Unity 3d Unhandled Exception: System.UnauthorizedAccessException

Question

I am new to Unity. I am getting this error from time to time in Unity ever since I am using it. It says : Unhandled Exception: System.UnauthorizedAccessException: Access to the path "C:\\Users\\MyPC\\Desktop\\Folder\\ProjectName\\Temp\\Assembly-CSharp.dll.mdb" is denied

I tried googling, but to no success. I do not get this error on my office PC.

I am using Windows 8 laptop. Have Avast antivirus installed. Unity version is 5. Android sdk version is 2.2.

Reimporting all assets did not help. Even restarting Unity does not stop the error. I have even tried uninstalling my antivirus(though that's a risk), but no use.

Answer 1

1. Close unity (check Task Manager to make sure there are no unity instances floating around)
2. Navigate to that particular \\Temp folder using Windows Explorer,
3. Delete all files
4. Restart unity
