Answer 1

AVG Resident Shield
As far as I'm aware, it is the monitoring portion of AVG anti-virus program. It runs continously to monitor your computer for possible viruses and infections. If it detects anything, you will receive an alert indicating the problem and the suggestion to run the anti-virus program. The resident shield does not remove viruses though, just warns you that it has found something. You have to run an anti-virus program to remove it or find it yourself and remove it.

Here are more opinions and answers from FAQ Farmers:


Actually, it monitors files you click on, or that are started by other programs, and keeps the virus from executing, it will then automatically give you the option to repair or delete the file.

Resident Shield is protecting the computer whenever the OS is running. It is working in the background and ensures transparent anti-virus file check during file opening, executing and optionally during file saving. Resident Shield runs automatically. If a virus is detected, Resident Shield denies opening or running of the infected file. Resident shield stores information about files it has checked elevating the need to recheck them if no modifications have been made.
