HijackThis - Trend Micro USA

This looks like it could be of some help in getting your Windows OS back
to normal after Cleaning your Computer of a Virus Infection. I haven't
used this tool my self, since I don't do Windows any more;) But, I have
used the Trend Micro Online Scanner in the Past on my Windows OS's and
it was pretty good. Note on Online Scanners. If you should decide to use
one. Remember to Check all of the Scan Settings and make sure it Does
Not Delete any System Files Automatically, or else you may end up with a
Computer that will Not Boot!:O But, this Tool, HijackThis is Not a Virus
Scanner. It is a System Setting Scanner, that you can use to help you
get your System and Software ie IE Browser Settings and Such back to
"Normal"...
