    Can this harm my computer?

    No, this will not harm your computer in any way. This will only freeze or lag your computer, but after rebooting, it will be completely fine.

  • Question
    Will this cause my computer to crash?
    Hello903hello
    Community Answer
    No. Unless your computer has too little RAM (Random Access Memory), or you opened up too many apps (especially Google Chrome). In that case your RAM would be used up and cause your computer to lag.

      Tips

      • You can change the filename from virus to anything you want, just as long as you change every part of the file where it says virus to your new name.
        Thanks
      • When changing the name, be sure to keep the ".bat" part.
        Thanks
      • To change the icon of any short cut, right-click on it and select properties. Next, click the change icon. It might give you an error but ignore it and continue. Then select the one you want, and press okay/apply.
        Thanks
