Avast internet security can't browse , can't access a shared document

[zillah]

Dear folk

Avast forum wasn't able to provide advice on my issue

I have avast internet security installed on Desktop windows 7.

Desktop  is acting as home server (i.e shared drive, shared printer )

My other two laptops can't ping the desktop unless i have to disable Avast ,,,,sometime my email client on desktop won't work unless I have to disable avast

Recently laptops can't print to my usb printer that was shared via desktop

Thanks

what did the Avast forum members suggest?

I did what they asked me to do but till now no cure

just confirming, your email and browser issues have been fixed and it's now just the shared folder that cannot be access across the network?
but it does work if Avast is disabled?

Beileve i don't know what to tell you
Sometimes email and internet browsing work sometimes not.
With Shared folder i can't ping LAN ip address if i disable Avast i can ping LAN
