If you are experiencing problems with your computer and you think it might be caused by a virus, then you should take it to a computer specialist. However, if you are not sure whether the problem is caused by a virus or something else, then you can try deleting the Dpf file. To delete the Dpf file, open your computer’s Start menu and select “Run.” Type “cmd” and hit enter. Then type “dpf” and hit enter again. The computer will ask for your password, which you should remember. After typing in the password, click on the “OK” button. Now that the Dpf file has been deleted, your computer should be back to its normal state. If there are any problems remaining after deletion of the Dpf file, then they will need to be fixed by a professional computer specialist.
