the expresscache software puts a propriatary file system the ssd. if the AV somehow sees it and is trying to scan it would not be able to understand the file system. Not sure why it would even try to scan it as the RC SSD does not even show as a drive anywhere aside from disk managment.
all you need to do is delete the partition on the RC SSD. Once you install the new HDD and OS just install the EC software and it will take care of setting the RCSSD up for you.
