I amrunning Win7 Ultimate. When I try to do a Systm Restore, it seems to run to completion, reboots the system and then issues the following message: "System Restore did not complete successfully. Your computer's system files and settings were not changed. System Restore could not access a file. This is probably because an anti-virus program is running on the computer. Temporarily disable your antivirus program and retry System Restore. An unspecified error occurred during System Restore: (0X80070005)" When I disable my Norton antiVirus program and retry, the same thing happens. I would appreciate any advice as to where I should start looking for a solution to this problem. Thanks.
