Spyware Information: CWS.HomeSearchAssistent
This is a hijacker application. Hijackers take control of your web browser's settings, and usually change your homepage, search page or other default pages to point to web sites owned by the hijacker. Since the hijackers can make money just based on the number of visits to their web sites, they benefit from forcing you to view their web sites each time your web browser opens.
Method of infection: CWS.HomeSearchAssistent, also known as Home Search Assistent, may be the latest CoolWebSearch variant. It can be downloaded from removed url or it can be automatically installed via drive-by download.
CWS.HomeSearchAssistent appears to be closely related to CWS.about:blank. It is distributed on the removed url website, which claims to be run by "Petro-Line, Ltd". The domain name is registered to "Pavel Petroff (support-cc@yellow500.com)". Yellow500.com is a pornographic website. Therefore, the removed url website may be a facade for the distribution of CWS.HomeSearchAssistent.
Advertising: CWS.HomeSearchAssistent replaces Internet Explorer's home page with 'about:blank'. The 'about:blank' page, however is hijacked to display an advertising page. CWS.HomeSearchAssistent also creates popup advertisements.
Browser degradation: CWS.HomeSearchAssistent hijacks common Internet Explorer pages, including homepage, search page, blank page, and search assistant page.
Hijackers don't normally damage your computer or steal your personal information.
