General Anti-Virus Questions

[Spiritual2016]

Please answer each question:

1. Is an anti-virus program 'active' if the computer is disconnected from the Internet but left on?

2. Is an anti-virus program 'active' if the computer is turned off but left plugged in?

3. Is an anti-virus program 'active' if the computer is turned off and unplugged?

4. If a computer is disconnected from the Internet at one location and re-connected to the Internet at another location, does an anti-virus program 'automatically' detect an Internet connection and become active?

1. Yes
2. No
3. No
4. An anti-virus is always active running real-time in the background when the computer is on (assuming one is installed). The internet connection is just needed for the virus database updates and cloud features.
