@Ree81 Pirated software is often just a trojan horse.
If the malware isn't in the main software it is usually in the keygen.
If you stick your head in the Lions mouth, don't be too surprised if it bites.
Note: you did not DL the malware from the Piratebay site. You downloaded a torrent stub which has no malware in it.
The malware is downloaded from all the computers you connect to with your torrent program.
It requires the use of a different program to use, so it is not possible for Vivaldi to block or warn you about individual threats.
I use Shareaza for my download manager as it supports reviews and checking files with Virustotal.
If you have issues about not being warned, perhaps you should take it up with the authors of the software you use.
I could tell you safer ways to steal from software authors, but I think you need to concentrate on getting all your accounts changed to multi-factor authentication, wherever they support it.
Get your ass over to https://haveibeenpwned.com right now and see how many of your accounts are available for sale.
You need some extra indicators for what behaviour a site may contain, so I suggest you install the Web Of Trust extension (you can use it without creating an account).
OPSWAT browser extension will also check sites against several reputation sources, and will do Virustotal style scans of files you DL via the browser.
As suggested already you need to consider a decent antivirus.
As you want free stuff, you should choose between Avira, Bitdefender and Kaspersky.
However, antivirus is the last line of defence, not the first.
You need to learn about safety online.
Until you get a better AV, use this tool to select a higher level of protection with windows defender https://github.com/AndyFul/ConfigureDefender
