Hello
I’m using Avast on a Windows XP SP3 Laptop and in the last few days the signature updates fail most of the time with the error message “'Not enough storage space is available to process this command”.
However the PC has 8 GB of SSD storage and about 2/3GB of Ram left.
Is there a way to find out the exact reason for the failure?
See this thread:
Wait for avast update for the fix bugs or you can try to clean uninstall then reinstall the latest version of the EP Client

Still not working. 
Yeah, I can confirm that the new Beta version also doesn’t solve this problem for us.
Beta to neopravuje!!!/Beta does not fix it! >:(
Is anyone out there affected by this issue on Windows 7+?
