FF Helper Checker Firefox add-on causes unwanted activities on the affected browser

Screenshot of FF Helper Checker adware

FF Helper Checker is a potentially unwanted program (PUP) that targets Mozilla Firefox users. This add-on is harshly promoted on compromised websites and after infiltration might flood the browser with commercial content, such ads, pop-ups, etc.

Netizens are often redirected to such website after visiting a potentially dangerous site, for instance, gambling or adult-themed. However, scammers also take advantage of adware programs to spread FF Helper Checker virus too. For this reason, users might be forced to visit such site after incorrect freeware[1] installation.

The FF Helper Checker website has a malicious JavaScript that displays a fake warning about the necessity to update Firefox manually. The website states that this update is needed to protect users activities online and decrease possibility to encounter virus or malware attacks,

Additionally, the compromised delivers a pop-up that asks to install an FF Helper Checker add-on. Users are warned not to click “Cancel” button which is supposed to reject installation of the unwanted app and help to leave the website. However, scammers use obfuscated buttons which performs opposite tasks.

If you click “Cancel” on the FF Helper Checker pop-up, you will turn Mozilla Firefox into full-screen mode. It means that you might not have any other choice, just to install it. However, if you found yourself in such compromising situation, you should force quit the browser.

If you think that the add-on may still be installed on the system, we highly recommend scanning the device with reputable anti-malware software. If your machine was actually infected, a tool like Reimage Reimage Cleaner Intego would remove FF Helper Checker and other malicious components within a couple of minutes.

However, the malicious extension is known for being capable of blocking about:addons page. It means that FF Helper Checker removal might be impossible unless you run Firefox in Safe Mode.[2] You can find detailed removal guide at the end of this article.

Software installers might hide potentially unwanted applications

When you download free programs from the internet, you always have to choose between Advanced and Recommended installation settings. Researchers from semvirus.pt[3] tell the majority of users rely on the latter options.

The issue with Recommended installers is that they do not openly disclose about additional applications that might be attached to the primary program. Hence, by using this setup, you give indirect permission to install everything that was added to the bundle.

Now you can understand how FF Helper Checker hijack may have occurred – during one of the recent freeware installations. However, this could have been avoided if you have opted for Advanced setup and unmarked pre-selected additional downloads.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
