Using Vista. I have just removed Kaspersky 2010 and updated it to version 2012. Installation was no problem and program seems to work OK. However since installing Kaspersky a Windows Explorer window opens overlaid by a message saying 'Drive I' cannot be found. I don't have a 'Drive I' on the computer - only C, D E and H (a hard drive used for backup, all working satisfactorily. Cancelling the message does not help. It reappears within 15 seconds. Any ideas?
