Windows 7 Desktop Icons Slow To Load

On the Win7 (64-Bit) I notice lately that the desktop icons are slow to display. They start with 'white boxes' and then slowly they fill-in with the correct icon.I tried the following, and now the icons show right away, but then the screen blinks (for lack of a better word) and the icons show as 'white boxes' and then in a second or two they return to the regular (colored) icons. Anything else I can do to make the icons appear as fast as they did orginally and stay that way rather than turning "white" and then changing back to the regular colored icons?

1. Close all folder windows that are currently open.

2. Launch Task Manager using the CTRL+SHIFT+ESC key sequence, or by running taskmgr.exe.

3. In the Process tab, right-click on the Explorer.exe process and select End Process.

4. Click the End process button when asked for confirmation.

5. From the File menu of Task Manager, select New Task (Run...)

6. Type CMD.EXE, and click OK

7. In the Command Prompt window, type the commands one by one and press ENTER after each command:

CD /d %userprofile%AppDataLocal
DEL IconCache.db /a
EXIT

8. In Task Manager, click File, select New Task (Run...)

9. Type EXPLORER.EXE, and click OK. =====================

After the icons show the first time (when computer is turned on), I notice the MSE icnon in lower right has a red X on top of it and when the X goes away (in a sec or so) the icons turn white and then in a second go back to their ususal color. If I click on the MSE icon (with the red cross on it) the MSE will open and in RED it states "Real Time Protection is Not Turned On." And then in a second or two the Red Cross goes away and the the wording turns Green. I think there might be something wrong with the MSE or it does NOT work well with Win 7 64 Bit. Maybe I should do a System Restore, to remove MSE and get back AVG?
