You never had the same issue to begin with!!
You didn't read the issue correctly from other users in the forum and assumed it fixed your issue.
The issue has ALWAYS been that Av update files. NOTHING ELSE
There was NEVER and update error. There no such thing as an "update error" in ZA to even begin with.
The avupdate would fail and that is the only update issue that ever happened to others just recently that we fixed in the software.
For you its a PC related issue and NOT ZA. If you have another PC on the same Internet connection with ZA installed and doe snot have any AV UPDATE ISSUE ONLY!!!
