Thanks for the questions.
To clarify, during the trial period STOPzilla's real-time protection will quarantine any threats that are running in memory. This helps prevent any further damage to the computer. Any dormant threats are detected during the scan but not quarantined. Both are presented to the user in the scan results. If the user chooses to purchase STOPzilla, and chooses to "Remove," all threats are then quarantined, which can then be purged for complete removal.
If a user chooses not to purchase, the quarantined threats remain in quarantine, and the dormant detected threats remain on the computer. Once the trial period has expired, STOPzilla's real-time protection becomes disabled, which would leave the computer vulnerable to new threats. We strongly recommend registering to allow all threats to be quarantined, and purged.
Regarding the WOT, we are definitely lacking there. Improving our reputation is something we are working on right now. I do appreciate the feedback!
