Is wextract_cleanup0 safe to let startup?

Just out of the blue my Spy Sweeper is picking up wextract_cleanup wanting to be added to my startup list, so far I have been telling Spy Sweeper not to allow it but of course it keeps trying. I did a Google search and some think it is a Microsoft or Windows program that needs to run and others are not so sure if it should, any ideas? If it shouldn't be allowed to run at startup how would I keep it from trying?
I strange thing also is my moms Spy Sweeper is also picking this up (out of the blue) wanting to install also. Thanks!

 

Let it run. It's a cleanup tool that is included with many programs to clear the files they have used for temporary installation purposes.

After it runs it should not be trying to start upon reboot. If it continues to be in the Startups, dump it.

 

Okay thanks alot!
