Virus is a program that attaches itself to a file and spreads to other files
What is virus in a file?
File infector viruses infect program files such as applications, games, or utilities. They are frequently memory-residents, which means that once executed, they remain active in the computer's memory and can infect additional programs.
A typical virus usually (but not always) adds itself to the end of a program. In that case, the host program's size grows due to the addition of this extra (viral) code. To execute the viral code, the virus overwrites the first bytes of the file with a "jump" instruction, which causes the execution to jump to the viral code. After the viral code is executed, the virus repairs the first few bytes overwritten by the virus in order to restore control to the original file. Thus, a typical virus (unlike a worm or Trojan) must rely on a host program to survive and function.
Is it possible to remove a virus from a file?
If there is no backup and no knowledge of how to repair the infection, the anti-virus sends the infected file to quarantine or permanently deletes the file from the computer. In the case of simple infections, the anti-virus must first restore the original bytes overwritten by the virus code.
Hence to conclude that we can remove virus from a file by using above methods

What is interrupt checking?
Interruption testing ensures that an app handles interruptions without failure or anomaly. When used by real users, each app must coexist with other device functions. This means that every app must be optimized to deal with these device functions while running at all times.
Simply put, interrupt tests allow you to examine your app's behavior after certain events that disrupt its flow. In many cases, Android and iOS handle things for you, which is why teams frequently forget to perform this type of testing. However, in order to provide your users with a positive experience, you must ensure that your app always behaves as expected. Because these expectations do not have to be the same for every mobile app and function, you must define and test them yourself.

What is depreciation?Depreciation is allocated so that a fair proportion of the depreciable amount is charged in each accounting period during the asset's expected useful life. Depreciation includes amortisation of assets with a fixed useful life. New assets are usually worth more than older ones.
Depreciation is a measure of how much an asset loses in value over time due to wear and tear and, indirectly, the introduction of new product models and factors such as inflation.
