A virus in the CF card


I have read at various places that computer viruses do not infect memory cards....well that is not entirely true. Yesterday, at a friends place I plugged in a CF card that he had got from his friend and found a USB type autorun virus that i blogged about previously under the Nhatquanglan name.
As I connected the CF card to my laptop, the free AVG antivirus lit up and healed the infection too, I wonedr might have happened if the CF card was put into his canon 400D SLR. It seems that if a CF card is used like a pen drive or a flash drive to transfer data (pictures even) from one infected computer, it can be infected with this type of virus. What it does when plugged into a camera is something I dont know and dont want to find out. To all those reading this, do not use your CF cards as pen drives, use them to store pictures in the camera. keep your computer clean with any antivirus...burn pictures on to a CD, use the CD to get pictures printed from the shop (if you dont have your own printer).

USB VIRUSES!!!


Lately there has been a rash of virus attacks in computers around the area. It all started with a friend telling me of something strange going on with his computer. Namely, whenever he tried to open orkut.com, there was a devilish laugh and a window that had a fairly uncomplimentary message. The long and short of it being that opening orkut.com was impossible. The second being another similar window that prevented Mozilla Firefox browser from opening, and thats not all because after advising the user to switch to internet explorer, IE would shut down after a few seconds too. The third virus in the zoo was something called Nhatquanglan (someone in HO Chi Minh city Vietnam). This guy was pretty cool too, it would reproduce itself every time a folder is opened and take up some space. More irritating was the fact that it would disable the task manager and the folder options (ostensibly to prevent the user from shutting of the program). They were apparently being spread by flash drives, and no anti virus program seemed to be able to do anything about it. This necessitated a fairly radical operation in which some software like Hijack This, and reanimator had to be downloaded to clean the laptop up. So far it seems to be holding up. But what I am looking for now is some sort of a vaccine for a USB drive. Giving its overwhelming convenience and yet stupid safety profile, I hope someone somewhere , smarter than us all would get around to doing something about this.
That person would earn my undying gratitude.

On the other hand, I hope good sense prevails and life goes on smoothly.
