Typically, this application settles down among the web browser’s plug-in list without being notices, since it is distributed in disguise with freeware[2] and shareware as an “optional” component. However, it can hardly be opted out because its installer is preselected and hidden under the Quick installation method.

The so-called Kerumal virus is not a malicious computer infection. Based on the website information online, the domain itself is not malicious. It’s a relatively new domain, i.e., one year and three-month-old, though it has been estimated that it attracts more than 9,000 visitors daily. However, one of the AV engines detect this URL as malicious, VirusTotal[3] reveals. Moreover, more than one forums related to cybersecurity claim that their web browser is continuously redirecting to the kerumal website and its affiliate domains. Finally, AVAST and MBAM are giving warnings saying:

Freeware distributors get monetized for each additional application installed, and there’s nothing wrong about that.

The latter was seldom checked for implementation of intrusive activities, such as a web browser’s hijack, ads, redirects, and similar. Currently, a significant improvement regarding freeware download websites is noticed, though people still have to be cautious when installing freeware since apps like Kerumal virus tend to pass malware checks.

Most of the Kerumal ads contain advertising material and may be linked to unpopular online markets. However, some of the pop-ups may report about bogus malware infection, offer to try a free virus scanner online, which eventually informs multiple malware infections and trick people into downloading scareware or another intrusive app.

Tips on how to avoid potentially unwanted programs

Potentially unwanted programs, such as adware or browser hijackers, do not feature malicious train in comparison to ransomware, spyware, or other highly dangerous infections. As they are not built on the grounds of malicious codes, they tend to bypass malware checks easily, which is why it is possible to run into adware or another potentially dangerous application on the official websites or even Google store. In this case, it is very helpful to make a brief analysis of the app by reading its reviews and comments on the Internet. Besides, download and install a reliable anti-malware software, which will inform you about hidden installers. 

However, reputable download websites are nothing in comparison to third-party download sites that contain typically paid programs for free. Such websites attract visitors due to a variety of legitimate and never-seen-before apps, although downloading them poses a high risk of malware intrusion or even virus attacks. In general, cybersecurity experts recommend people not to download freeware just for fun. Deliberately consider whether you need a new app and have a clear ground why you need it. Then initiate research on the selected application and, if it has a spotless reputation, download it from a reliable source[4]
