The thing is that I have read some information regarding IObit,just googled it,the founder was sued by Malwarebytes at few years back hence it cannot do business 'directly" in USA., if you know what's that meant,all of glorified claims in its sites are all bogus and unsubstantiated,I certainly not going to encourage a company installed its software,let alone pay for it. I am better than that. I don't need repeat on Wise's parts.
Educated yourself well,you don't need any of software from this kind of fancy system enhanced software,it's simply just for the noobs who are lazy or don't know how to optimize their system in professional way. But if you must,please choose the endorsed ones by reputable company,like Stardock.
