Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

your going to want to check the MX records for your domain name. That is likely controlled by your registar or web host.
Does your exchange communicate out the same IP as the rest of the machines on your network, or do you have a separate live IP setup in a 1:1 nat just for that exchange?
No its recommended, it just doesnt install with the lite package for some reason. I often overlook installing the ad blocker.
Re-run the speed test with the attack blocker turned off.
