My sons were on my computer and claim they didn't do anything but now my entire screen is extra large. I mean when I turn the computer on the Windows symbol and the cursor the start menu, everything is extra large. I don't have access to the control panel unless I am in safe mode and that is normal size. I have run my anti-virus in case they activated a virus and I can't do anything to fix it. I have tried to search from something and can't find any solutions. I also noticed that the number lock for the 10-key pad is off and I don't know how to activate that again.
Can someone please help?
