Normally this process is safe: http://processchecker.com/file/wlcommsvc.exe.html

But there can be a virus involved…or more probably an attacker tried to see your OS was vulnerable to be compromised and avast! stopped that!

This is a feasable method.
Uninstall the present version, then downlaod a new version , but do not download the Chinese version from China…
方法,在C:\Program Files\MSN\Service下分别新建两个记事本,并分别命名为1.cmd和2.cmd

call 1.cmd

&

del wlcommsvc.exe /f/q/a
call 2.cmd
