AVG Sparks False iTunes Trojan Horse Alert
AVG, one of the most popular anti-virus programs, is causing confusion today 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”.
An extensive thread in the Apple discussion forums shows that AVG is giving a false positive: there’s no risk of trojans in iTunes, and quarantining the files will break your iTunes install. You can disable the alerts by creating an exception in AVG:
1. Open AVG
2. Go to Resident Shield -> Manage Exceptions -> Add Path
3. Add C:\Program Files\iTunes and C:\Program Files\iPod
AVG will no doubt correct the issue in their next definitions update.
