It not only can, but does. According to a July/August 2008 article in Women's Health magazine written by Colleen Oakley, "'Every time the virus is transmitted, it undergoes small changes,' says Patricia Fast, chief medical officer at the International AIDS Vaccine Initiative (IAVI). This means that no two people are infected with exactly the same strain of HIV, making it nearly impossible to create a universal antidote" (98).

Yes, viruses can mutate to infect new species.

Yes, viruses evolve over time. They will usually mutate into a stronger virus. When viruses face something new that could stop them, they usually mutate.
The HIV virus is highly unstable, meaning that it does mutate quickly. That has been part of the dilemma in finding a cure, or even a vaccine against the virus.
vacicien are dead or inactivated viruses or bacteria that activate the human imunity and relase long life imunity again the patogen (sometimes month or years). Inactivated HIV or dead HIV particile it dosent activete the Imune response to make antibody again the virus.Using life viruses it make hard because of the potential infection with the viruses. As the virus reproduces, it can mutate with different strains emerging. A+
If you are talking about virus as in illnesses, then it is because they are immune to antibiotics and mutate. If you are talking about computer viruses they are hard to totally eliminate as they constantly mutate
The time it takes a virus to mutate varies depending on the virus. However, viruses mutate frequently so it is very difficult to completely eradicate a virus.
No medicinal cures, only your body's B and T-cells remembering and attacking the disease causing viruses the next time they show up... This poses a problem with viruses that mutate often as well as viruses like HIV that enter cells and reprogram the DNA inside the cells making them multiply with more and more bad copies of DNA...
