How to protect the PCs from the driveby spam
In order to protect the PCs from the malware, users need to make sure that their email account is protected against spam and malware and that all spam and malware filters are duly updated.
Displaying HTML emails in the users' email client should be deactivated and they need to go for the option of displaying emails in pure-text format only. That way, users can make sure that the HTML content is contained in an email attachment and the PC will be infected only if the attachment is opened.
