Not really, as the error message doesn't seem to have anything to do with what you were doing, e.g moving files to the chest, when the error seems to relate to updating.
You say "when I moved them to the virus chest" surely in the boot-time scan you would be moving them individually or are you saying you got this error at the same time, as this is an error from the log viewer and I don't know if during a boot-time scan anything is written to the warning section of the log viewer.
I get these all the time, how do I know this, only when I look in the logs to find something in relation to the forums. Me I keep my nose out of the log viewer as most of the information there is verbose and useful to the developers but not a user. Not to mention the message isn't what I would call a hard error, e.g. not displayed to the screen and I don't go looking in the logs unless I have a specific problem or errors are displayed to the screen.
So unless your are getting update failures displayed to the screen (red pop-up where the green update notification would be displayed) I wouldn't worry.
