Information about istsvc.exe file

"istsvc.exe" is part of ISTbar. This Internet Explorer add-in is spyware and a homepage and search page hijacker.
ISTbar may also install other parasites including TinyBar, ToolbarCrash, SearchbarCrash, RapidBlaster and Download Plus.
If you don't recall downloading ISTbar, it may have found it's way on your system by using an ActiveX control to silently install on your system by simply visiting a website. This is most common with adult content websites.
You should remove it.

If you can not remove istsvc.exe (because you can not locate it, or it is in use), download Anti-Spy.Info. This program can kill the process, delete or quarantine this file, or just list all security related information about this file and all other running background processes.
