Un-stop Adware

What is un-stop?

Similar to VidSqaure, un-stop is a rogue application that supposedly allows users access to websites blocked in their own countries. Initially, this application may seem legitimate and useful, however, un-stop is classed as a potentially unwanted program (PUP) and adware.

There are three main reasons for these negative associations: 1) stealth installation without consent; 2) display of intrusive online advertisements, and; 3) tracking of users' Internet browsing activity.

Following infiltration, un-stop delivers coupon, banner, pop-up, and other similar advertisements. PUP developers often use a "virtual layer" to deliver intrusive ads. This enables placement of third party graphical content on any site. Therefore, the ads often conceal underlying content, significantly diminishing the browsing experience.

Furthermore, intrusive ads can lead to malicious websites or even activate scripts designed to download and install malware/PUPs. So, even accidental clicks can result in high-risk adware or malware infections.

As with most PUPs, un-stop monitors browsing activity by collecting various information such as IP addresses, website URLs visited, pages viewed, queries entered into search engines, and so on.

This collected data might contain personal details that PUP developers use to generate revenue by selling it to third parties (potentially, cyber criminals who also misuse the information for the same purpose).

Information-tracking apps such as un-stop pose a direct threat to your privacy and Internet browsing safety. Therefore, we strongly advise you to uninstall un-stop adware immediately.

un-stop shares many similarities with Quiclean, History Cleaner, Bizarrehall, and dozens of other adware-type applications. Most offer various "useful features", however, this is merely an attempt to trick users to install. In fact, adware-type applications deliver no significant value for regular users.

Their only purpose is to generate revenue for the developers. Rather than enabling the functionality promised, adware-type applications deliver intrusive advertisements (via the "Pay Per Click" advertising model) and collect various user-system information (which is later shared with third parties to generate revenue).

How did un-stop install on my computer?

un-stop has an official download website, however, cyber criminals also proliferate PUPs using the aforementioned intrusive ads, and by using a deceptive marketing method called "bundling" (stealth installation of third party programs with regular [mostly free] software/apps). Developers are aware that many users rush the download/installation procedures and skip steps.

They therefore hide bundled apps within the "Custom" or "Advanced" settings of these processes. Clicking dubious ads and rushing these stages often leads to inadvertent installation of PUPs such as un-stop and compromises users' privacy.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. Therefore, be cautious when downloading/installing software and browsing the Internet. Download your software from official sources only and (if possible) use a direct download link. As mentioned above, PUPs are distributed using the bundling method.

Therefore, using third party downloaders is very risky. If you are forced to use this method, carefully analyze each step (especially the "Custom/Advanced" settings) and cancel all additionally-included programs. Be aware, however, that in some cases bundled apps are concealed, thereby preventing users from opting-out.

We strongly advise you to avoid using these tools. Furthermore, avoid clicking any advertisements. Cyber criminals put a great deal of time and money into making rogue ads appear legitimate/genuine. No matter how tempting the ads seem, do risk clicking them. The key to computer safety is caution.
