Problem regarding Firefox 12 URL Advisor/Virtual Keyboard & Anti-Banner

Hi experts,
I am having a problem regarding Firefox 12 URL Advisor/Virtual Keyboard & Anti-Banner sorted by patch C.
Although it started working, but it did not perform successfully. Compatibility issue might have occurred.
While running Kaspersky pure password manager for Firefox 13, I got the error message like this.

Error

An error occurred while trying to rename a file in the destination directory:
MoveFile failed; code 183.

Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.

Do you have any idea regarding this issue? Please help me.
Thanks in advance.
