I disagree with the lucky
I received the reviews on IObit from several reputable sources and have used it on many different computers. I must respectfully disagree with being lucky. I have never experienced anything negative with IObit at all ever. Neither have most IObit users who rate it online and in PC Mag, and in fact it was the PC magazines that offered the reviews and free downloads via discs.
I am not sure what others do here, but I teach programming and get to speak with experts on security software in my work, and they have said great things about IObit and MalwareBytes and Cookie cleaner which I use and found for free downloads on both CNET and discs from computer magazines.
I never have seen a browser bar installed if I did not want it.
