My computer has a virus on it and I can't boot up Safe Mode

Yes, I meant to write it that bad.

Step 1. Secure the files you can not lose. You didn't call out the name of the virus so the usual advice is to scan with the list by Grif which is Step 2. Do not proceed to step 2 without completing step 1.

Why? Some virus (which we can debate if malware is a virus later) are booby trapped so when you go to remove them they could encrypt your files and demand payment. SAVE YOUR FILES ON BACKUPS FIRST.

Here's the list by Grif: http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3

In order to use the tradition F8 Safe Mode access, try using the instructions below:

If you’ve still got access to the desktop, enable the old Windows 7 boot menu options screen, (which allows you to access the “Safe Mode” options by pressing the F8 key immediately after startup), by opening a command window with admin privileges (If you're unable to use the "Search" window to open an elevated Command prompt, RIGHT click on the Start button, choose "File Explorer" and drill down to C:\Windows\System32\cmd.exe. Once there, RIGHT click on cmd.exe, choose "Run as Administrator"), then type the text below and restart the computer twice, using the F8 key the second time to access Safe Mode.:

To enable the older boot menu screen:
bcdedit /set "{current}" bootmenupolicy legacy

To revert back to the original Win10 boot menu :
bcdedit /set {default} bootmenupolicy standard

Hope this helps.

It seems as though the Windows 10 "upgrade" process may not install all the files correctly, or maybe they're damaged, or maybe something else, but running Chkdsk has fixed quite a few of these minor glitches. Try running Chkdsk in "repair" mode to find any damaged files and correct them. Start by opening a command prompt as an admin. RIGHT click on the Start button, choose "Command Prompt (Admin). (Or type "Command" in the search line, then RIGHT click on the "Command Prompt" listing at the top, choose "Run as admin".) Once there, type chkdsk /f /r /x, leaving the appropriate spaces between the letters as shown, then press the Enter key. You should see a note that it can't be run till a restart is done, type "Y" for yes, then press the Enter key again. Close the command prompt and restart the computer. Chkdsk will run upon restart and will take quite a while to finish.. Don't panic when the progress bar stays at 10% for a long time. It's fairly normal and the Chkdsk process may take a couple of hours.

When it's finished, it will boot to your normal startup/lock screen and you can login normally and then see if things are working correctly again.

Hope this helps.
