The negative impact of a computer infection

A virus or malware always has a negative impact, but the degree of that impact depends on the type and scope of the infection. Here are some of the possible consequences of a computer infection:

  • Loss of performance. Malware can make your computer process things more slowly. That means it may take increasingly longer for you to get work done or just look up a quick fact.
  • Loss of functionality. In extreme cases, the virus can degrade your computer performance or programming so badly that you can no longer use your machine.
  • Exposure to other negative software. The purpose of some malware is to entice you to download even more dangerous software.
  • Loss of information. Viruses might delete stored files or data.
