Thanks Brad,
I did that, rebooted and the problems disappeared... (I did another scan with HJT and all the dodgy-looking entries seem to have been removed)
... But, when I disconnected from the 'net I got a strange error message saying that Internet Explorer had a fault running scripts...
and sometime between then and now, the problem with the resetting homepage seems to have re-appeared!
When I open IE the homepage resets to a file on the C drive simply called 'Homepage.htm' (it's a link to some weird search engine which also sells insurance!! ).... I tried to delete this file but got a message to say that it's a system file and removing it could cause problems.
So, I did yet another HJT scan and by the looks of it, the problem entries seem to have re-appeared too!
here: (again, apologies for the longgggg post!)
