Trojan horse small bog

I had this issue today on a customer’s computer.

In late July 2009, there was an issue for users of AVG Anti-virus and iTunes. AVG, one of the most popular anti-virus programs, caused confusion by wrongly identifying iTunes files as Trojans. After updating its virus definitions, the anti-virus software finds up to 181 “viruses” in iTunes: attempting to quarantine the files prevents iTunes from working. The supposed virus name is “trojan horse small.bog”.

Symptom:
You try to open iTunes and get an AVG Alert telling you that iTunes.dll and iTunesRegistry.dll are infected with “Trojan horse Small.BOG”.

Cause:
AVG was giving a false positive: there was no actual Trojan in iTunes. AVG could have quarantined the files, that will break your iTunes install.

Fix:
The problem with AVG was quickly resolved with an automatic update. If you encounter the symptom:
Open AVG and click “Update Now”, then re-install iTunes. Your music files will still be there.
