Cloud analysis can take a little time, but if it determines that the program is malicious, Webroot wipes out the program itself and rolls back any system changes. It sends details about any unknown program to the cloud and also lets that program run in a bubble, virtualizing any system changes so they don’t become permanent. Like most antivirus tools, it wipes out known malware on sight, but unknowns get special treatment. Webroot’s local presence can be tiny because its intelligence is in the cloud. Back when diskettes were common, you could fit it on just one. Without question, Webroot SecureAnywhere AntiVirus is the smallest antivirus we've seen. Now you can sit back and do, well, anything you want! If you want maximal antivirus protection with minimal interaction, just fire up Bitdefender Antivirus Plus and turn on its Autopilot. But, overall, this is a marvelous choice for antivirus protection. And if you want unlimited use of the VPN, you must pay a bit extra. The password manager doesn’t have all the fanciest features, for example. And its Autopilot feature means that all this happens with minimum bother for you, the user. Its ransomware-specific defense system proved itself in testing, too. The independent testing labs routinely grant it perfect or near-perfect scores, and it aces many of our hands-on tests. Not only that, but it’s also a good antivirus. While its name says antivirus, this product's feature list beats many security suites. Ransomware protection, a hardened browser for your financial transactions, VPN protection for your connections, a feature that smacks down ad trackers, automatic detection of missing security patches, a simple password manager…the list goes on. The Plus in this case represents a multitude of features.
