Information Security

Interesting versions about the metrics that they can check in order to decide to show me this.

Oh!
We had to block your IP for security reasons. Right now, you cannot use Yandex.Money from your computer.
What to do:
1. Check your computer with an antivirus.
2. After checking, wait 12 hours.
3. After 12 hours, return to our site.
If after completing all three points you still have questions, you can write to us: [email protected] In the letter, be sure to indicate your IP: 000.00.00.00 "

Answer 1

Someone parsed / brute Yandex from this IP, so he banned.

Answer 2

Are you not through a proxy by any chance? In this case, they may also not let you in ... And so Denormalization told you correctly

Answer 3

There were too many requests to Yandex from your IP address and he thought that you were a bot, or a virus program was running on your computer that constantly sends requests to Yandex. In fact, most likely, you have a gray IP address and many people use it, that is, many requests are sent from one IP address, and Yandex thinks that this is one person / bot, but not several.
Call your ISP and notify them and also ask them for a white IP address.

Answer 4

The best psychics work in the Yandex team. Well, or whoever else uses IP, well, actually viruses.
