    SAY GOODBYE WINDOWS PC DEFENDER!!! I have downloaded so many virus programs to get rid of PC Defender that did not work!

    Malwarebytes’ Anti-Malware WORKS!!! Thanks so much to the owners/creators of this program the only one that really worked! So many claimed to work on this particular pain in the neck pop-up garbage but did’nt. Sorry but i’m so freaked out that after months of trying other programs Malwarebytes’ Anti-Malware found it and deleted it. Thanks again!!
