Well, not all IOBit Products are evil, guilty and unreliable... Anyway, SmartDefrag is fairly good
And 'Chinese'... It's not the point, I've never seen a single user of IOBit among my domestic friends (in mainland China), no need to be 'sad', serious.
PS: MBAM is not so fantastic as what has been described in hosts of posts. In China, I don't think it is able to detect 50% viruses on circulation. In accordance with a test (informal), even one month later, the detection rate of MBAM is as low as 58%, compared with avst! 97% and ESET, Avira,Panda, Kaspersky , etc., whose detection rates are all over 93%. (Viruses based on a list collected among a whole month)
It hasn't marched into China, well, this might be one of the reasons. But even before Avira marched into china, its detection rate was the highest among all AVs (heaps of false positives, though), hence the only thing to blame seems to be its technology.
