Effects[edit]
CoolWebSearch has numerous effects when it is successfully installed on a user's computer.[1] The program can change an infected computer's web browser homepage to coolwebsearch.com, and although originally thought to only work on Internet Explorer, recent variants affect Mozilla Firefox as well as others like Google Chrome. It can also create pop-up ads that redirect to other websites including pornography sites, collect private information about users and slow the speed of infected computers.
Coolwebsearch uses innovative techniques to evade detection and removal, and as such many common spyware removal programs fail to properly remove the software.[2]
Some versions of CoolWebSearch can be installed through drive-by installation, in which a computer browsing a webpage automatically installs CWS. CWS itself attempts to evade others by not labelling its ads, not providing an EULA, not providing any data about itself and not having a website. Certain variants insert links on random text, leading to advertiser websites. Other attempts to access websites are redirected to pay-per-click search engines that may install more malware display ads. Some variants of CWS also add links to pornography and gambling sites to the user's Desktop, Internet Explorer's bookmarks and history. Certain versions attempt to edit users' trusted sites and modify security settings as well as to hide from removal programs. Variants are often named for the effects they have such as msconfig, Msoffice, Mupdate, Msinfo and Svchost32.
Possible creators[edit]
The website claims that they are not responsible for the browser hijacking. They run an affiliate program that pays affiliates to direct others to their site with paid advertising links. Coolwebsearch.com's terms of service use the laws of Quebec, Canada, whilst their DNS registration lists an address in the British Virgin Islands, and their web server appears to be run by HyperCommunications in Massachusetts, USA. CoolWebSearch is also linked to CoolWebSearch.org and appears to be related to webcoolsearch.com. Investigation connected Stanislav Avdeyko, the Koobface hacker, with CoolWebSearch[3]
