Windows metro apps not working and Virus/Firefox!! HELP!

Today i just found out the some of the Windows metro apps are not working and when i try to start them up and it immediately closes and goes back to the start sceen.


And each time i reboot my Windows 8 tablet in the desktop opening up Firefox it keeps asking me to choose Firefox as your default browser and i keep saying yes but it keeps happening.


I think i have a virus on my Windows 8 tablet but my Anti Virus(Avast, Avira) did not find any viruses.




How do i fix this and the Firefox default browser thing???

Hello BillyTech95,

You probably has viruses in your PC and they prevent you to start metro apps and changes firefox to become your default browser.

Downloads Malwarebytes Anti-Malware Free and run a threat scan and deletes everything it found:

If the problem still persists, downloads AdwCeaner and run a scan:

Run a scan with SUPERAntiSpyware if AdwCleaner and MBAM doesn't solve your problem:

If your problem still persists, I would recommend you to reset your Windows 8 PC.

Cheer!

You can also use System Restore to restore back to the time before you start having problems.

Ok i downloaded the Malwarebytes and other software you suggested. and it scanned and at the end it did not find any viruses or anything like that and it actually made ALL of my Windows (even the default)metro apps stop working and immediately closes and goes back to the start sceen Now i can't use the video player Windows Metro app because of this!!

And every time i boot up and open Firefox it keeps asking me to choose Firefox as your default browser and i keep saying yes but it keeps happening.

And sometimes when i boot up my Windows 8 tablets there is a cursor in the of the sceen and before the User login sceen it goes away and i have not have my USB mouse plugged when i see it.


And it is becoming slower everyday opening firefox and other apps are not loading not as fast anymore and when i do a task it lags for about 2 seconds and it proceeds to do the task, it is annoying sometimes especailly when i do some video editing/making Youtube videos.. :/


What should i do?? Should i factory reset my Windows 8 tablet again or not?? I don't really want to do that again....

I really don't know what to do..... :/ :/

Hello,
Have you try system restore to restore to the time when you haven't encounter this problem?
Try open task manager and see if there are unknown process running. You can reset your PC if you still cannot get this to solved. (Backup important files first before reset!)
