You will be prompted to reboot your computer.  Installation will occur remotely, and once it is finished, it will require a restart.  A pop-up window like the one below will appear.  We suggest restarting your computer as soon as possible; however you will be able to postpone the restart until later the same day.

What is it?

IPS technology prevents malicious files from getting to your hard drive in the first place.  Unlike antivirus, which looks for known malicious files, IPS scans the network traffic stream in order to find threats using known exploits and attack vectors. IPS does not detect specific files, but rather specific methods that can be used to get malicious files onto your network. This allows IPS to protect against both known and unknown threats, even before anti -virus signatures can be created for them.  IPS is very good at detecting “drive-by” downloads of malware and fake antivirus scanner web pages, which Auto-Protect cannot prevent. In today’s complex threat environment, this technology is an effective complement to antivirus technology, and its usage should be considered a necessity on any network that is connected to the Internet.
