These malware numbered about 690, including viruses, Trojans, worms, ransomware, spyware, cryptojackers, rootkits, keyloggers, etc. 

With a single Full system scan, Bitdefender detected and removed every piece of malware on my system in less than one hour.

Bitdefender's VPN isn't as robust as premium VPN providers but does offer a no-log policy, strong encryption, unblocks geo-blocked and restricted websites, fast download speed, kill-switch technology, online safety, and anonymity. However, the 200MB bandwidth limit prevents you from doing so much more with Bitdefender's VPN. To bypass the 200MB bandwidth limit, you can subscribe to Bitdefender's premium antivirus suite with unlimited Bandwidth or subscribe separately to Bitdefender's VPN plan.
