How to remove the "Internet Security" malware for Windows 8

You could try Malwarebytes ( http://www.malwarebytes.org/products/malwarebytes_free/ ) or Superantispyware - (http://www.superantispyware.com/). If you can, download it onto a USB stick on another computer or you can burn it to a CD to prevent the USB drive from picking up anything nasty

The other thing that is worth trying if you are unable to run your usual anti malware applications (or the ones suggested above) is to rename the applications before you run them. So if you do decide to try Malwarebytes, once you have unzipped/installed the software, find the EXE file and change its name. From memory, Malwarebytes installs as mbam.exe, so you should change it to something like mbamXYZ.exe before running it.

Often this sort of malware changes the registry to block the running of specific software, such as Malwarebytes, so you can't run them and get rid of the malware. Changing the name of the EXE file will bypass this and allow you to run the software properly.

You should try running the various versions of rkill on it.  It kill the software from memory then you can run Combofix and MBAM to clean your system.

If the rkill doesn't work then you'll be forced to use a rescue disk like the one posted above.  Problem is it takes an extremely long time to clean with that rescue disk, that's why I suggested the above.

Quickly?:  Try system restore to an earlier date.

Since your post I am seeing others refering to a similar problem

There are files being renamed from xxxx.xxx to xxxx.xxx.html

Seems the virus encrypts the files and embeds a link in them so if you execute the file it just takes you to the site demanding paymant for an unencryption code

usually it is possible to get at a keycode hidden on the pc and use a decryption program to restore the files but this latest variant seems to delete the keycode.

I am not seeing any fix at all for this at present

If your symtoms look anything like this I would be tempted to backup the disc asap and then leave it completely switched off, certainly keep it off the internet, until a workable solution is found

This gives further insight

Note:grinler is the guy would wrote rkill ( so I think we can accept he knows what he is talking about?)

This was the only solution that helped.  The problem was complicated by the laptop using Windows 8.  It made gaining any control very difficult.  The Kaspersky solution that I used was Rescue Disk 10.  It allowed me to get to the file system and once I was there, I could control some applications by going directly to them.  using a command prompt invoked by a created icon started as Administrator, I was finally able to get the machine in safe mode  where the bug did not seem to work.  There I ran mbam chameleon and it scarfed it up.

Great job - would love to get my hands on the people who write this crap

Still no answer for the xxx.html issue if anyone is seeing snything ?
