avast has been very hot on these injected iframes and of all the detections I have checked out on the forums all have been good detections. Even did a passenger list search and no alerts.
Like CharleyO I didn't get any alert so if you can provide the full URL, see below.
Check the avast! Log Viewer (right click the avast 'a' icon), Warning section, this contains information on all avast detections. C:\Program Files\Alwil Software\Avast4\ashLogV.exe
- Or check the source file using notepad C:\Program Files\Alwil Software\Avast4\DATA\log\Warning.log
