I wanted to chime in, I'm receiving a similar error. Upon logging in, I get 5 identical code 10 error windows that all pop up. Then, usually if I jump right into Safari, I get a few more. Only an annoyance, except that this probably means at least some of my (corporate) Symantec 10.2.1 AV isn't operating.
A bit disappointing, because if they can't handle an OS update that's been in the news for nearly a year, then how can they handle viruses? And isn't it a big breach of security to have the software not working, or even if it is to have it generating errors that may make users uneasy? Uneasy users uninstall, or fiddle trying to fix things, etc.
I'm going to try to follow this topic to see if any resolution is posted soon. In the meantime, I'm going to pressure my organization to consider buying an alternative AV package. Try to hit Peter Norton where it hurts, in the wallet!
