You only have to enable the MyAvert Securty Threats when configuring a proxy server if you are configuring a proxy server for the MyAvert Security Threats task. If you are configuring a proxy server for the repository pull then you would do it on the Software | Configure Proxy Settings page in EPO.
The MyAvert Security Threats task is used to popluate the Master Repository Status report on your dashboard. Essentially it provides the latest available DAT file so you can tell if your repository is up-to-date and it also provides some information on the latest security threats. The default interval for this task is 15 minutes.
