Norton 360 Quick scan - very very slow/ not finishing

Hello all,

 

I have been trying to run a 'Quick scan' with Norton 360 over the last couple of days and the scan is very slow.  It usually grinds to a halt around the 1,700 file mark - then ticking over a file every few minutes.

The longest I allowed it to run was 6 hours before rebooting (it was slowing the my machine down). Norton 360 now says my machine is at risk because I have not done a scan.

 

Whilst doing the quick scan it seems to spend most of its time (many minutes) on individual HKEY_USERS\... and other HKEY_...\... type areas and files.

 

The last quick scan was on 16/6/2014 with no problems found.

 

I've run liveupdates a few times - it is up to date and I have rebooted several times.

Tried Support: get support. Everything ok

 

Downloaded and run the NPE - no problems found

 

I've done an on-demand scan on the whole OS (C:) disk  - no problems found (and fairly quickly scanned the thousands of files!).

 

No other security software is installed/running on the machine.

I have tried what was suggested here (turning off compressed file scan) but that hasn't worked.

Any other suggestions. Given my Norton subscription is up for renewal next month it would be great to get it working again.

 

Cheers

Gareth

 

p.s. my machine is a eMachines netbook running Windows XP, and Norton 360 has been, up to now, working fine over the last couple of years.
