Should I delete this file?

I've been going to my control pannel/ add or remove programs, and I've been getting rid of programs that look unfimiliar to me becuase lately I have been having a huge spyware/adware problem. I've come across this Bar888 and I've never heared of it before and have no idea what it is. So my question is what is Bar888 and should I get rid of it? Thank you.

I Googled it, and it sounds like adware that should be removed. Below is the link I read on it. It has some instructions for removal, though they appear a little complicated.

Good luck.
