Block popups and unwanted changes to Chrome settings
If you're seeing pop-up ads that won't go away, or you suddenly have a homepage that you know you didn't set, you may have an unwanted program installed on your computer. Here are some steps you can take to get rid of this program and block similar ones from getting installed in the future.
Look for malware and unwanted programs
Here are some clues that a suspicious program is affecting Google Chrome:
- Chrome doesn't block pop-up ads from showing.
- Your homepage, startup page, or search engine has changed to a site you don't recognize
- Unfamiliar extensions or toolbars are added to Chrome
- The Chrome desktop shortcut opens an unfamiliar website
These changes may be caused by malicious software known as malware. You can get malware from downloading files or visiting insecure sites. If you’ve found a site that you think has malware, report the malicious site.

Step 1: Get rid of unwanted programs
You should remove malware and other programs on your computer that you don't remember installing. You have to uninstall malicious programs before you can get your Chrome settings back to normal.
Windows users: To help find these tricky files, you can download and run the Software Removal Tool. It’s an application that searches your computer for suspicious programs and offers to remove them for you.

Step 2: Reset your browser settings
After you have removed malicious programs from your computer, reset your Chrome browser settings. Your current bookmarks and passwords will not change, but you'll need to customize things like your startup page, search engine, and browser theme again.
Note: If you use the Software Removal Tool, it will take you through the following steps automatically.
- In the top-right corner of the browser window, click the Chrome menu
- Select Settings.
- At the bottom, click Show advanced settings.
- Under the section "Reset settings,” click Reset settings.
- In the dialog that appears, click Reset.
Settings that are reset:
- Default search engine and saved search engines will be reset and to their original defaults.
- Homepage button will be hidden and the URL that you previously set will be removed.
- Default startup pages will be cleared.
- New Tab page will be empty unless you have a version of Chrome with an extension that controls it. In that case your page may be preserved.
- Pinned tabs will be unpinned.
- Content settings will be cleared and reset to their installation defaults.
- Cookies and site data will be cleared.
- Extensions will be turned off.
- Custom themes will be removed.
