Overlook is a potentially unwanted program, or PUP, that is commonly bundled with other downloads. When installed, Overlook does not create any Start Menu shortcuts or Desktop icons. In fact, the only way you would know it's installed is that you may find it listed in the Uninstall Programs control panel. What you will notice, though, are the following symptoms:
- Your computer will be running very slow.
- Your computer's CPU utilization will be close to 100%
- You will find numerous tasks called Navigate.eXE running under a Runner.exe process in Task Manager.
- Applications and Windows will freeze.
- Your Internet may be slow.
This is because in the background, there is a process called Runner.exe that is constantly launching instances of its bundled Chromium browser to access web sites. The Chromium processes that are launched will be either named Chrome.exe, Navigate.exe, or Navigate.eXE. The purpose of all these web requests is unknown, but the byproduct of all these requests is your computer is running slower than it should be. It is important to note that the Chrome program bundled with Overlook is a legitimate program and not malware or a PUP.
When installed, Overlook will create two tasks in the Windows Task Scheduler called Updater for Analytic Tool and Worker for Analytic Tool. The Worker for Analytic Tool task will start Overlook every time you login to Windows and will continuous check to make sure it is running every ten minutes. The second task, Updater for Analytic Tool, will run every 6 hours and download new configurations or instructions for Runner.exe to use.
As you can see, this program will instead use up your computer's resources without your permission or knowledge. It is therefore important to remove this program so that your computer will be running properly again. Furthermore, if this program is installed on your computer there is a very good chance that other PUPs are installed as well. Please use this guide to remove all remnants of the Overlook PUP and any other related programs.
