Solution Mail ware Preventing Accessing Mozila/Orkut/YouTube

I found a suspicious mail ware in my system which
prevents me from accessing mozila firefox and also orkut and youtube
When i open mozila then a alert box poped up and says
"Use Internet Explorer You Dope" and "I Don't hate mozila but use IE or else ...."
For Orkut and Youtube it says "Orkut is banned for you you fool" "Muhaaaaa"...
So searched internet and i found a solution given by some person in some group
the the solution works ... the solution is :-
Download first hijakthis from Trend Micro
Just Run it .. And it will display lots of processes which are running
in you system look for entries like this
1. heap41a\svchost.exe
2. heap41a\std.txt
Delete These entries ...
If you delete other svchost.exe the windows warning will be seen
and it will restart your system only........
After That Just Use search to search for "heap" tick
the hidden and system folder option then you will be able to see
a hidden folder named heap41a delete it.... If it says access denied
the download and install and use Unlocker.
Thats all i did and it working too..
If It's useful to you then don't forget to comment it.....

Thanks...
