Opera automatically downloads "f.txt"

  • Hi everybody,

    I'm new to this forum and hoping you can help me with the following problem:

    My Opera-browser automatically downloads a .txt-doument which is just called "f". It seems that this document is only downloaded when I'm using Opera and not any other application. It reoccurs periodically - but the longer I use Opera the more times it reoccurs. It started yesterday so right at this moment the eleventh document is downloaded ("f(10).txt). The problem first occured yesterday but continues even after an Opera-update.
    The document itself seems to contain sourcecode, but my knowledge regarding code is very limited. The first line (I will put that between "...") looks like that:"document.write('\x3cdiv class="GoogleActiveViewClass" ' "

    Thank your for any help you can provide! I really don't know what to do or what I've probably done to start this.

    Opera_version: Updated today to 42.0.2393.85

  • Hi, this is not related to Opera as such but to a countermeasure for a security issue in Flash. You can read more details about why this happens here:

    Try turning on Opera's ad-blocker (Preferences -> Block Ads), this might stop the files from appearing.

  • Hi avi,

    thank you for your help!
