I have just installed ClamWin on two PC's . OS are XP Pro and Vista Home Premium. When I manually scan both default to scan D drive and not C to Scan C I manually change to that drive. Once I log out and reboot the default drives revert to D on both PC's. On the XP PC D drive is a cd/dvd drive on the Vista PC D is a small HD on which I store jpeg pics and letters. When ClamWin scans automatically my educated guess is D drive on both PC's is scanned on the XP there would be no cd/dvd in the drive on the Vista PC there are only data files which are seldom updated. The heart of the systems namely the C drive with all its programs etc would never be scanned. My question how do I permanently change the default drive to be scanned namely Drive C. I tried uninstalling ClamWin on the XP PC then re-installing to no avail.

Thank you in advance.
