AVG detects Opera update as virus

  • Hello all,

    I recently installed Opera in my Windows 8.1 laptop from the official site "". Today, after a month or so, I received a warning from AVG antivirus about a threat detection concerning Opera auto update. More specific it concerned the file:

    c:\windows\temp\opera installer\installer.exe

    and in the details of the report there are more files like:


    Moreover, I would like to mention that according to the creation date-time of the above folders and files, there are very close to the date-time of the Opera 42.0.2393.137 update.

    I would appreciate if anyone could answer my questions:

    • Are these files legit and part of the Opera update process?
    • Are you aware of any similar reports from any antivirus SW?
    • Is there any additional measures that I must take?

    Thank you

  • What was the actual warning? Sometimes they are set to warn on things that act like a virus rather than being an actual known virus, these sort of "heuristic" warnings can be false positives.
