With the recent massive global cyber attack, there is a nice simple fix to stop this in its tracks
By creating a read-only file - named perfc - and placing it within a computer's "C:\Windows" folder, the attack will be stopped in its tracks.
I read about first on the BBC Website, you can also read about it in more detail here on Bleeping Computer.
I am always interested in your thoughts so if you have any comments or feedback then please feel free to add any comments, or you can mail me here.
