Questions about

Chumsearch – a browser hijacker which is closely related to other fake search engines, such as Trovigo and Trovi. This potentially unwanted program (PUP) has been actively used to hijack Mac operating systems with the help of MPlayerX, MessageViewer Toolbar, NicePlayer, SearchProtect, ValueApps, and similar freeware. Technically, it is not a virus. It is a potentially unwanted program which relies on bundling while trying to infiltrate target systems. Once it is done, attaches itself to Safari, Chrome, IE and other web browsers and starts redirecting its victim to third party websites.

The main purpose of Chumsearch is to generate revenue which is gained with the help of pay-per-click scheme. As soon as this PUP settles down, it starts collecting its victim’s search queries, sites visited, ads clicked and similar information which is typically related to his/hers search sessions. At the moment, Mac OS X is the most affected operating system but Windows users should be also aware about this threat. 

Additionally, after getting more knowledge about victim’s search sessions, it starts filling its search results with links leading its victim to sponsored content. The most important thing you should understand is that these links are hardly monitored by people who are hiding behind Chumsearch and there is no guarantee that you won’t find yourself redirected to a malicious domain.

Additional features applied by this search provider are also related to viruses that belong to browser hijacker category. According to the latest analysis, it might install various toolbars, extensions, and plugins behind your back. Additionally, by using this corrupted search engine, you won’t be able to find any relevant information because it includes sponsored links in its search results and prevents users from accessing Google, Bing or other reliable search providers. Apparently, you cannot trust this search engine; you should remove Chumsearch as soon as it appears on your screen.

To prevent redirects to sponsored, as well as malicious, websites, you need to stay away from ads and in-text links brought to you by this virus. You need only one click to find yourself on a site that was created for spreading malware.

If you see ANY suspicious offers to install additional software, opt them out without hesitation.
