Hey there
The first one is regarding the permission/ability for a google to scan your website. By scanning, it gets the keywords you use in it and determines if your website is not malicious, or simply, not obeying their TOS.
The second one is there because, at some point, the crawler did pick up some nasty keywords/URLs and determined that it is malicious. My guess would be that that error arose before the first one.
To be fair, I cannot tell you more about this issue, but I would like to know what exact emails have you received from Google regarding those problems. That would be the first step in solving them.
Anyways, feel free to hit me up so we can talk more about this. I am very responsive. All the best
