Hi, something is stopping my AVG from opening at all. I recently upgraded to Windows 10 but didn't like it so reverted back to Windows 7, but ever since then my AVG will not open. I have tried downloading again but just keep getting the following problem: Requested file not available on server. (Severity: Error. Error code: 0xE0018D32. Error Message: Requested file is not available on server. Addition Message: Failed to download files. Context: Initialization of the AVG online installer.) I have scanned with Windows defender and MalwareBytesAntiMalware but they didn't find anything. Can anyone suggest what I should try next as I hate being without antivirus protection abd don't trust Defender to do an adequate job. Thanks

I am using the AVG 2015 Free program (or at least trying to),
