  • Hi I'm running Opera on Windows 10. sugr.swf automatically downloads at various times. I delete it often and right after it downloads again.

    What should I do?

  • Check your system for malware. Malwarebytes and ADWCleaner are good programs to try.

  • The following Sept 2015 posts appeared in the Apple forum, but they may also be relevant here to your Windows system:

    I've done a bit of research and I think (note that I think and I might be entirely wrong) that this is not malware but just a flash ad that doesn't trigger properly. VindicoSuite appears to be a legit ad network of some sort, and surprise: they have a product called Sugr. This makes me believe it is not actual malware but just a bad ad that doesn't behave as it should.

    As I suspected in my previous post, this is an ad gone bad. Not necessarily dangerous, but it's just not behaving the way it should. I had that ad show on my site yesterday and I contacted one ad network I work with who immediately disabled it. This ad is still going around other sites though, but again, I don't think there is much to worry about. Maybe avoid visiting these sites for a bit until they figure out the ad is bad and turn it off.

    In August 2015, a copy of sugr.swf was uploaded to VirusTotal, and only one of their 56 AV test suites identified it as anything. McAfee-GW-Edition flagged it as: BehavesLikeFlashExploit.dg ; all others reported the file to be clean.
