Virus attack: Files are encrypted and have '.crypted' extension

Hello,


My computer has been hacked with some kind of encryption virus and most of the files are
encrypted with '.crypted' extension. Could anyone please suggest what needs to be done to remove
the virus. This attack happened after a couple of days of the "dllhost" virus attack, and when my
computer's wi-fi was left on for a couple of hours (dllhost was active and attracting more viruses only when I my internet connection was on). I have taken outside help to remove the "dllhost" virus but unfortunately they were not able to decrypt the files.


Any help or suggestions are appreciated.


Thanks.
