Hi,

You seem quite unprotected so you must get a firewall and antivirus, and keep them up to date.

Try "Browser Hijack Blaster"...........................It could fix your problem.

Sometimes this crap gets into the Windows Hosts file:

Try "Host Administrator"

Certainly go for http://www.diamondcs.com.au

Get "Registry Prot"................................It helps if you don't let them in in the first place

And: http://www.spywareinfo.com/~merijn/index.html Get the "Hijack This" application.

Do get "Win Patrol" from BillP Studios, as already suggested. Check out all its features, it does a lot more than protect the browser settings.

Just a few ideas..........hope they help

Cheers
