I had 1.2 BTC stolen. I was making a transaction and properly copied/pasted the beneficiary address. Apparently, someone put malware on my computer which changed the receiving side address automatically. Going out of my mind. At first I thought my wallet was stolen, but realized whenever I copy/paste a BTC address, it just changes it to some other address belonging to the hacker.
There are so many malware software programs to choose from (Bit Defender, AiroAV, Avast, Sophos, Mcafee, etc). Can you please tell me which is the best antivirus software?
