If you receive the "Invalid update control CTF file" message during AVG update (on the station) or "Failed downloading file '/avginfowin.ctf' (avginfoavi.ctf) (error code 0xE0018D0A) (in the AVG Admin Console), most probably the update control files are corrupted. In this case it is necessary to delete these files manually. During a next attempt to update AVG, new control files should be downloaded and update process should be completed without any difficulties. Please kindly follow these steps to delete mentioned control files:
- Navigate to the folder where the updates are stored (C:\Documents and Settings\All Users\Application Data\avg8\Admin Server Data\update by default)
- Find the avginfowin.ctf and avginfoavi.ctf files
- Delete these two files
- Please restart the AVG Admin Server
