Yes I updated to Adobe Reader 11.4
Try this:
On start menu, type "msconfig"
on Startup tab check if you can find an entry "sysTPL.exe" and disable it.
on Services tab check if you can find "sysTPLService.exe" and "sysTPLMonitor.exe" and disable them. Then restart your PC.
If you can't find them, just restore back your PC to the state before you did the update. Something else got installed in your PC without your knowledge.
