Windows 7: Microsoft .Net framework error unhandled exception

I just had to rebuild a server that was hit with a Cryptovirus. One of the users (on a new profile) is receiving this error when starting logging into Quickbooks, or restarting. She cancels out and everything works fine.  What is the best method to combat this?

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 system.windows.forms section.
The application must also be compiled with debugging
enabled.
 
For example:
 
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
 
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.

Try the .NET Framework Verifier to see if it can repair .NET

http://cid-27e6a35d1a492af7.skydrive.live.com/self.aspx/Blog%7C_Tools/netfx%7C_setupverifier%7C_new.zip 


Select the newest .NET Verifier, download and run it see if it can repair .NET. If supports:

.NET Framework 1.0
.NET Framework 1.1
.NET Framework 1.1 SP1
.NET Framework 2.0
.NET Framework 2.0 SP1
.NET Framework 2.0 SP2
.NET Framework 3.0
.NET Framework 3.0 SP1
.NET Framework 3.0 SP2
.NET Framework 3.5
.NET Framework 3.5 SP1
.NET Framework 4 Client
.NET Framework 4 Full
.NET Framework 4.5

If no, then remover .NET (Programs and Features, Windows Features), and restart. Then go back and re-enable .NET and run Windows Updates.

I also ended up deleting the registry key for Quickbooks web connector. Between that and the re-enable/update of .Net regained full functionality.
