Hijackthis.....hosts problem

Midway through the scan the message as in attachment appears. However having followed the instructions and locating the hosts file (or in my case not, as it is not to be found), the final stage "saving hosts including quotes fails with "Access Denied".

I have checked permissions and they show in grey that a, user/administrator, I have full rights.
Otherwise the resulting list seems to populate normally.

Can anyone, please, suggest what the problem may be, or what I may be doing wrong?

Might there be a similar app to Hijackthis without the snag?

Here is an older thread from these forums that may shed some light on your issue and offers some sage advice: problem with Hijackthis on Windows 7 pro 64 bit

Thanks!:) So "sayonara HJT"

Not in particular, but location has had problems from local substation/ transformer. played havoc with internet connection. Though now cured by lots of men in hard hats, actual download times have been sluggish.

I just wanted to see if anything strange had got in despite using various known security s/ware incl paid M'bytes.

Using another prog I found something and it's now gone. ATM the sluggishness is gone, so for now I don't think I need go further.
