Software that infects a computer and is created by computer code is called a "Malware, or malicious software"
What is a Malware?Malware is any program that is purposely meant to disrupt a computer, server, client, or computer network, leak private information, obtain unauthorized access to information or systems, deny access to information, or interfere with the user's computer security and privacy.
Malware often infects a system by deceiving users into downloading and/or installing software from the Internet that they should not.
Follow these simple procedures to manually remove malware from a system: Download and save to a USB drive a malware-removal program such as McAfee Stinger (or another equivalent product from a major antivirus provider). Depending on the virus, you may need to utilize more comparable programs.

Which trigonometric ratios are correct for triangle DEF? Select three options.
The trigonometric ratios for triangle DEF are
sin(D) =24/25, tan(D) =24/7 and sin(E) =7/25.
What are trigonometric ratios?
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), and cosecant (cosec) (sec). Trigonometry, a field of mathematics that deals with geometry, is the study of a right-angled triangle's sides and angles.
Trigonometric ratios are real ratios used in mathematics to link angles of right-angled triangles to side length ratios. They are widely used in all fields of geometry-related science, including geodesy, solid mechanics, celestial mechanics, and many others.

What is the decimal value of 54 (base 10) converted to binary and 2's complement?
"The decimal value of 54 (base 10) converted to binary is 110110 (base 2).
What is binary?A binary number is a number expressed in the base-2 numeral system or binary numeral system.
To convert a decimal number to binary, we can use the following steps:
Divide the decimal number by 2 and record the remainder (0 or 1) as the least significant bit (LSB) of the binary number.
Repeat the process with the quotient until it becomes 0.
Write the remainders in reverse order as the binary number.
For example, to convert 54 to binary, we can do:
54 / 2 = 27, remainder 0 -> LSB = 0 27 / 2 = 13, remainder 1 -> next bit = 1 13 / 2 = 6, remainder 1 -> next bit = 1 6 / 2 = 3, remainder 0 -> next bit = 0 3 / 2 = 1, remainder 1 -> next bit = 1 1 / 2 = 0, remainder 1 -> MSB = 1
So, the binary number is 110110.
To convert a binary number to 2's complement, we can use the following steps:
If the binary number is positive (MSB = 0), then the 2's complement is the same as the binary number.
If the binary number is negative (MSB = 1), then the 2's complement is obtained by flipping all the bits and adding 1.
For example, to convert 110110 to 2's complement, we can do:
Since the MSB is 1, the binary number is negative.
To flip all the bits, we change 0 to 1 and 1 to 0, so we get 001001.
To add 1, we start from the LSB and carry over if needed, so we get 001010.
So, the 2's complement is 001010.
Note: The 2's complement is a way of representing negative numbers in binary. It has the advantage of allowing addition and subtraction to be performed using the same hardware. The 2's complement of a binary number is the inverse of its 1's complement, which is obtained by flipping all the bits. The 2's complement of a binary number can also be interpreted as the negative of its 1's complement. For example, the 1's complement of 110110 is 001001, and the 2's complement of 110110 is 001010, which is also -001001."
