SecureAPlus is anti-virus software in Singapore. The pro version integrates 11 engines, and the Home version integrates nine engines. Now the revised version is officially released. After the revision, it was renamed CatchPulse Free, CatchPulse, and CatchPulse Pro. CatchPulse Pro can be used with cloud control on the enterprise side. CatchPulse has always had an education support plan. It's still very good to register your account by email and activate it to use it for three years. I've been using it for a while, and the overall occupancy is very low, and the scanning and monitoring sensitivity is relatively dependent on the network. The scanning and monitoring engine often reports viruses with its apex, Double-A, and em, while other engines do not frequently report viruses. The CatchPulse removes the switches of all engines in the settings and only gives one button to the cloud engine. During installation, apex, Cloud Engine, and UA can be installed optionally. It is recommended to install all of them. CatchPulse Free has no application control module. CatchPulse Pro has more cloud control than CatchPulse, and everything else is the same. Compared with the old version, UI is much simpler and cleaner.
