Thank you everyone!!! Although it's not in my AQA spec, I was just curious on how viruses are killed. Thanks everyone and good luck to those who have the exam tomorrow!!
Viruses are not technically alive, as others have mentioned. They cannot reproduce on their own, and do not metabolise. They are at best biologically active bundles of DNA/RNA assorted proteins.
Your immune cells (B-cells) release anti-bodies which are specific for that given virus. Anti-bodies can be in different formations, and some of them help bundle viral particles up together.
This probably goes way beyond the scope of A-level Biology, but if you're interested i'll give a bit more information.
You have a special immune cell called a T cell. When these get going, they will go around telling other parts of your immune system to target the specific protein that is causing the immune response, in this case the virus. From here the B-cells are activated for this protein, and release the specific anti-bodies required (this is the humoral immune response). The T cells don't stop working however, some of them go around with special receptors specific for that viruses proteins, and will kill any of your own cells which are showing signs of being victim to that viruses invasion (viral proteins on the cell surface). This causes temporary destruction of tissue, but it prevents the viral infection from spreading/multiplying. This is the cell-mediated immune response.
Like I said, this is quite an in-depth topic, and I've barely even glossed over the details. If it's something you're interested in, then it would be covered in the second/third years of university course,
