However, what should I do with the AVG (above error) in the Add/Program section.

avg updating virus definitions failed-31

I want to know where and how I can use them to update the second computer. If I am right, you should be able to share your - C:\Program Data\avg10\update folder with your second computer.

I have yet to test this option, but it looks like it should do the trick for you.

To download incremental/full updates for engine definitions, you must allow Meta Defender Core to communicate with the servers listed below.

Depending on the scan engines you are using, you may include a subset of the servers.

After I downloaded the AVG files (saved to desktop), there are 2 files on the desktop:1) avg_free_stf_en_8_138a1332 (application file) 2) avg_free_stf_en_8_138a1332(PART File)Normally the installation launches when I double click it. According to below, I should have been more cautious. you for everyone's advice. I still get 2 files when I download from the AVG website (via CNET's).

Even when I tried to download AVAST, I still got 2 files. I don't think I can restore AVG back to when I had version 7.5 though. You would have to go FAR back to get to your "old" AVG 7.5 .......In order to manually add updates to your AVG Antivirus, you must save the installer to your computer, then access the Options menu and use the 'Update from folder' option to select the BIN file.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.The following table describes the servers which Meta Defender Core connects to for each corresponding scan engine.Some scan engines have two URLs because Meta Defender Core initially connects to and then redirects to its final destination.To ensure your AVG Antivirus provides full protection at all times, the AVG team analyzes new threats and information regarding new viruses, releasing updated virus definitions and antivirus improvements periodically.
