File Infector Viruses

File infector viruses attach themselves to executable files and spread when the infected file is run.

These viruses can corrupt or delete files, making them unusable.

Common symptoms include slow performance, frequent crashes, and unexpected error messages.

Macro Viruses

Macro viruses target applications that use macros, such as Microsoft Word and Excel.

They spread through infected documents and can execute malicious code when the document is opened.

Macro viruses can cause data loss, unauthorized access, and other security issues.

Boot Sector Viruses

Boot sector viruses infect the master boot record (MBR) of a hard drive, making them difficult to remove.

They spread through infected bootable media, such as USB drives and floppy disks.

Boot sector viruses can prevent your computer from starting properly and cause data corruption.

Polymorphic Viruses

Polymorphic viruses change their code each time they infect a new file, making them harder to detect.

They can evade traditional antivirus software and cause significant damage to your system.

Polymorphic viruses can corrupt files, steal data, and spread rapidly.

Resident Viruses

Resident viruses embed themselves in a computer's memory, allowing them to infect other files and programs.

They can remain active even after the original infected file is deleted.

Resident viruses can cause system instability, data loss, and unauthorized access.

Conclusion

Understanding the different types of computer viruses is crucial for protecting your devices and data.

By recognizing the symptoms and knowing how viruses spread, you can take steps to prevent infections.

Consider using reputable antivirus software and practicing safe browsing habits to keep your devices secure.
