I don't know what have happened until now or if you have gotten your Bitcoins,anyway I just want to add just a little bit to the brilliant examples given ahead in the thread.When logging to your Blockchain.com wallet use a Linux live distro,like Linux Mint or Ubuntu in order to minimize attack vectors during this time as this way you can be sure you are 100% virus free,you never know with Windows even after a clean installation I have doubts.
Brothers I really appreciate your these knowledgeable tips and all information's, but sadly I have few serious troubles just because of this unable to recover my these coins, so now I am feeling these are not recoverable, and I have no option as well just want to thank you all here on this forum as it's really helpful and good place for me and thousands others which are looking for bright side of this crypto community.
As I posted I lost my father after this we have another accident and our house burnt badly so lost of my computer and all other stuff bring me down badly so now trying to recover from this all which is never been easy but still fighting hard hopefully sometime in future I will be good in this field as well thanks again.
