Access to the internet and the opportunity to get a lot of work done on the computer has made life easy for many people. Many people earn their livelihood working from the computer. Using a computer may profoundly affect your life if you are one such person.

One of the worst nightmares you can possibly have is to wake up one morning and discover that you can no longer access your important files on your computer. Viruses and malware are usually the suspects when this happens.

It is better to avoid this experience than to learn the hard way when your computer gets infected by a virus or malware. In this article, you will learn of the early signs of a virus infection of your computer and how with proper internet security, you can avoid them.

Why is Early Detection of PC Virus Infection Important?

Several years after the first computer virus was released, online connectivity has made the distribution of even more computer viruses a daily occurrence. Different malware and spyware incarnations can easily attack your computer, each of which can do significant damage if not prevented or taken care of early. Here are a few ways viruses and malware can affect you:

  • Many viruses and malware on the internet now can negatively affect your computer, study, business, and life.
  • Computers infected by viruses may give signs such as running abnormally slow, acting strange, and other glitches.

Installing and ensuring routine updates on your preferred antivirus software can help to protect you from the harmful effects of virus and malware infections.

The Negative Effects of a Computer Infection

Even if you prioritise small business cybersecurity, detecting a computer infection can be challenging. Cybercriminals are so savvy that they are capable of disguising their work. They can bury malware in system registries from the eyes of their unsuspecting victims so that it is hard to identify or extract.

Fortunately, with some readable signs, you can tell if your computer is under a malware attack and some steps you can take to recover your data and systems.

When your computer is infected by a virus or malware, it can negatively impact it, leaving you vulnerable to all sorts of harm, such as fraud.

However, you need to understand that the extent of the impact will depend on the kind of infection and its scope. The following are some of the possible consequences of experiencing a computer infection:

Degradation of performance

If your computer is infected with a virus, it may begin to process things more slowly. This can generally start hogging your computer's resources, making it take longer to complete work.

Degradation of bandwidth

Botnets are computer networks used to serve a central remote system. They can distribute large volumes of data and consume all broadband bandwidth.

Loss of function

In extreme cases, virus attacks severely degrade computers' performance or programming. In such cases, it may become impossible to use the system again.

Exposure to other dangerous software

Malware is designed to trick you into downloading even more dangerous software. This is done so well that untrained eyes fall into the trap easily.

Loss of information

When a virus infects your personal computer, you risk getting some stored data and files deleted. Ransomware can destroy the computer's hard drive if specific demands are unmet.

Breach of privacy

Some viruses have been engineered to gather information for fraud and identity theft. If your account is breached this way, you may suffer financial losses. You may even have to deal with punitive fines if it is confirmed that your business did not adhere to local and state business regulations.

Different Types of Computer Infections

Computers and networks often face different threats. The following are a few of the widespread ones:

Computer viruses

They are designed to corrupt or attack your computer system. They can quickly spread from one machine to another through shared links, downloaded and uploaded files, or websites that have been compromised. People are responsible for spreading viruses when they share and link without caution or do not use good antivirus protection.


These are similar to viruses but do not require human beings to spread. With how they are designed, they can move from one computer network to another by themselves.

Adware, spyware, and ransomware

These malware are designed to track your activities online, collect essential details about you, steal your data, and withhold it until a ransom is paid.

Signs Your Computer is Infected With Malware

Unexpected pop-up windows

When you continually get unexpected or unusual windows and dialogue boxes, they could be signs your computer has been infected with a virus. Some fake warnings may be issued to alert you of security threats on your computer. What follows is a prompt to call a number or click a link. Legitimate protection software or antivirus programs do not reach people to call a customer service number.

Random sounds

When computers become infected, they may be programmed to give audio signal responses to things you cannot control. Some types of malware may stifle your computer screen so that you cannot see it but begin hearing a warning message from the background. If you keep hearing bells and chimes from your computer, it may have been infected by a virus or malware.

Strange file or folder changes

Some changes may occur on a computer that are signs that there is a technical problem or a virus infection. When files are suddenly lost, or the icons and contents are changed, you should understand that a virus infection is likely at work.

If you experience corrupted browser bookmarks, this should not be regarded as a warning sign. Many times, bookmark icons of browsers such as Chrome become jumbled.

Slow operation

Check and see whether your computer is running slower than usual. If your computer has a hard drive light that is constantly on, or you observe that its fan is working at full speed, you should be concerned. The computer's resources are getting directed from legitimate programs.

Some third-party companies recruit affiliates who trick people into signing up and downloading a piece of software from their websites. These rogue software will compete with applications on your computer, and you will eventually see a slowdown in its performance.

Random connections to unknown websites

Another common type of infection is when your legitimate antivirus software warns you of an application that intends to connect to a website you do not know or have heard of. Your computer can't make connections for you as someone needs to initiate them. If you are not initiating these connections, malware in the background may do it for you.

Unexpected images

Your computer may be infected if you constantly see pop-up ads for some websites you do not visit. Examples also include pornographic images popping up or images from news sites you don't even know.

Inability to download antivirus programs

Although computer viruses are non-living, some are designed with a self-preservation instinct. Most computer users believe the best way to get rid of a virus is through an antivirus scan.

However, it may turn out that the virus starts defending itself when you see that you cannot successfully download and install the antivirus software needed. For some antivirus software solutions, you may have rescue disks for scanning and cleaning your infected computer.

Spam sent from your social media or the email account

Malware is designed to work differently. A type can send random messages to all the contacts on your list. The infection can spread quickly on the internet because it can trick people into clicking on an infected link. This link spreads the malware around to unsuspecting people, who spread it to their contact lists.
