You know your computer has a virus by symptoms like slow performance, frequent crashes, unexpected pop-ups, unknown programs or toolbars appearing, your antivirus disabling itself, or strange activity in your email/social media accounts, indicating it's using resources or being controlled by malware. The best way to confirm is to run a full scan with reputable antivirus software like Norton, Malwarebytes, or Windows Security (Defender).
Common signs of malware, viruses and cyber threats on your device
The best and easiest way to remove viruses is by using an antivirus solution designed to clean your system safely. If a virus is already on your computer, however, you may need to run this program under very specific conditions. If you're lucky, the virus may just be sitting in a program you recently installed.
What Is a Computer Virus?
Steps to Run a Full Scan using Windows Defender
Click on the shield icon, which is labeled as Windows Security. Click on Virus & threat protection. Select Scan options. Click on Full scan, then press the Scan now button.
Symptoms of a viral infection depend on where you're infected, but some common ones include:
Microsoft Defender Antivirus continuously scans your device for potential threats and takes immediate action to neutralize them. This proactive approach helps to prevent malware infections and keeps your device running smoothly.
Frequent system error messages occur. Unfamiliar icons are added to the desktop. The system performs slowly, especially while browsing the Internet. Browser windows close unexpectedly or stop responding.
How long will a computer virus last? As long as it is not terminated (manually or by some automatic anti-virus software), except the case where the virus has been programmed to self-destruction that is activated by a trigger event (that can simply be a timed delay, or some more complex conditions).

Symptoms of Malware
By rebooting, you effectively shut down all programs and processes, including any potential malicious ones. This can not only halt the activities of such software but also make it easier for your antivirus software to detect and remove them, improving your computer's security and helping to protect your valuable data.
If you don't have antivirus software on your computer, any virus alert you come across is fake. When you do have antivirus software, only trust alerts that appear in a window from your software.
Most computer viruses are legacy threats that can be easily removed by antivirus software with access to the latest virus signatures. Your antivirus program will scan your system, detect any viruses, and offer to quarantine or delete the files.
Basically, a virus is a computer program written by a person with the goal of damaging or taking control of another person's computer. They get onto computers the same ways normal programs get on, by downloading them from the internet or from infected storage hardware.
The main difference between free and paid antivirus tools is that paid solutions generally offer more robust security. Most free programs only give basic protection, but a paid antivirus often includes advanced features like enhanced malware detection, customizable scans, and dedicated customer support.
You can tell if your computer has a virus by looking for warning signs, such as slower performance speed, increased pop-ups, frequent crashes or freezes, reduced battery life and unfamiliar files. A computer virus is a type of malware that requires user interaction to infect your computer.
