Search.tz-cmf.com – a browser hijacker that may alter web browser’s settings

A printscreen of Search.tz-cmf.com virus

Search.tz-cmf.com is another “masterpiece” of an infamous company known as Polarity Technologies Ltd. It has been classified as a potentially unwanted program (PUP)[1] due to the shady distribution method via software bundles. Besides, it belongs to a group of browser hijackers as it attacks most popular web browsers and injects its extension without requiring permission.

Search.tz-cmf.com virus can settle down on Google Chrome, Mozilla Firefox, Internet Explorer, Edge and any other web browser. Right after that, it initiates the following changes:

  • Corrupts default start page and search provider;
  • Replaces default new tab URL;
  • Installs unwanted browser’s toolbars;
  • Injects tracking cookies;

It won’t be easy to restore the changes mentioned above after the Search.tz-cmf.com hijack because the malware may install Browser Helper Objects (BHO)[2] to prevent detection and removal. Therefore, you may need to employ a reputable anti-malware, such as Reimage to get rid of it.

Search.tz-cmf.com removal is an essential step in maintaining your web browsing and privacy secure. According to Privacy Policy, this search engine uses tracking cookies to accumulate information, including, but not limiting to IP address, geographical location, the name of IS, browsing history, type of web browser, technical details about the software, search queries, and so on.

The developer of Search.tz-cmf.com virus can share gathered information with unknown third-parties that may further use it for sending you misleading advertisements.

Moreover, the Search.tz-cmf.com redirect virus can display altered search results. Although it generates Yahoo-based effects, some of the links may be predetermined. It means that clicking on them will redirect you to doubtful search domains. In the worst case scenario, you may be tricked into visiting phishing sites or installing malicious programs.

You can perform the removal manually with the help of manual removal tutorial provided below this article or run a full system scan with Reimage anti-malware.

Install freeware carefully as you might accidentally install suspicious extensions

The so-called browser hijackers and adware-type programs spread via free software bundles as optional components. However, the word “optional” is hardly suitable in this situation. Freeware developers usually hide third-party add-ons, toolbars, and extensions under Quick or Basic installation methods. They are marked by default, so people who opt for those installation methods intentionally agree to install all of them.

Researchers from lesvirus.fr[3] warn people to pay close attention to the freeware that you are about to install. Select them carefully and always follow these steps after the download:

  • To install the freeware, select Advanced or Custom installation method;
  • Read the entire License Agreement;
  • Unmark additional installers before clicking Finish button;
  • Finally, open Control Panel and check if no unknown programs have been recently installed.
