The new beta version of IObit Malware Fighter, detected more malware and PUPs than Bitdefender did, when scanning a very large older malware collection and a collection of PUPs. This is in no way a recommendation of the product and I presume if tested against recent malware, Bitdefender would detect more.
Advanced SystemCare should (in theory) never delete valid registry keys. Old versions had issues with false positives. But a number of years ago, I got IObit to fix it and current versions should always be safe to use. If you enable the Deep Clean function, then it will sometimes delete needed keys. But that option is disabled by default.
IObit has had a rough history however and I am glad that they finally improved that protection to not be bad as even last year's product. They use to do the worse in tests against malware so it is nice to see them listening to feedback. If they continue to improve then I will redact my statement and modify it, but my statement is based on the information from Iobit's earlier versions and history of products. I am not saying the product is bad at the moment,( for me it is very good value), but my criticism is based on the facts generated over the years from testers and my own experience. If they managed to make a good product this year, then I am glad, but we cannot ignore their history however. They still do not have zero day implemented in the Advanced System Care Ultimate and their Advanced System Care Ultimate still relies on Bitdefender's signatures which Bitdefender being very good is nice, but they only update it once a day while products like Kaspersky and Bitdefender update every hour with signatures if needed. Their registry cleaner has become more safe, but it still relies on trial and error and registry cleaner if you knew are not needed as registry cleaning does nothing to improve performance at all unless your system is older than 2006, or if your system had a virus. They have some nice features and their advanced system care in my opinion is the best optimization software and their smart defrag is the best defrag software in my experiences, but I am speaking on terms of their antivirus history and their controversies like them stealing signatures from Malwarebytes still makes me wary.
I have edited my last statement with evidence to prove just how bad Iobit has been the past few years as the beta shows promise, but it fails because of the signature implementation. Iobit's engine is actually revolutionary and many antiviruses like Kaspersky have actually been inspired by the cloud antivirus system, but Iobit's signatures still held it back and if based on your facts that they have actually made their signatures better, then I would be glad to try it myself.
