Deep scan taking forever to complete

I am in the process of running my first ever deep scan.  It has already run for 6 hours and I am only at 47%.  What could possibly be the problem?  Nothing seems wrong with the function of my computer.
Any help appreciated.

Hi Brian,

We're glad to look into this & help you.
Please let us know the operating system of your computer, for how long the scan was at 47% & clarify whether there is a progress in scan currently.
We'd like to clarify that the 1st deep scan will usually take some time depending upon the file size on your computer.
