What is CustomSearch?
CustomSearch is yet another potentially unwanted program (PUP) for Windows computers. This program belongs to the family of browser hijackers. Browser hijackers are designed to generate ad revenue. They change a web browser’s settings and/or homepage to inject unwanted ads into the user’s web browser. Browser hijackers can be used as gateways for other forms of malicious attacks. They may redirect users to malicious and scam websites. Browser hijackers can sneak into computers unnoticed due to the fact that it’s actively being promoted in freeware.
On installation, CustomSearch can silently modify various browser settings, such as the homepage and search settings. It changes homepage, new tab URL and search engine, redirects user searches to Bing (via customsear.ch or nseext.info):
CustomSearch in detail
Most often, PUPs and browser hijackers promote fake search engines by setting their address as the default search provider. In this case, the CustomSearch hijacker can install customsear.ch as a search provider. This means that users whose web-browser is affected with the hijacker are forced to visit the customsear.ch site each time they search in the Internet, open a new window or tab. And since customsear.ch is not a real search provider and does not have the ability to find the information users need, it redirects the user’s internet browser to Bing search engine.
VirusTotal flagged CustomSearch as malware:
CustomSearch can collect all kinds of information, including: IP addresses, web browser version and type, usernames and passwords, Internet Service Provider (ISP), internet cookies, webpages visited, auto-fill browser settings, and URLs visited. Such kind of behavior can lead to serious security problems or privacy info theft. This is another reason why the browser hijacker should be removed as quickly as possible.
Attackers often use browser hijackers to redirect users to fake dating sites, various diet pills scams, fake virus alerts that trick users to buy or install applications that are not needed, work-at-home schemes, fake surveys and giveaways, and other questionable content. Below are some examples of such sites:
