Do you mean transforming viruses perhaps?
Chromosomal damage often results in a transformation of the cell towards becoming cancerous, and this can occur through viral actions.

Hope this is some help, if not e-mail me.
Oh, and to the answerer above I say: If you are going to copy information straight from a website, please have the decency to tell us which.

1. Most commonly viral damage to the host cell is manifested as cell lysis mediated by one or more of four types of allergic reactions.

2. Type II allergic reactions involving IgG and/or IgM are the major mechanism of viral-induced cell lysis.

3. Type IV allergic reactions not involving antibody are the second most common mechanism of viral-induced cell lysis.

4. A few species of viruses produce viral components which are toxic to the human host cell much like some products of bacteria.

5. Certain species of viruses have the ability to transform a benign cell to a malignant cell via integration of the viral nucleic acid into the human chromosome.

6. Selected species of virus have the ability to alter human immune responses (humoral and cellular) via alteration of immune cell metabolism or immune cell lysis.

7. Some species of viruses "turn on" or activate host cell genes to overproduce the gene product. This product can be cytotoxic in high concentrations.

8. A great number of viral species induce cytoplasmic and/or nuclear changes in their host cells which can be used by the pathologist in diagnosing viral infectious diseases.
