Download GMER Rootkit Scanner from here to your desktop. It will be a randomly named executable.

Double click the exe file.
If it gives you a warning about rootkit activity and asks if you want to run scan…click on NO, then use the following settings for a more complete scan.

Click the image to enlarge it
In the right panel, you will see several boxes that have been checked. Ensure the following are unchecked
- IAT/EAT
- Drives/Partition other than Systemdrive (typically C:\)
- Show All (don't miss this one)
Then click the Scan button & wait for it to finish.
Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file which cannot be uploaded to your post.
Save it where you can easily find it, such as your desktop, and attach it in reply.

Rootkit scans often produce false positives. Do NOT take any action on any "<— ROOKIT" entries
