  • Tyrese31

    I just could not stand these fake alerts. So hard to close them! It took me a while until I reached google page and looked for a removal tutoriam because i constantly had to stop to close the pop-ups.

  • BentleyZ23

    I managed to uninstall it manually!
    By the way, why no one have mentioned that these pop-up alerts play a sound message too? I had to turn off my speakers all the time because it was so damn annoying!
    Whatever, now its gone, so no worries. Just need to be more careful when installing new apps… some of them carry computer parasites, as you can see!
