If I were you, I would disable both Avast and Norton. Avast constantly updates multiple times a day and slows you computer down every time it does. Furthermore, Avast lies to you about viruses. It once told me multiple times I had a rootkit on my computer, yet, it scanned the file and found no rootkit at all. Even after that, it constantly alerted me of rootkits that I did not have.

Avast is not an antivirus program, it's a poor attempt at mimicking GLaDOS. I was told to never download any trials of the full version of Norton Internet Security, and to avoid downloading it at all. Many people have said how Norton can permanently damage your computer beyond repair, to the point you have to go buy a new one because the other one doesn't work.
