It appears that AV detection is becoming more aggressive and obstinate. I use Norton Security, and the latest activator gets quarantined despite my having explicitly excluded the executable. Attempts to restore it from quarantine simply get ignored - no error message - just no action. I found it necessary to exclude the triggering signature in order to eliminate further detection. In my case, the threat signature is "SONAR.Heur.SBG1!gen4"; it'll probably be named something different in other AV suites.
I just saw that for the last 9 days True Image had not been making automatic backups anymore. Even when I manually click the button to Backup Now, it just immediately says backup successful but nothing actually happens. I guess it is because there was a new version available. I've now updated to the latest version, 10410, and the backup is working again. @nova-s Is it expected that each time a new version is available from Acronis, the existing installed version will just stop working? Luckily nothing bad happened to my system in the last 9 days, because I didn't even know that my backups weren't running in the background.
