The Internet Explorer popup it's probably related to the Adware we removed. Resetting Internet Explorer to the default configuration should fix it.
The SFC scan also found some problems on files related to Internet Explorer, although you do not use IE the browser is deep integrated with Windows 7 and running an outdated version of the program will make your system vulnerable. I recommend you the following steps:Step 1 - Reset Internet Explorer
- Close all Internet Explorer and Explorer windows that are currently open.
- Start Internet Explorer.
Note: If you are running Windows 8, start Internet Explorer for the Desktop. Changing your settings will affect both Internet Explorer and Internet Explorer for the Desktop.
- On the Tools menu, tap or click Internet options. If you don't see the Tools menu, press Alt.
- In the Internet Options window, tap or click the Advanced tab.
- Tap or click Reset.
- In the Reset Internet Explorer Settings dialog box, tap or click Reset.
Select the Delete personal settings check box if you also want to remove browsing history, search providers, Accelerators, home pages, Tracking Protection, and ActiveX Filtering data.
- When Internet Explorer finishes applying default settings, tap or click Close, and then tap or click OK.
- Exit and then start Internet Explorer.
