Thanks for reporting this. We have recently moved our websites to a new server via new hosting company and it appears the IP address we were assigned on the new hosting has been already in ESET antivirus's database, probably due to some compromised website that was assigned the same IP before us...
We have contacted ESET to remove the IP, but haven't heard from them yet unfortunately.
Rest assured the webrotate websites are safe. Both storeimaging.com and webrotate360.com.
