User Review

"We have not had a problem since using your products."

"We used to use up to a dozen different programs to keep our machines running smoothly and keep the bad guys out. It took hours every week to maintain security and performance. Now, with IObit Malware Fighter Pro and Advanced System Care Pro, everything is in one place and it takes us just a few minutes every couple of days to do the same jobs with much more confidence. We have not had a problem since using your products."

"I also had other programs for this purpose installed, but IMF always finds the problems first and blocks them."

"Some years ago somebody drew my attention to IObit Malware Fighter. First I was sceptic. But after installing it, it became my favourite anti-malware program. It is very easy to use. Through the years it already has detected several threats and removed it. In cooperation with the other IObit programs, like for example ASC, I have a good PC protection. I now recommend these programs to all my friends and family."
