Please see the picture. (folder names are deleted by me)
OK, yesterday there were those 3 shortcuts in top, 3 directories, and 'notepad, calculator, ms paint', I use all of those everyday, so it's not mistaken.
And today I suddenly discovered that calculator and ms paint shortcuts are gone.
So I checked the directory, and- (as you can see in the picture)
1.calculator shortcut is still there, but hidden in the start menu.
2.ms paint shortcut is removed.
So I googled for information and did what I could, I ran unhide.exe, anti-virus(avast), and anti-malware(malwarebyte), and I think my pc is clean, no virus or malware deteced. and calculator shortcut is still not showing.
I'm afraid if it's a sign of some remote manipulation from some trojan or someone.
How can I solve this?
