I am using HP Compaq nx 6120 notebook with Win XP Pro SP2. I’m using AVG free 7.1.385 antivirus which I update regularly. Of late I’m getting the following error when I do a full system scan ‘Partition Table(MBR) – Reading error’. The boot sector of the disk is ok on the scan. I don’t have any partitions on my hard drive. It’s only C drive that is present. I contacted AVG & was advised to delete all temporary files, run the scan disk utility & scan again. I followed the instructions but the same error appears again. AVG says that it’s a system error & not a problem with their antivirus. Please advise.
