What are the dangers of having viruses on your computer?

There are a lot of dangers involved with having viruses on your computer. From significantly reducing the performance of your computer up to having your files taken by a third party, all of the possible effects of it on your machine are negative. These include the following:

  • Significant decrease in performance – As stated above, viruses can significantly decrease the performance of your computer.

If the virus doesn’t intend to make your computer slower, it may do other malicious things to it instead
  • Loss of information – Some malicious files are targeted towards your information. Because the computer is naturally stored with usernames, passwords, credit card numbers, and other relevant information, some hackers put software that specifically targets these. Once they have access to this, they can then use steal your credentials for identity theft or credit card theft. This should be addressed immediately as a variety of acts can be done by the hacker if left unnoticed
  • Bitcoin mining software – Some of these applications can turn your computer into a literal bitcoin miner. These are currencies which people use to transact online while hiding their identity. Although fully digital, the currency has real-world value and can be used to purchase things. To mine them, one must have several computers continuously processing with their RAM in an act called “mining”. Once your computer is turned into one of these, you may notice a severe decrease in computer speed mainly pointed to its memory
  • Damaged files – The computer can also damage the applications that are currently installed in the PC. It can delete and rename specific files within the computer as to confuse its users. It can also open and close the program whenever it wants without the user’s consent. It may even begin typing random words while you are using the computer. In short, it can take away the freedom of the user to control the machine
  • Total disable – The computer can also fully be disabled by the virus. The hacker can simply destroy the software of your computer without any reasons. Instead of tampering with your files, it can target its operating system instead and make it unable to be used. In this case, the only thing left to do is to do a full reformat which deletes all of the files inside the computer
