This problem is cause by a virus. When the user tries to log in to the Orkut, a message is prompted as follows.

This is a problem caused by the virus called Heap41a.exe
To solve the problem temporarily, follow the steps,
Press Ctrl+Alt+Del to wake the Taskmanager
Go to the process tab and watch for svchost.exe
svchost.exe is a system process actually
but the virus will be working with the same name as processes
Now search and find svchost.exe with your current logged user name.
Not the svchost.exe with other such as LOCAL SERVICE, SYSTEM, NETWORK SERVICE
Right click the svchost.exe with current user name and Click end process.
Thats it! Now you can log into your Orkut account.

But the problem can occur again because the virus is still on your system. To permanently solve the problem, follow the steps

open my Computer on your desktop
Enter c:\heap41a on the address bar
This will show a collection of hidden files along with a file named svchost.exe
delete all the files by pressing Ctrl+A and then Shift+Del
If your are not allowed to delete the svchost.exe, first do the endprocess procedure we explained before, and continue with deleting again.
I strongly insist you to use an anti virus and antispyware to make your system free of viruses and spywares.
