user811,
Firstly, the language used on this forum should be suitable. Your immediate "inflammatory remarks" (modified text from earlier post) of Avast were not necessary.
Ashserv.exe is a file which Avast uses as part of its' functionality, and allows the user access to scanner functions and also assists in the ability to check for update/s to the vps database files and program via the systray. If you were to "open" the ashserv.exe file manually, you would see an additional instance of A and I ball icons in the tray.
It is necessary for Avast to write to the hard drive or wherever Avast folder is located.
Avast contains NO spyware or malware of any kind.
Some anti-spyware programs of which one was mentioned, will report Avast as spyware. This is not true and are most definetly false positives.
Adaware and Spybot S and D are good programs, but be cautious of removing all the listed files in the Spybot scan. It sometimes reports necessary files. Adaware is not known for such nonsense.
Allow Avast to make its connection. You will be secure.
Good luck.
