Guide to Virus Removal and Answering Exam Questions [CompTIA A+]
Importance: Virus removal is fundamental to computing as it keeps systems safe, secure and functioning optimally. Viruses can breach sensitive data, cause system crashes, slow performance, or even render a computer unusable. Hence, it's crucial to understand virus removal.
What is Virus Removal: Virus removal is the process of identifying, isolating, and eliminating viruses from a computer system. This includes scanning for viruses, removing any detected threats, and restoring any damage caused by the virus.
How It Works: Virus removal typically involves the use of antivirus software. Antivirus programs scan system files and directories for any malicious codes or activities. Once a potential virus is identified, the software either quarantines the virus or deletes it altogether. Following removal, the software also fixes any system changes made by the virus.
