How to uninstall software force-opening the flashymass.com website?

Also Known As: flashymass.com pop-up
Damage level: Medium

What is flashymass[.]com?

Flashymass[.]com is a rogue website designed to load questionable content and/or redirect visitors to other untrustworthy or possibly malicious sites. There are thousands of such webpages on the Internet; chicheet.comndconsiderat.bizbestonclock.com, and nmuandwishto.biz are but a few examples.

Users rarely enter rogue sites intentionally. Most get redirected to them by intrusive advertisements or installed PUAs (Potentially Unwanted Applications). This software can infiltrate systems without explicit user consent. PUAs operate by force-opening webpages, running intrusive advert campaigns, and collecting browsing-related information.

flashymass[.]com pop-up redirects

Flashymass[.]com in detail

The behavior of rogue sites is determined by their visitors' IP addresses/ geolocations. This applies to flashymass[.]com as well; hence, whether visitors to it are presented with dubious material and/or get redirected elsewhere - depends on their IP addresses/ geolocations.

Additionally, these pages use deceptive tactics to lure visitors into enabling their browser notifications; likewise, flashymass[.]com is not an exception. This website employs fake CAPTCHA verification - "Click Allow if you are not a robot" - for this purpose. Should its notifications be allowed, flashymass[.]com will start running intrusive advertisement campaigns.

The delivered ads are more than just a minor annoyance; they are considered to be a danger to device/user safety. Upon being clicked, intrusive adverts redirect to various unreliable/malicious sites, and some can download/install software (e.g., PUAs) without user permission.

How do potentially unwanted applications operate?

Potentially unwanted applications can have varied functionalities, and these functions can be in different combinations. For example, these apps can cause redirects and/or deliver intrusive advert campaigns.

Furthermore, PUAs usually have data tracking abilities. They can record browsing activity (URLs visited, webpages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses/ geolocations, personally identifiable details, etc.). The gathered data is then shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted software on devices can result in system infections, severe privacy issues, financial losses, and identity theft. Therefore, all suspicious applications and browser extensions/plug-ins must be removed without delay - to ensure device integrity and user privacy.

Potentially unwanted applications in general

PUAs appear legitimate and innocuous. They also offer a wide variety of "useful" and "advantageous" functions. These features seldom work as advertised, and in most cases - they do not work at all.

The sole purpose of unwanted software is to generate revenue for the developers; hence, functionality and user safety are irrelevant. Instead of delivering on any promises, PUAs can force-open untrustworthy and malicious sites, run intrusive advertisement campaigns, and collect private information.

How did adware install on my computer?

PUAs are spread via downloaders/installers of other products. This deceptive marketing technique of packing regular programs with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, used pre-set options, etc.) increase the risk of unintentionally allowing bundled content into the system.

Intrusive advertisements are also used to proliferate PUAs. When clicked on, the ads can execute scripts to download/install these applications stealthily. PUAs may have "official" promotional/download webpages as well.

How to avoid installation of potentially unwanted applications?

It is highly recommended to research products before download/installation and/or purchase. Furthermore, only official and verified download channels must be used. Since untrustworthy download sources, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - commonly offer bundled and/or hazardous content.

Download and installation processes must be treated with care. Therefore, it is advised to read terms, explore all available options, use the "Custom/Advanced" settings, and decline download/installing supplementary apps, tools, features, and other additions.

It is just as important to exercise caution when browsing. Intrusive adverts appear ordinary and harmless; however, they redirect to unreliable and questionable sites (e.g., gambling, adult-dating, pornography, etc.). In case of encounters with ads and/or redirects of this kind, the system must be checked and all dubious applications and browser extensions/plug-ins detected - immediately removed from it.

If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
