Do you still need help? If you do, please follow the directions below.

The first thing I will need you to do is to go to this link and follow the directions precisely. If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line. If you can't run any step, just jump to the next one. Please let me know how you are doing or have any questions. Initially, I will need the SuperAntiSpyware, MBAM and HJT logs. Please post any logs that you can generate.
