What are computer viruses?
Computer viruses are malicious software programs that can self-replicate and spread internally to your computer, causing damage to your data.
It is called viruses because just like a virus spreads into the human body, computer viruses spread into the computer. As a virus can harm us, the malware can harm all the data in our device, thus compromising it. The computer's resources will be hijacked and the malicious code of the virus can erase, steal, or corrupt the sensitive data.
How do computer viruses spread?
Computer viruses spread through various methods, primarily through:
1. Email Attachments:
Viruses can be disguised as attachments in emails. When users download and open these attachments, the virus infects their computer.
2. Infected Files:
Downloading files from untrustworthy sources, such as pirated software or compromised websites, can introduce viruses to your system.
3. Removable Media:
Viruses can spread through USB drives, external hard drives, or other removable media if they are connected to an infected computer and then to another device.
4. Networks:
Viruses can exploit vulnerabilities in network protocols to spread from one computer to another within the same network.
5. Downloads:
Visiting malicious websites or clicking on pop-up ads can trigger downloads of infected files without your knowledge.
6. File Sharing:
P2P file-sharing networks can inadvertently spread viruses if infected files are shared among users.
7. Drive-by Downloads:
Some websites can automatically download viruses to your computer without your consent, simply by visiting the site.
What are the signs that my computer might be affected by a virus?
Just like our body starts sending us signals when we get into contact with a virus or a person being a carrier, similarly, our computer also starts sending us signs of possible exposure to a virus. Here are some common signs:
Performance: if you notice that your computer is performing slower than usual, it might be because a virus is consuming its resources.
Crashes and Freezes: Frequent crashes or freezes may also be a sign of a virus. However, this might be when you are performing simple tasks.
Unexpected Pop-ups: Pop-up windows appearing even when you're not browsing the internet can be a sign of adware or a virus.
Unusual Hard Drive Activity: If your hard drive is constantly active even when you're not using your computer, it could be due to a virus.
Unexplained Data Loss: Missing files or data that you didn't delete could be a result of a virus.
Changed Homepage or Search Engine: If your web browser's homepage or default search engine has changed without your permission, it could be due to a browser hijacking virus.
Disabled Security Features: If your antivirus or firewall has been disabled without your knowledge, it could be a sign of a virus.
Unexpected Emails Sent from Your Account: If your friends or contacts report receiving strange emails from your account, it could be a sign of a virus sending spam.
How do I remove the virus from my PC?
1. Update Your Antivirus Software:
It's essential to keep your antivirus software up to date with the latest virus definitions. These updates include information about new viruses and how to detect and remove them.
2. Run a Full System Scan:
A full system scan will thoroughly check your entire computer, including all files and directories, for any viruses or malware. This scan may take some time, depending on the size of your hard drive and the number of files on your computer.
3. Quarantine or Delete Infected Files:
When the scan is complete, your antivirus software will display a list of infected files. You can choose to quarantine these files, which isolates them from the rest of your system, or delete them entirely. Quarantining is usually safer, as it allows you to restore files if needed.
4. Restart Your Computer:
After removing the infected files, restart your computer to complete the removal process. This helps ensure that any remaining traces of the virus are removed from memory.
5. Run Additional Scans:
To be thorough, consider running additional scans with other antivirus programs or anti-malware tools. Some viruses are more easily detected by one program than another, so using multiple tools can help ensure all threats are removed.
6. Update Your Operating System and Software:
Keeping your operating system and software up to date is crucial for security. Updates often include patches for known vulnerabilities that viruses and malware can exploit. Make sure to regularly check for updates and install them promptly.
7. Change Your Passwords:
If you suspect that your passwords may have been compromised, change them immediately. Choose strong, unique passwords for each account to prevent unauthorized access.
8. Backup Important Files:
Before removing viruses, it's a good idea to backup important files to an external hard drive or cloud storage service. This way, if something goes wrong during the removal process, you won't lose your valuable data.
