how do i get past internal compiler error?

I keep getting this in the log whenever I pretty much do anything. First I was trying the ball rolling tut and couldn’t save the script, after uninstalling unity then re-installing, I am attempting the space shooter tut. I get the assets imported from the store, and this popped up. I have disable my real time antivirus, I have full permissions, and yet I still can’t figure this out. I am very new to this whole thing but would like to continue learning, if someone can help me get past this I will be so grateful.

Internal compiler error. See the
console log for more information.
output was: (Filename: Line: 0)

There could be many reasons most common is that you have antivirus program blocking monodevolp’s
files. or it could be a minor glitch try re installing unity or in some cases it may be lack of updating and depends what coding language your using sometimes c# gets the public class wrong from the name please give the full error so we can help you more
