Disabling Auto Startup

  • I have the same problem. Opera starts at boot with previous tabs AND adds 3 Speed Dial tabs. I tried everything listed but no go. Even did a search on "opera" in the registry. Everything looks fine. No malware. No viruses.

    Version 50.0.2762.67 (PGO)
    Windows 10 64-bit

  • @sandy-shores Check the 'startup' tab in Windows task manager, maybe something there is triggering Opera to open on system start up.

    If you close all Opera tabs before shutting down the system, on the next startup does Opera starts with any tab opened other than the Speed Dial?

  • @sandy-shores

    If nothing with Task Manager, try with SystemExplorer.

  • @ogmtxvr It could be an issue totally NOT related to the browser!
    I have the same issue with Chrome, Vivaldi, and Spotify. When I restart Win10 one of the mentioned software start automatically.
    I discovered that some software on my computer (I never understood what, I reported on Microsoft support forum but I had no help) creates a strange file named as the current user (in my case 'Kevin') in C:\Users that auto start when Windows starts (see images)

    Deleting the file will fix your issue until another software change will trigger this behaviour again.

    Here you can see the file in Task Manager (right click on it and choose 'View in folder' to find the file):

    Although it is mentioned twice, the file is only one. Deleting the file will fix your issue until another software change will trigger this behaviour again.

    NOTE: I use Advanced SystemCare (11) to keep my Windows in order (registry defrag, junk cleanup, etc..). Maybe this has messed up Windows, not sure though. It's just the only thing I can think.

  • @pandorave

    Have you checked the file description to find out info related to the program?

  • @zalex108 Yes, it seems to be a generic file, not even having an extension


    The content is this:


    This is the first time I see this in Chinese (I suppose it's Chinese). Usually, it was in English and was like a system file. I'll delete it and try to replicate the issue, maybe it regenerate in English next time.


    Btw, I see now that the file has been created on the 17 January. In that date I've installed Open VPN and probably Microsoft OneDrive has updated (see image below)


  • @pandorave

    Check it on the next Reset/Format to know which one is the responsible.

    Sorry, I don't understand 😶
    What are you suggesting to do?

  • @pandorave
    That looks extremely like malware to me!
    Do a scan with malwarebytes and hijackthis.
    If there's anything there, one or both of them will surely find it.

  • @davehawley Thanks, I'd actually started a scan some hours ago (using Avira free). I'll post the results when finished.

    Scan completed, nothing relevant but some files in a zip folder. Removed them anyway.

  • @pandorave
    Well that's good news, but what you described earlier with files with Chinese content mysteriously appearing in critical parts of your system certainly looks like something nasty!
    I would still have a go with malwarebytes and hijackthis.

  • I don't know if adwcleaner is included in malwarebytes since malwarebytes bought it, but running the separate adwcleaner in addition might help too.

    Advanced SystemCare

    VirusTotal scan on advanced-systemcare-setup.exe for Advanced SystemCare 11..
    Note : Setupfile from IObit webpage..


  • @zalex108 Nothing there. But thanks anyway.

  • @leocg Interesting things happened. Closed all tabs individually as you suggested. On next startup Opera did NOT start up. I manually started it. Only tab was Speed dial. I opened another tab (Twitter) and closed Opera. On the next startup Opera did auto start. First tab was this page of the forums, second tab was Twitter, then three Speed Dial tabs. I have Opera set up to start with previous pages so not sure how this page came up.

    I appreciate and have tried all suggestions under this topic. I used Opera when it first came out and I don't remember why I abandoned it.

  • @sandy-shores

    And is every entry familiar?

    Maybe, you are looking for Opera but it's another program opening an URL's.

    You can check the Tasks Scheduled - from SystemExplorer itself -.

    If you need, you can upload a screenshoot.

  • @sandy-shores

    The new comment seems unrelated to a startup entry.

    You may need to back up your extensions and its settings and use a clean profile... if fixed you can start over or check disabling extensions, cleaning cache... etc.

  • Well whether @pandorave and @sandy-shores problems have the same cause or not, fundamentally no browser should ever start itself up automatically when the system boots up.
    I can't imagine any reason why that would happen other than through the action of some malware.

  • @davehawley @zalex108 @burnout426 @nvmjustagirl and anyone else I may have missed. This installation of Opera was "fresh out of the box" (downloaded.) I have never had Opera on this machine. So I used Revo Uninstaller to uninstall it, scanned registry and files for opera, ran virus and malware scans and reread all the posts for anything I may have missed. Did plenty of reboots in between to make sure my system was okay. All is fine without Opera.

    I tried a clean download and install of Opera. Same problem. I copied the install program to a flash drive and installed it on a W10 (not upgraded from W7 or W8) laptop and it works fine.

    I am running a desktop upgraded from W8 to W8.1 to W10. I have noticed that some programs will act funky at first but I can usually figure out the problem. The same programs run great on the W10 laptop.

    I am probably due for a clean install of W10 - and only W10. Until I get that done I am going to put the one website I need Opera for on the Speed Dial tab and install the one extension that Opera has and FF no longer supports. But some good has come of this. I found out about Hekasoft Backup to replace MozBU that is no longer supported for FF.

    Thanks for all your efforts. If I have the same problem down the line after the W10 install I'll check back to see if this thread is still here or I'll start a new one.
