access to anything unless you let them, hence they do everything in their power to manipulate them into giving them clearance. If you just ignore every message saying there’s a missing plugin, install XXX player to continue, Java or FlashPlayer needs an update, a newer version of whatever is out – then you should be perfectly fine. Do not let yourself be deceived. Typically the damage that Fiber.Js manages to inflict is collateral, in the sense that it just invites other viruses and they are the real threat. But they are a near immeasurable problem. We’ve found out that some malware start exposing your personal information and passwords to the people who created it. Suddenly all your accounts may change allegiances, even your bank accounts.

How Fiber.Js Works

Fiber.Js itself works through a bombardment of advertisements. As well as being immensely annoying, a bad side effect of all the hyperlinks is a slowing down of your CPU, which leads to system errors, browser crashing, and frequent stuttering. You should be glad to know that all of these will be in the past once you’ve removed the virus. The banners and ads themselves are very selective apparently, even if at the beginning they seem useful for giving you competitive prices on products you’re interested in. In essence, all they exist for is to lure you to the websites. That is done for two main reasons:

  • Either to promote said websites, because the virus owners own them as well.
  • Or the creators were hired and they make money from good old pay per click.

How Fiber.Js Entered My Computer

Well, basically it marched through your front door. One easy way to contract the virus is by opening spam email. This may sound surprising, because it’s a very obvious method, but it works nonetheless. Typically users are confused when they see a legitimate institution contacting them, the FBI or something related to tax. It may even be a a firm that supposedly sends the wrong address details for a deal. These are all fakes that can be discerned by spelling errors and bad grammar. At any rate if you click links in the email or download attachments, you get a nasty virus.

The second and more prominent way is by getting installed with another software. Free software are well-known for having viruses in their setups. It has to ask you at some point if you wantto include the “bonus” which of course you don’t want, because you’ll end up with Fiber.Js. Keep your eyes peeled from now on if this is what happened. Never include side material a program proposes.
