When all else fails, HijackThis v2.0.2
(
http://aumha.org/downloads/hijackthis.exe) is the preferred tool to use (in
conjuction with some other utilities). HijackThis will NOT fix anything on
its own, but it will help you to both identify and remove any
hijackware/spyware with assistance from an expert. **Post your log to

http://aumha.net/viewforum.php?f=30, or another appropriate forum for review
by an expert in such matters, not here.**
If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.
