Generally, all error codes under 30,000 (decimal) are system (Windows) error codes.
First, translate them to the decimal form from hexadecimal (use e.g. Windows calculator to do this) and then use the net helpmsg Windows command to find out what the error means.
Example: avast reports error 0000007E. You run calc.exe and convert the hexa number 7E to decimal – the result is 126 decimal. Then you start the command prompt (cmd.exe) and type
net helpmsg 126
which gives you the description of the error (in this case “The specified module could not be found”).
Hope this helps,

as u see he took your error as an example…
the error is The specified module could not be found
my guess is that avast didnt install correctly on the system, try fixing it or reinstalling
AV software is in such deep installation with hooks to be possible to scan as much as possible that it needs to be unloaded with a reboot of the server
when you (un)install software like antivirus or firewall software, nomather what it is best practice to reboot the windows computer
