I get this Microsoft .NET Framework start up error.

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you clock Quit, the application will close immediately.

Conversion form string "2/29/2009 6:19:30 PM to type Data is not valid.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the section.
The application must also be compiled with debugging

For example:

< jitDebugging="true" />

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

If you don't know the answer, don't post some google search...

What you have is a trojan. Here is a site that has some info on it:

Just delete the host.exe in your C:\windows
You should also check your registry files, read the link I posted and check the More Information tab.

What happened is that whoever made the trojan messed up and put an invalid date, so it's going into debug mode.
