Whenever I am downloading a software then this so called Optimum Installer pops up on my Windows 7 computer. I have Microsoft Security Essentials and have tried to scan the pc to remove this infection but nothing is found on my computer. Now matter how many times I try to download any application then Optimum Installer will take over the installation. So, if anyone knows how to get rid of this malware from my pc once and for all, it would be helpful. Thanks
