hi

i have used anti-malware the last version on a friend of mine laptop ,running w8.1

well , antimalware find everything and did clean all of them

now my question :

 i have the original dvd (that came with the laptop ) , can i restore all the windows files to be sure they are not corrupeted ?

just use the dvd to restore them ?

or is there a way to use internet to check all of them

 

and if there is a way , can i use it with w7 and w10?
