Thanks again, Alan.

PS: I don't expect to proceed further until Monday pm (Tuesday 31 March in Oz).

Hijackthis log is clean

Hi crunchie,

Excellent. Do you ever sleep?

I guess I should delete my earlier system restore files now, although I think the infection blocked or corrupted these files anyway.

Thanks again for your time and help, Alan.

I guess so, I just woke up . No worries.
