Problem With Advanced Windows Care2/IObitSmartDefrag

I had both of Advanced Windows Care2 and IObitSmartDefrag Installed on my system for about 3 months when at the time of this post everything went down hill. I was in the middle of scanning with Advanced Windows Care2 when avast! pops up and says a Trojan was found in Advanced Windows Care2. I tried all the options it allowed but in the end only Delete all went through then about 3 minutes after that my Scheduled Defrag with IObitSmartDefrag started and was stopped by avast! with a Trojan and the only option that worked was the Delete all. I loved using these Programs :'(. I was Wondering if anyone else got this same problem or if it was just me. I tried redownloading Both Advanced Windows Care2 and IObitSmartDefrag but avast! makes me abort the downloads.
Any help would be extremely welcome. ???

As a workaround, you can add these files to the Standard Shield provider (on-access scanning) exclusion list.
Left click the ‘a’ blue icon, click on the provider icon at left and then Customize. Go to Advanced tab and click on Add button…
You can use wildcards like * and ?. But be careful, you should ‘exclude’ that many files that let your system in danger.
