Web Timer Adware

Also Known As: Ads by Web Timer
Type: Adware
Damage level: Medium

What is Web Timer?

Web Timer is a deceptive application claiming to provide a number of browser-enhancing functions. These false claims often trick users into believing that Web Timer is a legitimate application, however, it is classed as a potentially unwanted program (PUP) and adware.

There are three main reasons for these negative associations: stealth installation without users' consent, tracking of web browsing activity, and display of intrusive online advertisements.

Web Timer adware

Following successful infiltration, Web Timer delivers pop-up, search, banner, coupon, interstitial, transitional, full-page, and other similar advertisements. To achieve this, developers (Yontoo) employ a 'virtual layer' - a tool that enables placement of third party graphical content on any site.

Therefore, displayed advertisements (that obviously do not originate from users' visited websites) often conceal underlying content. This significantly diminishes the web browsing experience. Furthermore, there is a high probability that the ads will redirect to malicious websites - clicking them can result in further high-risk computer infections.

Another downside of Web Timer is data tracking. This PUP continually records IP addresses, website URLs visited, pages viewed, search queries, unique identifier numbers, and other similar information. This data might seem insignificant, however, it might include personally identifiable details that the developers of Web Timer share with third parties.

These criminals can misuse private data, thereby causing serious privacy issues. You are strongly advised to uninstall this PUP immediately.

This application is very similar to hundreds of other potentially unwanted programs such as Search Expanse, Window Frame, Tide Search, and Search Adventure. As with Web Timer, these apps also supposedly offer 'valuable functions', however, claims to enhance the web browsing experience are merely attempts to trick users to install.

Adware is designed only to generate revenue only for the developers. Rather than providing any of the functions promised, apps such as Web Timer cause unwanted browser redirects, gather private data, and continually display intrusive online advertisements.

How did Web Timer install on my computer?

Web Timer is distributed using a deceptive software marketing method called 'bundling' - stealth installation of potentially unwanted programs with regular software. Developers are aware that many users do not express enough caution when downloading and installing software.

For this reason, they intentionally conceal all bogus programs within the 'Custom/Advanced' settings of the download/installation processes. By skipping this section, users expose their systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

This situation can be prevented by taking a number of simple steps. Firstly, closely analyze each step of the download/installation processes. Secondly, opt-out of all additionally-included programs and decline all offers to download/install them.
