Is IOBit Security 360 worth the risk?

Do you have an opinion on iobit.com? I use their anti-virus software, but I'm worried now by comments from Malwarebytes: IOBit's Denial of Theft Unconvincing . I used the software as it was on a Computer Shopper DVD, and I was using their maintenance tool, Advanced SysCare. Its "System Optimisation" really does work (my anecdotal experience on several PCs). Martin Day In its user forum, IOBit responded with a denial of Malwarebytes' accusations and then said it had cleaned up its database "to remove all disputed data". It is currently hosting 58 pages of debate . But I think you should stop using IOBit Security 360 because it doesn't seem to be very good -- according to this PC Magazine review -- and because it's not on the VB100 list. ( Virus Bulletin provides independent testing of anti-virus software.) It's not worth taking a risk on an unknown product when there are so many good free alternatives such as Avast, AVG Free, Avira AntiVir, Microsoft Security Essentials and many more. There's a Virus Bulletin chart that will help you choose a replacement. I have not used IOBit's Advanced SystemCare Free, but I think Windows tuners can do more harm than good. The only one I use myself is CCleaner (formerly Crap Cleaner), which you can download free via http://www.ccleaner.com/download (If you are asked for money for CCleaner, then either you have the wrong program or you have downloaded it from a scammer. You can donate to support CCleaner but it's free.) Advanced SystemCare Free is quite highly rated as a CNet Download so it probably is not an immediate risk. However, IOBit must know that if users don't trust its anti-virus software, then in the long term, they probably won't trust any of its software. It should aim to re-establish its credentials by getting independent verification and testing of its anti-virus software. Declarations are not enough.
