What are the common signs of a virus infection on my hard drive?
One of the most common signs of a virus infection on your hard drive is slow performance. If your computer is taking longer than usual to start up, launch applications, or complete tasks, it could be a sign that a virus is running in the background and consuming system resources. Another common sign is the presence of unfamiliar icons, files, or programs on your computer. If you notice any suspicious files or programs that you don’t remember installing, it’s possible that a virus has infected your system.
Other signs of a virus infection may include unexpected changes to your system settings, such as unfamiliar desktop backgrounds or altered system configurations. You may also experience frequent crashes, freezes, or error messages, or notice that your antivirus software is not functioning properly. In some cases, you may receive alerts or notifications from your operating system or antivirus software indicating that a virus has been detected.
How do I know if my antivirus software is not detecting viruses?
If your antivirus software is not detecting viruses, it may be because the software is outdated or not configured correctly. Make sure that your antivirus software is up to date and that you have the latest virus definitions installed. You should also ensure that your antivirus software is configured to scan your system regularly and that it is set to scan all areas of your system, including email attachments and downloaded files.

In some cases, you may need to uninstall and reinstall your antivirus software or switch to a different antivirus program if the current one is not effective.
What is the difference between a virus and malware?
A virus is a type of malware that is designed to replicate itself and spread to other computers. Viruses are typically designed to cause harm to a computer system or steal sensitive information. Malware, on the other hand, is a broader term that includes all types of malicious software, including viruses, worms, Trojan horses, spyware, and adware. Malware can take many forms and can be designed to accomplish a wide range of malicious tasks, from stealing sensitive information to taking control of a computer system.
In general, the terms “virus” and “malware” are often used interchangeably, but technically, a virus is a specific type of malware. All viruses are malware, but not all malware is a virus. To protect your computer system, it’s important to be aware of the different types of malware and to take steps to prevent infection. This includes installing antivirus software, avoiding suspicious emails and downloads, and keeping your operating system and software up to date.
Can I remove viruses from my hard drive manually?

Instead, it’s recommended to use antivirus software to detect and remove viruses from your hard drive. Antivirus software is designed to identify and remove viruses and other malware, and it can do so more effectively and safely than manual removal. If you do decide to attempt manual removal, be sure to back up your important files and data first and be careful not to delete any critical system files.
How do I prevent viruses from infecting my hard drive in the future?
To prevent viruses from infecting your hard drive in the future, it’s important to practice safe computing habits.
