Emailing Virus

My mom recently opened a link from an unknown email address saying "wow this is pretty crazy you should look into it *link*" I know -.-
Now it is sending this to all of her contacts, I tried to mass reply to them but it won't let me. Is there anyway to combat this? I'm running a complete scan with quickheal now but I don't think anything will show up. Will this have any other adverse affects on my computer? E.g. Have a keylogger on my computer, etc. Is there anyway I can remove this virus if it's still on my computer?

 

First of all, change the password of the e-mail account on a safe computer.

Run hitmanpro, malwarebytes, combofix and superantispyware. Preferably all in safe mode.

I know it will take some time, but it's worth it to clean all your shit lol.
Malwarebytes will take the longest, up to 1,5 hours or abouts.
