My son has come home for the Christmas holidays and has been using the computer. This morning he comes out to my radio shack all of a panic saying there's a virus on the computer. He said everytime he clicks on Firefox to access the internet it comes up with a program that starts checking all the disks on the machine and when it's complete it says it found various viruses on the disks. It turns out it's a browser redirect and once it's opened you can't close it, it is a very clever web site because it looks just like a Windows desktop and anyone who uses Windows would be easily fooled into clicking on the links. It did want me to download an exe file as well, thankfully that won't work on Linux.
I just deleted the .mozilla folder and normal service was resumed when Firfox was restarted.
He had been watching a lot of YouTube videos, so I expect there was some malicious site on there he picked that up from.
Yes and no, I do actually feel sorry for Windows users receiving something like that, it must be pretty scary. It does also highlight the fact that the applications in Linux are still vulnerable to attack, so don't get complacent, even though the attack is much easier to deal with.
Thanks for you kind wishes, all the best for the coming new year to you as well matey.
The point is though, it's ineffective. It can report all it likes, but it's got nowhere to go and it's a good practical demonstration of why (at present), it's not really necessary to have anti-virus software on Linux.
