I have not done any actual tests, so this is just observation and opinion. It has not been to intrusive, has regular definition updates (like three or more a day), and works with Windows 8.1 (version 220.127.116.11) with no noticed anomalies. It is a pretty simple interface and easily (for me) configurable. It has stopped all (so far) baddies I have come accross. You may need to adjust the web page blocking and spam filtering to suit your needs. However, if, you want a lifetime licensed solutions... this one seems to be a decent deal. You can get a 30 day trail version and test it for yourself, if you wish to.
