I just installed v. 2.0, and everything went off without a hitch, EXCEPT that when I do a scan, I get the following message: "Error occurred while scanning MBR sector of the .1 physical disk. Error reading sector." I never had that problem with v. 1.x. However, I ran CHKDISK to see if the problem was with my hard drive, and found nothing. Have noticed no other effects to indicate that the drive itself is damaged. Could this be a bug with v. 2.0? I am a devoted fan of NOD32, and in no way mean to complain.
