"System Restore did not complete successfully, Your computer's files and settings were not changed.
Details;
System Restore could not access a file. This is probably because an anti-virus program is running on the computer . Temporally disable your antivirus program and retry System Restore.
An unspecified error occurred during System Restore, (0x80070005)"
I have turned off my Zone Alarm Extreme Security software, but I get exactly the same answer.
Unfortunately the message does not tell me which file(s) are causing the problem and the error message is so vague I can't try to resolve the issue.
