I have free avast running on a windows 2000 system. Every time avast wants to update the virus database, it ends up with an error message: There is not enough memory space for this command. But there is 27 GB free space on the system volume. Is there anybody who knows what to do?
The avast program version is 8.0.1506
The problem is the obsolete version of avast that you are using.
Time to update the OS and avast.
That version of avast is no longer supported.
Follow Eddy’s advice and upgrade everything.
