CCleaner is one of the most popular Windows registry cleaners on the market, giving you a quick, easy, free way to keep your computer in tip-top shape. Sadly the latest update (5.45) has introduced a new feature called Active Monitoring, which among other things, actively collects system data to feedback to Avast. Although the feature is enabled by default and disable resistant, it can still be removed, so follow along as we guide you through the process.

As mentioned in the introduction, CCleaner is one of the best registry cleaners on the market and has a ton of other tools to help keep your system clean and organized. Sadly though CCleaner has recently updated the free version to now include Active Monitoring, a new feature to monitor your system and provide notifications for updates as soon as they become available.

Although this may seem like a helpful feature, its main purpose is to gather and send user system data (anonymously) to Avast, their current overlords. Apart from this, CCleaner Active Monitoring doesn’t really provide anything of substance and is just another pointless background process burning through resources on your system.

For example, the average Windows user is already running Avast/AVG for antivirus, Malwarebytes for malware protection, and ZoneAlarm as a firewall. On top of this, most users have several other programs to start on system boot, Steam, and Origin as two example. With all these tasks planned to start when your system does, you can expect slow boot times, even when using the latest SSD and Ram tech.
