Do you have a flash drive and access to another computer to download malwarebytes and stuff on it then install it on the infected machine?
At times, i have sent people malwarebytes via instant messenger and/or email (if not using a web based client).
Also a complex way is to have someone put the file on a ftp site and use the command prompt ftp to download it, this method is complex if you never used FTP like this.
EDIT: Oh, sometimes a direct link will bypass virus roadblocks. Do not click this link, however right click on it and copy link location THEN paste it directly into browser (I guess you can try clicking on it first)http://software-files-l.cnet.com/s/softwar...-setup-1.46.exe
