CoolWebSearch
This is a very nasty and insidious spyware/malware program. Spyware experts are now saying that the makers are borrowing code from other malicious programs to install rootkit like features on infected machines.
More recent versions of CWS spyware now have features similar to rootkits which allow the program writers to hide their files on Windows operating systems.
These new variants can hide their settings in the registry and also hide rootkit files in alternate data streams.
The software is usually installed on a machine by visits to malicious websites or emails using various ploys to get users to download and install the script.
Once installed, CoolWebSearch will hijack browsers and redirect users to some of the several bookmarks it imports. When you attempt to change your homepage back again it constantly overwrites it, it slows down general performance and causes Windows to freeze, crash or reboot, and can also make you victin to a Denial of Service (DOS) attack.
