Hi Arjohn,
Try using Trend Micro free to use and run for 30 days, best tool;
if no joy there, then try deleting the DLL as an administrator, either using GUI or command-line;
if no joy there, then try a last known good configuration;
if no joy there, then repair OS;
if no joy there, then format and re-install OS and Drivers;
Good Luck!
