Is pricegong.com Safe?

One of the best tools I have downloaded it saved me a lot of money till now, I'm not sure why there are complains about it, it easy to use and if you don't need it you can disable it or uninstall it very easily and re-enable it when you need it again.

This may not be the right category, but somehow this happened So I was searching some stuff, but then I saw this warning thing and it had numbers for like a second or two. Then I get pop ups everywhere! It was like adware land! I was using chrome and had adblock so I was questioning why would this happen? Because then if i didn't have adblock I would of marked it as adware. Okay back to the story, I checked my plugins and i saw this thing that said pricegong. The description said, are you curious? I was scared to heck. Not only that but in my installations it said pricegong! I never installed such a thing! And my antivirus was having some "issues" opening.

Site gave me a Browser Add-On but packaged it as an update for a multimedia player I use. I don't care if other people find it useful, it isn't useful when you do not want Adware on your PC. No one likes to be the target of deceit as it's never done for good intent.
