I have been using Windows 8.1 on a brand new computer for about a month. Since yesterday, about every half hour or so, a web page pops up saying:

=======================

Message from webpage

Microsoft Real Time Web Monitor has detected Liam.x on the system Due to Unsafe Browsing.

Its (sic) strongly adviced (sic!) to contact Windows Online Support to have the virus removed as it can cause a system failure.

Please Call Microsoft Windows Support Helpline for Assistance.

=======================

Win 8.1 inbuilt Defender program doesn't detect this virus (even after a full scan). Nor does Malwarebytes.

Is there a recommended way of removing this virus? I just did a System Restore to about two weeks ago but the virus is still there.

1. This is phone scam. Never ever call these numbers. Never provide credit card numbers when they want you to do so.

2. If you receive something like this and if you like to be sure, then you can backup data and restore clean installation from reliable backup and restore data afre restore clean install. (You have good backukup I hope.)

3. If you feel like IT expert, then you can do analysis to find which process(es) is(are) causing troubles (with Sysinternals tools), dig into these processes, kill them and remove.

4. Never use more AV at the same time, unless you are certain that these are not interfering with each other. Keep AV database up to date.

5. Be very cautious about where you "travel" on internet. Clean IE cache, search what has Internet added, never save password,... Use special computer for dangerous experiments if you are doing something like this and avoid doing this on computer that host important data (workor personal).

I downloaded a couple of free games from the inbuilt Windows 8.1 Microsoft Store. I didn't download any software whatsoever from any other site. Nor did I browse any unsafe web sites.

Anyway, I'm now back on Windows 7 and happy again.

Thanks everyone for your responses. I imagine other people out there must also have experienced this problem.

Same issue here. Also using Magic Puzzles.

No AV solution or Malwarebytes detects it.

MS - this is YOUR app store - people purchase items though it, via your secure system which means it is down to you to fix the infected applications.

Sort this out!

Was a conclusion reached?

I have just installed Windows 10 in place of my virus free Windows 7 Pro. It includes the Microsoft Store so I presume I can once more download Magic Jigsaw Puzzles.

If I do so, will I also download the virus again?
