There are a lot of differences and you can write an entire book on the subject. But, I will keep it simple. Viruses are obligated intracellular parasites (OIP). Wow, that's a mouth full. What this means is that viruses infects individual cells. They penetrate in to the cell and causes damage from within. Most bacteria do not penetrate in to a cell, though there are exceptions. Since they infect differently, the human immune system has develop different ways to fight off the infections. It is common for bacteria to produce chemicals that are toxic and improves its ability to infect a host. Viruses are just strands of DNA or RNA which incorporates itself in to the host DNA.

A bacteria is different from a virus. A bacteria is a fully formed and functioning living organism, simply one single cell. A virus, on the other hand, has no organelles, no "living" structures of its own- merely DNA and the means to inject it into another cell. Virus DNA cannot replicate itself like living cells, it is necessary for it to invade other cells in order to replicate.

The virus enters the cell of the host and use the DNA (host's DNA) to make his required proteins. The bacteria bond with the cell, don't enter,

The infectious agent that causes the illness.
Viruses are different than bacteria. They do not respond to antibiotics, for one thing.
