Browser redirect to mc.yandec.com

• Nov 18, 2020 - 21:42

Hello,

I had the experience of completely uninstalling and then re-installing MuseScore 3.5.2 under Windows 10. On the second installation I found that when MuseScore opened, my system browser (Chromium Edge) would open to a URL at mc.yandex.com, which would never actually load. I determined this was related to the Start Center. Modifying my preferences so the Start Center didn't run at startup fixed it, and manually selecting the Start Center from the menu opened the browser.

Now the interesting part. I went ahead and did a complete uninstallation (including the folders under AppData in my user directory). Then I did another installation, but as I had in my very first installation, I opted to run the tours. Now no opening the system browser to mc.yandex.com. Then, after opting to stop seeing the tours, they were gone and the Start Center still didn't do the redirect.

So it appears the problem only occurs if I do an install and opt out of the tours during the initial program setup. Leaving the tours option on at this point, and then removing it later, works fine.

It's a minor issue, but I would assume it would be easy to fix as well.

I've never heard of this happening, can you provide more info? Like what URl, exactly? The start center normally opens a page http://connect2.musescore.com/, but this happens within the start center itself, not using your system browser. I guess if a firewall or some other setting gets in the way of this loading in the start center, maybe on some systems the system browser might somehow be invoked, but again, I've never heard of this happening, and there are literally millions of MuseScore on Windows. Anything unusual about your browser configuration?

mc.yandex.ru, btw, is an analytics site, it's referenced during the load of any page on this site (check this page's HTML source for example).

Ok, you will think I'm nuts, and perhaps I am, but I did the uninstall/reinstall dance again and I can't get the browser redirect to occur at all. The precise URL was:

https://mc.yandex.com/metrika/watch_match.html

Maybe some kind of spam attached to my system and has now been cleared by my antivirus. I swear this was happening every time the Start Center opened, either automatically when starting MuseScore or when invoking it from the File menu.

I knew from other posts in the forum about the "sub rosa" call to mc.yandex.ru for analytics, and that wasn't what was bothering me at all. The watch_match.html URL was opening either in a new browser window if there was no browser running, or a new tab if there was. Reboots or clearing out my task list didn't help, and I don't have a firewall or proxy, or odd network settings.

I'm going to chalk it up to some weird malware that got on my system, unrelated to MuseScore, and hijacked or piggy backed on the legitimate web calls made by the Start Center. Now it is gone.

Sorry to have bothered you. Great software, by the way.

No worries! I certainly believe you that it happened. That is a site referenced by the site loaded into the start center, so it can't be coincidence. But that shouldn't normally have resulted in your browser getting involved. Would be interesting to discover what that was in case it ever happens to anyone else so we can advise them better. Meanwhile, though, I'm glad it seems to have fixed itself for you!
