Cn911.exe
As of late a virus by the name of cn911.exe has spread itself amongst usb flash devices on the majority f st. columbs computers.
I have since( I hope) developed a method to halt its spread. Important to note that this not cure the virus but rather prevents you posseing it. If you fear your home computer is affected by the virus then i suggest downloading anti-virus prtection. Computeractive regard AVG highly and therefore i recommend it as i now it cures the virus and furthermore its FREE! (download link: http://www.computeractive.co.uk/vnunet/downloads/2129071/avg-antivirus-free-edition)
I've tried this amongst my usb sticks and so far so good. Note this will only work if not affected by the virus on the memory key. To ensure this format your usb memory key (ensuring files are backed up else-where) and begin at step 2.
1. Ensure your windows can see hidden files and folders, and extensions.
To do so My Computer>Tools>Folder Options>View tab>Under Advanced Settings check “Show hidden files and folders” & Hide protected operating system files is unchecked; hit apply and ok.
2. Make a Notepad file, leaving it blank saving the file as Cn911.exe (to do so slecet to save as all files so its not cn911.exe.txt which is the normal save settings)
3. repaet only this time design one under the name of Autorun.inf
4.Now right clcik on each file, select properties and at the bottom ensure read-only setting is checked.
5. Now make sure both these files are located on your memory key.
6. This should work however if any difficuilties are experienced reply to this post.
Dont worry if these files dissapear on your memory key later, thsi means the virus has re-attempted to attack your memory key and in doing so has made both the files hideen. Dont worry however it was unable to modify the files because of their read-only feature.
That reminds me make sure that hidden files is unchecked on yoru computer again so you dont delet any important system files.
If i feel like it this post may be updated with screenshots and more in-depth explanatiosna nd instructions.
