HiJack This is an extremely useful and powerful tool, and generally has been reserved for power users only. We are hesitant to list it here, as you can easily destroy your software installation if you don't know what you're doing. However, it is great for generating a log file which a power user can help you read to determine what may be going on with your system.
*** WARNING *** DO NOT USE THIS APPLICATION WITHOUT READING THIS ENTIRE PAGE
Do NOT have hijack this fix ANY problems it may find in the logs it produces. The logs list many things, most of the time they are fine and do not cause any problems and are actually required for your machine to continue to function.

How it Works
HiJack this is basically a deep scanner which can tell you exactly what is running on your computer. It can show things that might not show up in traditional scans. What you want to do is generate a logfile for examination by someone who knows how to read it. (This could be you.)
When to Use HijackThis
