Need help with destroying a virus¿

Malware Bytes might help, if I'm not mistaken.

Try ESET NOD32 trial and Malware Bytes.

What do you mean when you say that she can't delete it? Is she unable to do it, or is it one of those damned autoregenerative viruses? Anyway, try with an updated antivirus, some malware removal software (Above me two guys recommended Malware Byes), or delete the infected files using Linux.

KILL IT FIRE!!

Internet security is the "better safe than sorry" real deal. Avoid virus and such may be a little hassle but getting them out when they're already kicked the door... Oh man, what a battle...

Have you seen this? Did you tried already? Hope it works.
