Adding contacts in outlook 2010 is very slow. Avast addin is slowing it down.

Hi Guys,

We are using Avast end point protection suite.
Issue : adding contacts is very slow in outlook 2010. I investigated and found that when we disable avast addin in outlook, it is fast but we can’t disable avast addin in outlook for security.
We are using win7 64bits. Help plz
