I'm trying to remove a malware program for my mother's computer called antivirus soft. Nearly every webpage I found explaining how to remove it says the same thing but it has not helped. I have tried running Malwarebytes and it found one file that was deemed malicious, but that did not remove antivirus soft. I tried to do an update on Malwarebytes but I get an error message when I try to do that. I then downloaded a program called Security 360 by IOBits which found 25 threats but they were all cookies. Removing those did not help either. Can anyone suggest what else to do at this point?
