And finally, a mention of Trojan-Downloader.Win32.CWS.j, another common site on malicious websites. This downloader is basically a small stub which downloads and installs variants of CWS, perhaps better known as CoolWebSearch. CoolWebSearch is a malicious program which was first reported circa 2003. Ever since, a huge number of variants have been found in the wild, most of them following the same pattern of hijacking the browser startup page and displaying pornographic pop-ups. Over time, CWS variants have become more and more complex and the latest versions include rootkit stealth components and retro features designed to terminate antivirus programs.
