Hallo, that 400.vps.bad file is a freshly downloaded new VPS which was checked and found corrupted.
This means that the VPS was downloaded but is probably unusable (using it would be security sirk, because its contents might be forged/malformed). Thus, it's labelled "bad", placed on desktop (for further analysdis what happened and/or what was actually downloaded) and the original vps (which was included in the installation package and was proven correct) is used instead as a fail-safe replacement. Try to push "check update" button and download it again.
Btw. please, send the 400.vps.bad file to me (cimbal@avast.com) for further analysis, what went wrong.
