content: Absolutely.  I've looked at it and used it with no ill effect, and it is effective.  We have to continue to be vigilant as Microsoft uses polymorphism to evade detection, so with every Patch Tuesday I wait to see if there's a new aegis version and apply it. It's not a good idea to stop all updates, as there are security issues.  Aegis does a great job of keeping out the malicious updates and allowing the useful ones to install. Thanks, /u/thepower!
