Stupid people
I don't know about hate but there's a few things i dislike immensely, Dishonest honest people, people who use other people for their own personal gain, child abuse, animal abuse, people that hide behind religion, habitual Liars, disrespectful children, spammers.
I could give a long list, but since you said " one thing " , I'll say ticks.
Mean spirited people.
being bored.
I hate buying something and then finding it cheaper else where, weighing the concept of returning it by plugging in time and gas mileage as a factor.
Dishonest honest people and those people who don't give respect others.
When something I want doesnt happen.
Just hate ransomware and every other malware that trick people personal information and money.
My sister received the ransom note on Tuesday. It popped up on her computer screen soon after she’d discovered that all of her files had been locked. It announced, “Your files are encrypted, to get the key to decrypt files you have to pay $300 USD. - Cryptolocker"
It also mentioned that if my sister failed to pay within a week, the price would go up to $500. After that, her decryption key would be destroyed and any chance of accessing the 5,726 files on her PC — all of her data — would be lost forever.
Then I have done some research. Ransomware is a malware that blocks the victims' access to their files, and the only way to regain access to the files is to pay a ransom. What's worse, you won't get your locked files or data back even when you pay them! And in this case, CryptoLocker is a ransomware trojan, spawned a few clones — CryptoWall, Crypt0L0cker, and TorrentLocker.
Except for regretting not to have everything backup, we should take more measure or malware protection to block or limit the impact of cyber attacks on our data.
