Virus Definition’s Don’t Always Protect You, Take Precaution

Recently, I received a call from a client, they were infected with a virus. This virus had modified the network share and hide folders. It then created folders that where executable. This client had current virus definitions, but it was a new variant of an existing virus. How could have this been prevented? This virus spread with USB drives and also with email attachments. All email attachments need to run through a virus scanner and emails with zip or exe attachments really should be blocked. With file sharing sites, it is an easier way to share files. Also USB drives should be limited in use. Unless someone has a need to move files around, USB drives should really be restricted and blocked.
