2. In the wizard window, select Roll back changes and click Next.

When you use the Internet or standard desktop applications, files are saved in the system with the following information about your activity:

• Browsing history 
• Search queries 
• Information about started applications and edited files 
• Microsoft Windows event log entries 
• Temporary files 

These files may contain sensitive information, such as passwords, which is why we recommend that you regularly clear such files.

To clear user activity logs:

1. In the main window of Kaspersky Internet Security 2018, click More tools.

1. If you have problems opening the application window, see this guide.

2. Click Show 4 more.

3. Select Privacy cleaner.

4. In the Privacy Cleaner window, select:
   • Search for user activity traces.
   • Roll back changes (the option is available if the wizard was used before to delete information about the user's activity)
5. Click Next.

6. Wait until the search is completed. 
7. Select the checkboxes beside the actions you wish the Wizard to take and click Next.

8. Wait until the traces are cleaned.
9. Click Done.

If you run the wizard once again, it may detect activity traces you have already cleaned. Information about user activity is constantly accumulating in the system. For example, the Microsoft Windows log file may be used by the system when the wizard tries to remove it. To remove this file, the wizard will prompt you to reboot the computer. The file may be created again while rebooting, in which case the Wizard will detect it once more the next time you run a search. 

After a malware infection, traces of malicious objects are left in the system. For example, the operating system security settings might be incorrect, file extensions might have been changed, access to the Control Panel might be blocked, etc. Troubleshooting after an infection removes any malicious files or damage left behind by malware, as well the consequences of any system errors and malfunctioning optimization software.

To run the Microsoft Windows Troubleshooting Wizard after an infection:

1. In the main window of Kaspersky Internet Security 2018, click More tools.

• If you have problems opening the application window, see this guide.

2. Click Show 4 more.

3. Select Microsoft Windows Troubleshooting.

4. In the window, select an action:
   • Search for damage caused by malware activity
   • Roll back changes. This option restores the system to the state it was in before the Microsoft Windows Troubleshooting Wizard made any changes. This option is only available if the Wizard has made changes previously.
5. Click Next.

6. Wait until the search for problems is completed. 
7. Select the checkboxes besides the damage you want the Wizard to fix, and click Next.

8. Wait until the application is installed, and click Finish.
