Updated versions are: 4.1.289 and VPS (virus database) 0311-0
ashserv.exe manages and implements avast! antivirus services for this computer. This includes the resident protection, the virus chest and the scheduler. aswUpdSv.exe is avast! iAVS4 Control Service, which provides automatic updating for the avast! antivirus. The answer for your questions are: the file itself could be updated since your version are not the last one. Right now, this file does not need to access the Internet (at last, in my system it never asked for. I just have: avast.setup file and avastmaisv.exe (the mail scanner).
Also, I think I had my internet lock on at the time which may have caused the alert.
Manually update could inform (and download) you about the new versions. The last one is 4.1.289 (see About dialog from the tray icon ‘a’).
Could you explain a little bit more?
Definitevely not.
Have fun and luck. Technical.
