I do have a few 1.7.10 mods when I'm trying to launch 1.8.9, but For some reason I can't delete it or move it. A message keeps appearing on the screen saying :

____________________________________________________________________

This file can't be moved [or deleted] because it is open in Java SE binary . . .

Try Again Cancel

____________________________________________________________________

Even when I have nothing launched on my screen! Is there a virus or something?

open your task manager (ctrl-alt-del) and shut down every process named 'java.exe' or 'javaw,exe', then try again. rebooting should also do the job.

and yes, it might be a virus, as some sites such as minecraft-mods.com are known to spread malware. only download mods from curse, curseforge, github or the developer's homepage!
