How to Know If a Computer Is Infected with Malware?

There are various signs that would indicate a computer has been infected with malware of any kind.

  1. Often the machine would be running slower than usual if infection had taken place.
  2. Especially for adware infection, many pop-ups would begin appearing and also interfering with not only machine performance but also user experience.
  3. It is common for a machine to crash often should malware be present. Of course this would be detrimental to the user and in such cases they may well need to replace the machine altogether in case the malware was unable to be eradicated.
  4. Higher volume of network activity, even when the user is not connected to the internet at all, or any other online connections to servers to download or upload any data is present. In such cases, various checks would need to be done to rule out malware infection or any other cause of the irregularity.
  5. Another and more social way of knowing if a user’s computer has been infected is by them hearing from their network of friends or colleagues telling them that they have received unwanted or suspicious messages from the user that they doubt was genuinely sent by them.

In short, any irregularities that are noticed, from unwanted desktop items to a slowing down of the machine, to unusual error messages, all could indicate something is amiss and needs looking into.

Of course, there are also malware that runs silently in the background in order to avoid detection and removal.
