Regarding the locking of keys, most people complain about it, and I can understand this sentiment. However, if we put ourselves in their shoes, locking keys is also reasonable.
Now, during these turbulent times, an ultra-powerful tool to resolve key lock issues (Kaspersky Blacklist Removal Tool) has emerged—it's truly a helping hand when we need it most. Therefore, "For every advance in righteousness, there’s a greater rise in wickedness," and I’d like to share this with all Kaspersky users!
Usage method: Once you receive a notification that the key cannot be used or that the key is incorrect, you can run this tool. Then, after restarting your computer, you'll find that Kaspersky is like new again, and you won't receive any more notifications about the key being invalid.
Note: Do not use this tool unless you receive a notification that the key has been locked.
