Web Optimum might bombard your web browser with annoying ads

The picture of ads by WebOptimum

WebOptimum is an adware[1] program that is responsible for delivering tons of advertisements on the affected web browser and redirecting users to the promotional websites. This potentially unwanted program (PUP) usually sneaks inside the system bundled with various free applications.

The WebOptimum virus has been noticed spreading in the form of the browser extension. This add-on is not available in the official app stores, such as Chrome Web Store. However, it might arrive on the system in the software bundle. One of the first signs of the browser hijack is changed homepage to EZ Search.

If adware sneaks inside the system you can find one of these processes running too:

  • WebOptimum.exe,
  • WebOptimum-bg.exe,
  • WebOptimum-bho64.dll,
  • WebOptimum-nova.exe.

If you see one of these processes running on your PC, you should scan the system with ReimageIntego or another anti-malware to remove WebOptimum from the device until it hasn’t flooded your browser’s with ads. This adware might cause havoc when you browse the web using Chrome, Firefox, Internet Explorer, Safari, and other web browsers.

The Web Optimum adware might compromise DNS settings[2] and enables its extension by force. Right after that, seeking to generate advertising revenue boost traffic to affiliate websites, it starts generating targeting advertisements. “Web Optimum Ads” are indeed intrusive. They show up on random websites and in very irritating forms (pop-up ads, banner ads, in-text links, interstitials, video ads, new tab ads, etc.) and can be excluded into two main categories:

  • Sponsored advertisements. Web Optimum redirects typically make people visit affiliate websites that need to increase page rank or boost sales. Such advertisements are annoying because due to their intrusiveness you may click on them accidentally and be redirected to unwanted websites quite frequently. Security experts from Les Virus[3] note, that ad-supported program might redirect to potentially dangerous websites too.
  • Fake advertisements. In some of the occasions, Web Optimum virus may generate third-party ads that may be used for spreading malware/PUP or even virus.[4] Such pop-ups may or may not be marked as “Ads by WebOptimum.” Anyway, such ads typically urge people to upgrade Java, Media Player, Flash Player, VLC Player, web browser, download manager, and so on. Thus, clicking on “Download” or “Update now” buttons can lead to other computer-related issues.

Potentially dangerous WebOptimum redirect tendencies are not the only problem related to this cyber threat. This PUP might also use tracking cookies to collect various information about users, including search queries, pages viewed, data that attract people's attention, and collection of PC's IP address, approximate geolocation, email address, and similar non-personal information.

However, no one can assure that adware cannot collect and share with third-parties personal details as well. Thus, in order to avoid privacy-related issues,[5] you should focus on WebOptimum removal as soon as you found suspicious ads on your browser.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
