This same issue caused my anti-virus program to take over 20 hours to run its complete system scan. I found over 871,000 art cache files that look to come from browsing amazon.com's music store.
I deleted the art cache files by deleting the windows\serviceprofiles\networkservice\appdata\local\microsoft\media player\art cache\localmls folder and creating a new folder witht the same name. To prevent the folder from filling up again with art, I disabled the Windows Media Player network sharing service using the procedure described in this link:http://www.mydigitallife.info/2010/01/27/how-to-disable-windows-7-media-player-network-sharing-service-wmpnetwk/.
Now my slow scan probelm is gone. It took only 3 hours, 15 minutes to run a scan of 750GB internal drive and a 500GB external drive.

Alternatively perhaps you create a batch file to run at Startup or by Schedule Tasks to delete *.jpg files that appear in that folder?
A rough example of a batch file would be along these lines. It would be created in NotePad but saved as a .bat file.
C:
cd "windows\serviceprofiles\networkservice\appdata\local\microsoft\media player\art cache\localmls"
DEL *.jpg
pause
That is only a rough guide and may need plenty of amendments by you as I am not that familiar with batch files but it should not be too hard to do. The batch file when run manually or in Scheduled Tasks would need Administrator privileges or the access permissions of localmls set suitably for the user.

Now my slow scan probelm is gone. It took only 3 hours, 15 minutes to run a scan of 750GB internal drive and a 500GB external drive.
I found 2,037,001 jpeg files in the Localmls subdirectory. This comprised over 70gb of data. Virus scans were taking more than 24hours to complete.
Looking around my computer, I was able to come up with another 24gb of useless files that windows 7 had tucked away.
The big problem here (Other than the obvious problems that Microsoft is not addressing) is gaining access to the LocalMLS Subdirectory. I had to change permissions under several levels of the security tab of the folder properties. This started about four subdirectories above the folder of interest. When I would click the option to change permissions for all objects included, It would change them for all 2 million files, one at a time. This had to be repeated at each level. Make sure to change your power settings to never shut down and go watch a movie or create cold fusion or even measure the significant travel of the Khumbu Glacier while you are waiting for all this to happen.
Wouldn't it be great if Microsoft thought about some of this stuff?
I found an easier way (although it took about 12 hours to finally delete almost 30gb of .jpg files!).
I use Piriform's 'Ccleaner' and there is an item in the cleaner list called 'Custom Files and Folders'. If you check the box next to that, then go to 'settings' and 'include' and add the "windows\serviceprofiles\networkservice\appdata\local\microsoft\media player\art cache\localmls" to the list.
I removed the checks from all the other boxes in the cleaner list, then ran it. As I say, it took 12 hours to delete it all - but at the end of it, that folder is finally empty! When it finally finished, I rechecked the other stuff I usually clear out.
Now the advantages of doing it that way are that ccleaner doesn't stop responding with the task, which explorer did on my machine. Plus the setting is now there - no batch file necessary. It will clear the folder every time I run it.
