Think that there isn't because there is not. Listen to dominic23

It's best to describe the problem, if you have one, in as much relevant detail as possible, rather than what you think is causing it or how you think it should be solved. Running an application you've never heard of on the advice of an anonymous stranger who doesn't even know what your problem is would not be the right approach. That's how you get infected with "viruses," not how you remove them.
