Yahoo Update Manager – YVERINFO.DLL
Yverinfo.dll and yverglance.dll will be found in your c:\Program Files\Yahoo\Common\ folder. These ActiveX controls install with Yahoo Update Manager. The Yahoo Update Manager checks to see if there are updates available for any of your currently installed Yahoo Programs including Yahoo Messenger. If you want this to happen, leave these files in place.
There is a security vulnerability involving these files. You can learn more about it at http://www.verisign.com/security-intelligence-service/current-intelligence/vulnerability-advisories/2007/591.html. Yahoo has fixed the problem as of their August 29, 2007 ActiveX update. You'll find that at http://messenger.yahoo.com/security?id=082907.
