i was having a problem with anywhere folder and was online deleting a few files, when windows flagged up no anti virus installed, i never did anything honest?? Webroot had gone.
Are you using any other security software which could have removed WSA, or did you send any commands down from the central console?
no other security on, maybe i did send something would deactivating a computer do this, i re installed windows on the family laptop, although i named it the same i had 2 entries, so i deactivated on
That could definitely do it. Deactivating a computer will take protection off (and I believe it triggers an uninstall as it would just reactivate the next time it checks in).
