I think Trustwallet works closely with the contract security auditing companies AvengerDAO and Hashdit. You can find out the malicious level of the contract address you want to link to from the announcement history of these two companies.
The funny thing is I have used the platform before and things went smoothly, I never got this same warning at the time, I think it's just a month ago.
If you believe that these 2 audit firms are credible enough, then heed the warning. If you are more confident it will be fine as before, then go ahead. Just think if some things have changed since your usage last month and a vulnerability was detected minutes before this warning.
