Will Active Protection (Ransomware) Slow My System?
I am interested in installing Active Protection on my system currently running ATI 2018, However, I'm worried that this program running in the background will result in a slower response.
I understand this product is free and will run with my ATI 2018 install.
I'm also concerned that a ransomware intrusion will still have a chance of encrypting my USB external hard drives and my NAS, making recovery impossible. Is that true?
Show me your thumb, you stumble bum bum.
There's no way to know for sure. It does add startup services and scans for ransomware behavior so could impact some.
I'm using it with Windows Defender, Malwarebytes and Macrium (which both have their own version of ransomware protection too) and boot time and performance is still lightning fast. However, my system runs off of a speedy PCIe NVME Samsung 970 EVO Plus, 32GB of 3000Mhz Corsair Vengeance Memory and an OC 4.3 6th Gen i5 cpu. I imagine that hardware and OS health could provide different results for different people though. But if you have a healthy OS and are using a SATA 3 SSD and not low on memory, it should feel pretty similar to how it runs now.
Yes, ransomware can attach to any data that the OS has access too - external drives, NAS shares, etc. It basically encrypts the data and holds it hostage for payment... deleting little by little until the timer runs out. The absolute best way to secure against ransomware, would be to power down the PC and take an occasional "offline" backup with an external drive - one that only ever connects to the PC in this manner and just for these backups. Then shelf it and only use it when it's time to do the next offline backup.
For everything else, ransom protection running within the OS should be the daily line of defense, live AV is for other types of malware.
