Startup svchost.exe takes15-20mins

[1vincent]

Hello.

When i start my computer from the time it starts to the time i can start to use it takes over 15 mins.
svchost.exe is using nearly 100% all the time. It is netsvcs group that is using the cpu.
I have done av scan,malwarebytes,super anti spyware and spybot and they all came back clear.
I am using Windows ultimate for 2 years and i think this has only started 3 weeks ago when it became very noticable to me.
Any ideas very welcome.
Vince

Have you updated any drivers or added new programs, USB devices?
What AV do you use?

I use ESET smart security.
3 weeks ago my wireless broadband was very slow and disconnecting alot. Used issider and there was a neighbour using the same channel as me so i put in a wireless usb dongle which was a bit better. The computer was the same then as it is now. The drivers are upto date as is windows 7 and no new programmes installed.

I have rechecked all my drivers and they are all upto date.
Have done a windows update and none were needed.
Run AV checker, Malwarebytes and Superantispyware and these all returned no problems.
