Did you checked after executing the command chkdsk /f and after restarting the pc did the Chkdsk command ran and found any errors?
Today all of a sudden, I am facing this problem. Whenever I'm running Google Chrome (which is my default browser) or just logged on to my laptop, I am getting this pop-ups that show this message .
Initially, I thought it may due to some virus or something, so I scanned my computer with McAfee Enterprise. Then scanned with Malwarebytes to look for malwares. In both cases, no infection/virus was found. I also uninstalled Chrome & then reinstalled, but that still did not work.
So, I opted-out for the last resort, I went back to a previous restore point from last year so that there would be no problem whatsoever. Now after that, I still get these pop-up messages. While typing this question, I've received the pop-up more than 5 times. Just to mention, I've tried to resolve the issue from Microsoft (http://support.microsoft.com/kb/176646)
That did not work either.
So, PLEASE anyone help me out what this issue is & how should I resolve the problem.
PS - I've tried what the pop-up showed as the very first solution. Then I opted-out for the other help.
