Query: Terrible

Downloaded first for my notebook, this was okay although it dramatically slows down machine, why is it it needs to do a virus scan of a document already held on your machine?( Assuming already done full system scan and scanning all mails)Then downloaded version for desktop then my nightmare from hell started and whilst reasonably PC competent it was far too deep for me in what it was doing to my machine.It was bloody murder, nothing worked or if it did it took 3 minutes to open a file.My mail went AWOL and when i checked the status window it told me I had an error in the E mail setting but no idea as to how to fix it. User support was a joke ( especially from the UK) and now i decided to forget the money spent, do a system restore ( it didn't like it) to before i bought it and now wouldn't dream of letting it get near my machine again.Be warned!!!!
