Today I was using DC++ (v 0.6.7.4) and got a Microsoft Visual C++ Runtime Library message that a buffer overrun was detected and the program had to be terminated. The error repeated upon re-starting the application later on. This is the first instance of this in over 7 months of using DC++.

Ad-Aware and Spybot detected no threats, XoftSpy found a "KeyCaptor" instance. CW Shredder located "CWS.Hiddendll". AVG Free (v 7.1.392) found no viruses. I am using ME with all recent updates (I know ME is less than ideal but an upgrade is less likely than a new system purchase).
