Oh could this be the sign of a serious issue or something? Everything seems to be working alright. I would screenshot it next time it autoupdates because I can't recreate it with the "Show Last Popup message" it just shows up as a regular update box. Also I don't know how to upload to the FTP thing.
Edit: This just started happening yesterday and it's not a huge issue to me, so unless you guys think something is seriously wrong I wouldn't worry about it. I'm looking right now and I can't even find the avast5.ini in that folder, maybe it's because I'm not using a clean install my install is back from when it called like Alwil Software or something. I've had Avast installed for ages.
