A database update from AVG over the weekend left users with crippled iTunes installations. According to numerous online reports, the update – which came out on Friday – appears to be mistaking iTunes.dll and iTunesRegistry.dll for a Trojan horse identified as Small.BOG, and thus consigning these files into quarantine. As a result, iTunes will not run, and is not fixable by a reinstall.

Another fine reason to avoid using AVG, although it could happen with any A/V software I suppose

AVG is a great program. And its not just the free versions affected, my Pro version did the same thing. I noted what files were being noted and selected 'ignore'. Crazy...I know.

Considering the multiple times I have seen Itunes software put a "gag" on a PC's CD/DVD drive that could only be corrected by un-installing Itunes, this seems appropriate. Apple wants control over any machine its software is installed on. Go AVG!

Yeah I saw someone complaining about this on another forum I use, I told them to add the iTunes files as exceptions so that AVG would leave iTunes alone. And yes it wasn't just the free versions that were affected, the user was using the Pro version.

But then the person got an update from AVG within a few hours that fixed the issue. I mean yeah it would of been an annoyance if it affected you, but the timely manor in which AVG corrected the issue was good I think.

I have used AVG for some time now, all this while the free edition has been fine but i have found problems in the past related with iTunes and AVG. Perhaps we should migrate to a different antivirus such as McAffee? Nope.

Or you could stop using iTunes.
