Chrome has an estimated user base of 2.7 billion users, making it the most popular web browser in the world. But this important user base also makes Chrome an irresistible target for hackers. The good news is that you can use Chrome’s built-in CleanUp tool to remove unwanted adware, pop-ups, and other types of malware.
All you need to do is navigate to Settings → Advanced → Reset and clean up → Clean up computer → hit the Find button.
How Long Does It Take for Chrome to Check for Harmful Software?
After you launch the scan, the “Checking for harmful software…” notification will pop on the screen. Chrome generally takes two to five minutes to check for harmful software. You can speed up the process by clearing your cache first. If the CleanUp Tool detects any suspicious programs or extensions, it will prompt you to remove them.
Unfortunately, Chrome may sometimes fail to check for harmful software. Let’s see how you can fix this problem.
