you should start with running adaware 6.0 on your computer...Flt.dll is realted to spyware and is the cause ogf the problem you are having... If you run adaware 6.0 this will remove it from your system.

When you configure adware you need to scan the registry as well as the computer...

You can alternatively go into regedit and search for flt.dll and remove it manually, but back up the registry first before going into that option...

Once you have remove the flt.dll keys from the registry you can delete the file from the location in c:\program files\flt and the file flt. dll

Here is the link for adware...
