Rather than have you change any security settings, lets run a different tool:
Run Microsoft Safety Scanner
Run Microsoft Safety Scanner
- First please Disable any Antivirus you have active, as shown in This topic.
- Note: Don't forget to re-enable it after the scan.
- Next hold down Control then click on the following link to open a new window to Microsoft Safety Scanner
- Click Download Now
- When asked to Run or Save, choose Run. (Unless it's to be run on a different PC)
- OK the User Account Permission or the query "Do you want to run this software".
- If you get a message saying "running this type of program could harm your computer" or similar, just ignore it and tell it to Run anyway.
- Click the box to Accept the license agreement. Click Next.
- Click Next to run the Scan.
- Click the Quick Scan button. (... also Full Scan option)
- Click Next
- (If it finds nothing, it will just Exit. It still does create a report file.)
- If it has found anything, check the box titled "Help Remove potentially unwanted software"
- Click Next.
- (The Dialog label will become "Cleaning your computer"). It may take a while.
- After this operation completes, click Finish.
- When removals are complete, it will report through a link, "View detailed results of the scan"
- Clicking the link will popup a report in Notepad.
- Please post the contents of the file in a reply.
- The report file is also saved here: C:\Windows\debug\msert.log
