Can't delete .dmg from hard drive
When scanning with Sophos anti-virus, this LG bd670 manual.dmg pops up as the only 'threat" to my computer.
I tried to clean up with Sophos, but it failed, then tried to delete from the finder, and got "The operation can’t be completed because backup items can’t be modified."
Running 10.10.4 (14E46), but had the same problem with Mavericks.
Suggestions?
Mac Pro, OS X Yosemite (10.10.4), 5,1
