What you are dealing with is a computer virus. Get another computer, and restore the seed phrase on that computer, reinstall the infected computer (because anti-virus is so awful at detecting viruses in the first place that it just kills running programs).
If it is a computer virus, OP should use Internet security, antivirus software to have better protection.
The best protection is don't do stupid things when surfing on Internet and don't use cracked softwares. It is a first barrier against hackers. The second layer of barrier and protection is software.
Op said he used Trust Wallet. which is a mobile wallet. So why can a computer virus cause a problem here? And I don't think any kind of virus can cause such problem. But if there are constant coin transfers from his wallet and the OP didn't do it himself. Then it can be said it is completely hacked. And he should stop using that wallet immediately.
