Question : explorer.exe is using 90-100% of each CPU

Hi Experts,

I am running Windows 7 Ultimate 64-bit on a 4 core CPU.

Sometimes I look at Task Manager and explorer.exe is using 90-100% of each CPU.
How can I determine what is causing this?

Regards,
Leigh

This is a shot in the dark, but snxPlugins64 seems to be related to avast. That could be what's eating up your CPU. Could you try uninstalling avast to see if that resolves it? If it does, you should contact Avast about the issue, to see if they have an updated version - or you should try another antivirus program.
