Identify if your computer is infected with malware: Malware is a form of hostile software that is used to gain access to personal or business information in a computer. Since it is software that consumes computing power, it affects the proper functioning of the computer system. Many of the threats are not detected as such by protection programs and enter a system undetected. Thus, it is important to identify the symptoms in the computer's performance to find a possible infection.
Recognise symptoms to protect the computer
Every system should use anti-virus and anti-malware software to protect a computer from threats that enter the computer via the internet. Unfortunately, new forms of malware come online every day, which is why sometimes the computer gets infected faster than the antivirus programme can be updated.
If you observe a certain behaviour in the computer performance, you should find out whether the system is infected with malware.
The 10 most common symptoms that a computer is infected with malware
- Lower performance speed. The system is slowed down by additional software activity in the background and this makes the computer less responsive.
- Programmes do not run. The malware can affect certain programmes that are used frequently. These then suddenly no longer start or crash frequently.
The computer starts on its own for no reason or has problems starting correctly. - The antivirus software is not running and the icon has disappeared.
- Some files are blocked, access to certain files on the system is restricted.
- The printer connected to your computer refuses to work or is no longer connected.
- Unwanted windows appear. When the browser is opened, several windows open to display adverts or certain web content.
- The download speed has dropped drastically, but nothing has changed in the connection and no other computer is using the bandwidth.
- Contacts receive emails from your account that you have not created.
- The search engine seems to make random search queries.
Why is cyber security so important
It is advisable and necessary to have some basic knowledge of cyber security to prevent data theft from a computer system.
If a computer is left unprotected, financial information such as credit card or bank account numbers or personal or business documents can be misused. Malware is often used simply to damage a system and cause data loss.
Data, personal or professional, should remain confidential and to avoid infection, the need for cyber security increases.
Is my computer infected with malware? What is malware?
Malware is any type of software designed to damage or exploit another piece of software or hardware. The abbreviation for "malicious software" Malware is a collective term used to describe viruses, ransomware, spyware, Trojans and any other type of code or software created with malicious intent.
Malware attacks can crack weak passwords, drill deep into systems, spread across networks and disrupt the daily operations of an organisation or business. Other types of malware can lock important files, spam you with adverts, slow down your computer or redirect you to certain unsafe websites.
Malware is at the root of most cyberattacks, including the large-scale data breaches that lead to widespread identity theft and fraud. Malware is also behind the ransomware attacks that cause millions of dollars in damage. Hackers target individuals, organisations and even governments with malware attacks. It is therefore very important to regularly check whether your computer is infected with malware.
Is malware the same as a virus?
All viruses are malware, but not all types of malware are viruses. Viruses are a type of malware that replicates itself by inserting its code into other files or programmes and then spreads from one infected computer to another.
To know if an infection is caused by another type of malware or a virus, you need to look at how it works. If it doesn't use other programmes to copy and spread itself, then it's not a virus.
