Don't use this company! One of our computers was freezing and we spent $300 to get the Cyberdefender software. Not only did they screw it up so bad that our internet stopped working and the computer started to freeze up even more, but we couldn't get in touch with the billing department to get our money back! We had also had them "optimize" another laptop in the household and they had it messed up to where it stopped recognizing my iphone, couldn't download microsoft updates anymore, and would just loop itself from startup and then shut down over and over! I couldn't even get to the desktop! I have to go get a external back up so I can get my pictures off of it so that I can do a complete system recovery! (which means that I have to format the entire computer back to factory state. Thank God my computer has that option!) So far, I've been on hold with them for 45min-1hour, and finally gave up on actually talking to the billing dept. They say since I have the $300 plan, I have to talk to THAT specific billing department for a refund. I've decided that that dept. Dosen't exist, and they just put you on hold FOREVER till you hang up. Let me say again people... DON'T USE THIS COMPANY! They will screw up your computer and if you try to get your money back... You'll be outta luck!
