Recently my computer & my UMPC has infected by viruses. I'm using windows XP sp2. I can not view my hidden files. The "Folder Options" still can be viewed, but the "view files" setting has set to "Do not show hidden files and folders". When I set it into "Show hidden files and folders" and click OK/Apply....it doesn't work. It seems like my registery setting has modified by a virus. And
I remember that day my friend has inserted a flash disk to copy some files. And it infected by a virus.I will tell you this virus threat & behaviour in my another post because in this post I just want to tell you about preventing virus infect from flash / USB disk or external hardisk & memory. Usually this virus spread by infect the flash / USB disk and planting "a virus egg" which automatically breed the virus when flash /USB disk inserted in a computer PC or Notebook.
- Autorun.inf (this file is command for autoplay windows to execute any file and the file can be a Virus Script or executable files)
- VBS visual basic script which can be a virus script
- exe file which can be an executable virus e.g : ctfmon.exe
Those files usually set into hidden files.
To prevent this kind of Virus I'm using NINJA PENDISK!. This software is a freeware, small, but usefull. I found it at the internet at http://nunobrito.eu/ninja/ . Ninja pendisk can protect the autorun virus by detecting and deleting "virus egg". It can be laod at start up so it run in a windows system tray. So when you insert a USB / flash disk it will work immediatelly by detecting a suspicious autorun and autoplay behaviour.
This software only work for detecting autorun virus (virus egg) but not for trojan, macro, polymorphic, boot virus, etc. So you must have any powerfull virus protection. But you know even I'm using a powerfull anti-virus I must double-protect my system because there are alot of ways for a Virus Maker to make confuse and desperate someone elses and he/she will laugh above misery..:))
