What is your VPS version ? Current VPS is 130501-0

I do not have any problems. Could be a server issue at your location. If this have been happenig for a while now, you could try reparing Avast!.

Start > Control Panel > Programs > Programs & Features > uninstall a program > select avast! and click " Uninstall/Change ". Look for " Repair "

Reboot when finished.
