Is there any strong antivirus I can use to safeguard my PC from malware? I have few coins that runs wallet only on PC but it's very easy for PC to get compromised that's why I'm looking for a safer tool that can fight Trojans and malwares.
Antivirus is not magical protection against malware, and they often can't protect you against phishing, clipboard threats or from your own mistakes while browsing internet.
If you want to secure your coins you can use separate offline computer, it can be cheap old laptop or desktop computer with Linux OS, Raspberry Pi or hardware wallet.
It's very rear to see antivirus for Linux so I would suggest switching from WiDd0ws to free Linux OS, but if you don't want to do that try Malwarebytes free version.
