Kill Viruses for Security Concerns

In today’s era, where information and science are well-developed, almost everyone is aware of the danger of viruses and the importance of killing viruses. But do you know what time is the best time to kill a virus?

The Best Time to Kill Virus

Knowing that viruses may further ruin the data and operating system after their invasion, most of you think it would be better to kill viruses as soon as you can by using powerful antivirus tools.

However, I don’t suggest you to do so. On the contrary, I recommend you try every means to recover files deleted by virus attacks first before performing any other operations because antivirus programs may delete useful files from your computer when removing viruses for you. And this may cause secondary damage, deleing more files from the computer and making some data gone for good.

How Virus Enter Your Computer and Ruin Data

With the development of the internet, the risk of being attacked by viruses is high. When you click on links sent from untrusted sites or in an anonymous email, you are giving way to a hidden computer virus.

Other actions are dangerous and may let computer viruses invade your OS:

  • Use pirated or unknown software/programs/applications.
  • Use a new movable device on a computer without checking security or killing viruses.
  • Continue visiting sites on which viruses or abnormal operations are detected.
  • Download files from the network casually, even from unknown sites.

In fact, viruses can get into our personal computers through plenty of new ways. That’s why most users would like to roll up their sleeves and start to install a trusted antivirus program when they buy a new computer or reinstall the OS. After viruses enter computers, they may not be activated right away.

Virus Comes with Storage Media

In theory, viruses are attached to storage media like floppy disks and hard disks so as to constitute an infection source, and the transmission medium is decided by the work environment. A virus is put into memory after invasion and the virus creator has already set up the trigger condition, which is diverse. It could be the clock, system date, user identifier, or system communication. When the condition becomes ripe, the virus will start replicating itself to the infected object and performing various sabotage activities, including:

Definitely, recovering files deleted by a virus attack becomes an urgent thing.


All in all, a computer virus is more than just a data killer since it actually can cause serious problems to a computer’s disk and system. Computer viruses are to computers what biological viruses are to the human body. They can place us in precarious situations, causing concern over the destruction of hard-earned work, the disappearance of cherished memories, financial setbacks, and more.

But you shouldn’t kill the virus immediately after getting attacked since this is a dangerous action to your data. You should finish deleted or corrupt files recovery first and then clean the virus.
