Note: The computer's antivirus program may report FRST incorrectly as an infection.
If so, disable the real-time protection when downloading and running FRST.
Right-click to run the tool as administrator.

When the tool opens click Yes to disclaimer.
Note: Ensure that the Addition.txt check box is checked at the bottom of the form within the Optional Scan area.
Press the Scan button.
Please wait for the tool to finish.
It will produce two logfiles called FRST.txt and Addition.txt in the same directory the tool is run from (which should be the desktop)
Post the logfiles FRST.txt and Addition.txt as attachments in your next reply.
