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.
  • Breach of privacy. In some cases, viruses seek to gather personal information about you for the purpose of identity theft or fraud. This can result in financial losses if your accounts are breached.

Key takeaway: A computer infection can cripple your operations with a loss of performance, functionality and information. It can also result in a breach of privacy and exposure to other negative software.
