Immediately after they finished with my machine I began receiving spam, so much so that my ISP shut down my email. This company will "scan" your files but I suspect they are actually down loading them. They will try to sell you a monthly service and about all that is done for your computer is a standard defrag. I would suggest changing passwords if you have let them into your machine. For this "service" you will be billed $39.95. I strongly suspect fraud and phishing are the real goals of this "company".
