McAfee 8.7.0 falsely identifies an Open Mobile .DLL as a virus (i.e. IEAPMSCHAPV2_64.DLL) and may cause trouble when attempting to connect to an on-campus Wi-Fi network with auth method EAP-TTLS.
To bypass this issue, set McAfee settings to ignore the .DLL. This file is located in the following folders:
Windows 7- C:\ProgramFiles(x86)\iPass\OpenMobile\bin\IEAPMSCHAPV2_64.DLL
Windows XP- C:\ProgramFiles\iPass\OpenMobile\bin\IEAPMSCHAPV2_64.DLL
