Hi Guys,
It was a bit late last night an the missis was moaning!
Here is a bit more detail regarding the 'missing .bin file AVG problem fix.
I did an uninstall and then a fresh install of AVG free 8.0.138. To my surprise I found it still had the missing .bin file issue when I did the first auto update.
So I went back to Grisoft to do the updates manually, you download the file to a convenient place on your harddisk and do a 'tools/update from file' in the AVG top menu bar. I found the first update 'Windows 8.0.164' was fine. Tried an auto update again and it still gave the missing .Bin file report. I think I noticed in the update dialogue it was missing a 1616 bin file. Tried the IAVI:/1616 bin file download from Grisoft.com and it didn't work. So I went to the UK Web site:
http://www.grisoft.com/uk.download-update
The download and 'update from file' worked fine and AVG free is now fully operational, no reported errors with the auto update dialogue.
Must have been a coincidence with the trojan attack?
Still alls working now.
Best regards
Dave
