What are the most interesting programming language footguns?

Programming language "footguns" refer to features or quirks in programming languages that can lead to errors or unexpected behavior, often causing significant issues if developers are not careful. 1. JavaScript - Type Coercion JavaScript footgun JavaScript’s automatic type coercion can lead to surprising results, like [] + [] resulting in an empty string, or [] + {} returning "[object Object]". These quirks can cause unexpected behavior, particularly in conditional statements or arithmetic operations. 2. Python - Mutable Default Arguments Python mutable default argument In Python, using mutable objects (like lists or dictionaries) as default arguments in functions can lead to unexpected results because the default value is only evaluated once. For example, if you append to a list default argument, the default list will retain its value across multiple function calls. 3. C - Buffer Overflows C buffer overflow C gives programmers direct memory management capabi...

My laptop was hacked recently. The hacker successfully penetrated McAfee's internet security disabled the real-time protection, antivirus, and VPN. They are remotely controlling my laptop every time I connect to the internet. What can I do?
