I'm having Scan probloems.

First thing that happened was the quick scan completed but it wouldn't let me fix the tracking cookies. I had to restart the computer and it worked then. The next day I tried to do a quick scan and recieved a message saying there was an internal error. I tried it a couple more times including a full scan. I recieved the same internal error message. I restarted the computer and it worked then. It quit doing it for a few days. Today, it was doing an automatic full scan. I got the same error message. It had scan long enough the it detected tracking cookies. I tried to go ahead and take care of them but it said it failed. Also it said the frame work has stopped working. Each time I get the internal error message it tries to connect me to the internet. I don't know why and I'm not sure I should let it. I get updates fine. Most of the time scans work fine. And whenever I restart it I don't have to do it again that day. It only seems to happen once a day if at all.

 

Is anyone else having this problem? What should I do?
