Running windows 7. When browsing using firefox, received message that I should contact comcast when opening link to yahoo mail. Ran malwarebytes and spybot, nothing found. Deleted a bunch of old and unknown programs using uninstaller. Seemed to work fine. Then, wife was using Chrome to browse and was getting pop-up errors. Shut chrome and used firefox to look for other programs to clean up computer. Came to bleeping computer, downloaded adwcleaner and combofix. Ran combofix not realizing it was supposed to be used with guidance. I have log if someone could review.
