Please follow the instructions in This Guide
starting at Step 6
Once the proper logs are created, then make a NEW TOPIC
and post it HERE
Please include a description of your computer issues and what you have done to try to resolve them.
If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.
Please also paste your ComboFix log in the new topic.
