Paying ransom money is not safe

If you are thinking that you can restore your data by paying ransom money to Coaq File Virus then it could be a big mistake. One thing you should understand is that hackers are only interested in cheating your money, that’s why they are threatening to double the ransom fee in 72 hours. They are clearly trying to intimidate victims and forcing them to make a decision of paying without looking for alternate methods.

Attackers behind this virus don’t want you to go looking for answers and seek help from experts. It is not a discount offer given by cybercriminals, it is the bait and timing is the hook. So it puts victims in a rush to pay the money and buy the decryption key at half price.

One other thing that is also very alarming is, that attackers are demanding money through BitCoin. It is a cryptocurrency that is untraceable and, there is no way to find out who got the money. In most cases, criminals often stop responding to victims’ emails as they have neither the reason for giving decryption tools nor the fear of getting caught. So you are advised to not trust the hackers, no matter how desperate you are, and don’t risk losing your money too.
