    Hi Support,

     

    This seems that the Definition uploaded on Symantec portals are corrupted for both 32 & 64 bit and even the clients are requesting for Full.zip Please check the snapshot and suggest for any solution...

    Same here, IE is complaining invalid or corrupt signature. But no problem with Firefox.

    I'm sure that this is a MS issue. AFAIK, Symantec updater files are signed with SHA-1 signatures. But SHA-1 slowly gets obsolete. It seems to be that IE and Windows are handling SHA-1 signatures differently. While Windows is showing a valid certificate (see under "properties" of the file), IE does not accept it because it's following Microsoft's policy to abandon applications that were SHA-1 signed since the beginning of 2016.

    For more info, see this site:

    If you want to be on the safe side, you can check the definitions against the MD5 hash Symantec is providing on the download site.

    All in all, it's a cosmetical issue. No corruption. That your clients are requesting full.zip files must have another reason.

    There is not any issue from Symantec end, as stated above it could be browser & environment specific issue.
