  ISTbar Download sr.exe
ISTbar is an IE toolbar, homepage- and search-hijacker provided by Integrated Search Technologies/CDT Inc.

Installed by ActiveX drive-by download on affiliate sites, typically porn adverts, from April 2003. At least ISTbar/AUpdate is known to install using aggressive JavaScript (opening an error and re-trying if you refuse the ActiveX download).

Comments:

ISTbar/AUpdate installs a TinyBar variant to implement its toolbar, and will be detected by the script at this site as TinyBar/B. The hijacker is aimed at my-internet.info and blazefind.com; distribution is managed by searchbarcash.com, its controlling server.

ISTbar/XXXToolbar is an update based around porn. It uses its own toolbar code. The hijacker is aimed at its controlling server xxxtoolbar.com, and slotch.com; distribution is controlled by toolbarcash.com.

ISTbar alse installs other parasites: both variants install porn pop-up producer RapidBlaster/lp; the AUpdate variant is also known to install DownloadPlus.

Removal Instructions:

There is a entry in Add/Remove Programs for 'MS AUpdate' (AUpdate variant) or 'ISTbar' (ISTbar variant). Unfortunately this doesn't remove the toolbar in the AUpdate variant, or RapidBlaster in either variant.
