Issue with HP QuickDock 2.0 on HP DV7 running Windows 7 - Randomly Mounting/Unmounting

Question

Greetings!  
I recently purchased an HP QuickDock 2.0, because I have two external harddrives, a USB charger for my phone, and a printer attached to my laptop just about all the time.  
The dock works great usually, but several times a day, it will randomly unmount and mount itself, which in turn causes my hard drives to do the same (not good - I have experienced some data loss as a result).  I've tried updating drivers, searching high and low on support forums, uninstalling in Device Manager and letting it reinstall, etc.  No success yet.  
The only thing that looks fishy in the device manager is a yellow caution triangle beside "WD SES Device USB Device" under "other devices."  For whatever, reason, it isn't finding a device driver for one of my externals now that the dock has been installed (was not like that before).  I've tried to uninstall the device and let it try to find the driver again.  No luck.  Odd thing is, both of my harddrives still function perfectly, even though one apparently does not have a driver.  The WD SES problem did not exist prior to installing the dock.
I've downloaded and installed these drivers (http://cid-cafafbf93acdb073.office.live.com/self.aspx/.Public/Drivers/HP%5E_USB2%5E_docking%5E_stati...).  No change.  
I'm not sure what else to try.  Any suggestions?

This is definitely from malware - it happened to me last night and I checked online and found 2 many guesses. I managed to resolve it moments ago - and I'm typing with the same computer / keyboard.  It is hard to resolve but here is the link to the virus description (which does not mention the specific symptom of losing the 2 W S X keys). I lost the function immediately, and suspected malware right away: http://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=TrojanDownloader%3aJava...
So this is how I solved it: I had Microsoft Security Essentials and it was up-to-date. However, it does not find it by itself. Spybot finds something but is unable to fix it - even upon a reboot. I installed Trend free atHome(?) virus scan - it does not find it. I installed AVG full Internet Protection - it does not find it. However, while AVG was running (a few hours) Security Essential found it - just like that! So, it appears that when the malware was adjusting itself to avoid being detected, that it was discovered by MS Security Essentials. I fixed it while AVG was running, and tested my keyboard right away. At first the x worked, then the other keys.
This is malware - not hardware, so please stop telling people to clean or replace their keyboards.
