Quite silently the Redmond company released an optional update yesterday which disables autorun for USB sticks. This is one of the most dangerous entry points for malware currently used. Family members, friends or employees carry autorun Trojans around with them on USB gadgets and can infect other computers or networks that way. This is why with Avira AntiVir 10 our developers added blocking of autorun (in the Avira configuration with enabled expert options below “Guard”, “Search”, “Extra actions”) last year.
This is a step in the right direction. It will help keeping many computers clean in future. Unfortunately, as this update is optional, the users (and administrators) have to take action. By manually visiting the Windows Update website with the Internet Explorer, a custom search for updates has to be made and then the optional update has to be selected. It can be downloaded via the knowledgebase article from Microsoft, too. We recommend installing the update!
