My Acer Aspire 7741 Laptop Not Shutting Down

Hi All,

Hope you can help me please. My Windows 7 laptop won't shut down normally. The screen shows it's shutting down but it just continues on and on.

I Have to remove battery to close down. (Not good)
Start up is also quite slow. When it's running everything seems to work normally. Not slow or sluggish.

I have Kasperky Internet Security. I do regular scans using Malwarebytes, SUPERantispyware & Kaspersky.

I would appreciate any help anyone could offer.


Thanks



Pete
