What is fiber.js and why does it continuously appear on my screen?

Fiber.js name in Windows Script Host warning may start appearing on your computer’s screen periodically. However, you should never ignore it because the appearance of this Windows Script Host alert and fiber.js name in its text should notify you that your computer is infected with some kind of a malware, for example, adware, a browser hijacker or other virus. So, no matter that this error message is really annoying, it’s actually a good thing because it warns you that you need to scan your system with a reliable anti-spyware and find potentially unwanted programs (PUP) that are hiding in it. For that, we recommend using ReimageIntego or any other reputable anti-malware.

Usually, the fiber.js adware/hijacker start their work right after infiltrating the system. They modify its settings and then start causing various advertisements that try to redirect people to questionable websites. The aim of such adwares, browser hijackers and similar PUPs is to promote third-party content and, mostly, boost the web traffic of their websites. This way adware programs generate pay-per-click revenue for their developers but there is no guarantee that you won’t be redirected to a malicious website. If you think that Fiber.js virus or similar potentially unwanted program has already entered your computer without an authorization, it is needless to say that you need to think about immediate their removal.

How could Fiber.js virus enter my system?

You should know that potentially unwanted applications generally slither into your computer seamlessly – and it is often done with a help of bundling. It means that if you have recently downloaded a freeware program, you probably have received a software pack which included something more than just your desired program, because the developers of PUPs tend to not disclose the fact that additional apps will be installed. If you want to ensure that you will install only the preferred program, you can check this on the installation settings page. Expand the window by clicking “custom” or “advanced” mode and you will see a list of agreements to install additional add-ons, plugins, extensions and similar componets ware, browser hijackers, plug-ins or add-ons. To reject such additional material, simply untick all the boxes near these lines.

Also, our researchers found out that people are discussing this error message on web forums – and it seems that commonly people receive this pop-up error message if a Dregol.com browser hijacker has invaded their systems. So it seems that Dregol.com may be one of the main PUP’s that contain the fiber.js file. Dregol.com is an untrustworthy search engine that is not recommended using because it injects advertisements between the search results. As any other malware program, mostly it enters PC user’s system without user’s consent.

Is there a way to get rid of this annoying fiber.js pop-up message?

As we have already mentioned, fiber.js virus can be deleted by uninstalling this PUP that is running in your PC system. For example, we have found that one user has shared his experience of getting rid of this program: “I turned my attention to scheduled tasks and found two suspiciously looking ones: “Run_dregol” and “Dregol cide”. It looks like “Dregol” is adware. […] I deleted all these files and have not seen this pop-up ever since.” To sum up, the appearance of fiber.js is an alert that you need to look through your PC and delete any adware or browser hijacker that hides in your system.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
