Ads by WebOptimum

Also Known As: WebOptimum adware
Type: Adware
Damage level: Medium

What is WebOptimum?

WebOptimum is a deceptive application claiming to improve the Internet browsing experience. By offering valuable features, WebOptimum often tricks users into believing that it is a legitimate application.

Be aware, however, that WebOptimum generates intrusive online advertisements, causes unwanted browser redirects, and even infiltrates systems without users’ permission. For these reasons, WebOptimum is categorized as adware and a potentially unwanted program (PUP).

WebOptimum adware

The types of advertisements generated by WebOptimum include (but are not limited to) pop-up, banner, video, and audio ads. All are displayed using a 'virtual layer' (a tool allowing placement of third party graphical content on any websites visited), thus, none originate from users' visited websites.

By concealing the underlying content, third party advertisements significantly diminish the Internet browsing experience. Some redirect to untrusted sites that may contain malicious content. Clicking any advertisements generated by this adware is risky and might lead to further adware or malware infections.

Users' Internet browsing activity is continually monitored, since WebOptimum gathers various browsing-related information including IP addresses, website URLs visited, pages viewed, search queries entered into search engines, and other similar data that might contain personal details.

The developers of WebOptimum share this gathered information with third parties who are likely to misuse personal information to generate revenue. Therefore, the presence of WebOptimum can lead to serious privacy issues or even identity theft. We strongly recommend that you uninstall WebOptimum immediately.

WebOptimum is regular adware-type program and, thus, shares many similarities with other PUPs such as Dynamic Pricer, Internet Quick Access, and AmazingTab. These also claim to improve the Internet browsing experience, however, the purpose of adware-type applications is to generate income for the developers.

Rather than providing the functionality promised, WebOptimum, and other similar apps, generate intrusive online advertisements, and collect personally identifiable information. Users receive no real value.

How did WebOptimum install on my computer?

This program is often distributed as a 'bundle' with other software. Bundling is stealth installation of third party programs with regular software/apps. Many users are unaware that developers intentionally hide rogue apps within the 'Custom/Advanced' download or installation settings and, therefore, rush these processes.

By skipping most/all steps, they often install rogue apps inadvertently, expose their systems to risk of further infection, and compromise their privacy.

How to avoid installation of potentially unwanted applications?

This situation can be prevented by closely analyzing each step of the software download and installation processes. Closely analyze each step using the 'Custom' or 'Advanced' settings. Cancel all bundled programs, since there is a high probability that third party app will be bogus.

Download your chosen software from a trusted source only - freeware download and other similar software distribution sites often use download managers that bundle additional apps.
