[Solved] Best antivirus against ransomware

As per my knowledge, I suggest you ESET has the best protection against Ransomware.

Bitdefender does a good job against ransomware.

To fight ransomware, anti-virus software alone is not going to be enough. Because many strains of ransomware emerge regularly and an antivirus working on signature based detection won't be able to keep up with all of them. What you need is the whole Internet Security suite, which is basically an advanced version of antivirus. Like, for example, the Comodo Internet Security (CIS). Because security products such as these usually contain cloud-based malware-analysis, which is pretty effective against ransomware and any other such modern-day malware.
