Program Files/Grisoft/AVG Free/Update
My PC has been grey for a couple of weeks now due a recent update from Grisoft (stalled since last ver 7.0.323). Thanks DErifter for giving the base to this idea. The following has resolved the problem and things look back to normal now.
I have no "Update" file in my "AVGFree version 7" directory although, I recall, this was a feature on v.6 - follow the following steps for v.7:
Modified procedure from CastleCops ...
If you need to perform a manual update first you will need to get the latest update files from the AVG Free website at the AVG Free Update Files
Download the "Priority update" files to a directory on your computer that you can find later (Note the "Recommended update - u7f33861.bin" has no effect, so don't bother with it). You must remember where the directory is because you will have to tell AVG where to find these files later. I created an "Update" folder in the Grisoft/AVG Free folder thus: Program Files/Grisoft/AVG Free/Update.
After you have the files,
1. Verify and update your computer's time and date, AVG uses this info to determine if you have the correct files.
2. Open the Control Center,
3. Double Click on the Update Manager or select it then press the Properties button at the bottom of the screen.
4. On the Properties screen unselect the option labeled "Do not ask for the update source", click Apply and Ok.
5. Now click the Update button on the bottom of the screen.
6. In the pop-up window, click the Folder button.
7. Navigate to the folder where you had downloaded the update files into and click Ok.
8. AVG will update now with the file you had selected unless it contains the same as you already had.
That should be all you need to have updated your system, the AVG icon is now coloured and the XP alarms have dissappeared.
I've reset my Update Manager to "Do not ask for the update source" and hopefully, the next auto-update should work fine.
