All LCPH computers have Avast antivirus installed. This software will help keep systems from downloading malicious software, visiting malicious sites, and opening malicious emails. You should always make sure your antivirus software is installed and functional. Its main indicator is located in your Windows system tray. 

The icon for avast looks like a little orange ball:  

If you hover over the avast icon it will indicate if everything is running correctly: 

If for some reason there is a red mark on the orange ball or when you hover over the icon, you're presented with a Red popup that states there is a problem, please submit a ticket as soon as possible.
