It depends on the effectiveness of your antiviral program (if you have one). Viruses can go days, months, even years undetected on a computer. The only way to get rid of it would be through an antivirus program. However if the virus' function is to annoy the user than it will consequentially reveal itself to you anyway. If you do not have an anitvirus program I recommend you download one immediately. So long as you are connected to the internet, you are at risk of getting a virus or some other form of malicious software.
There are no real "Helpful Viruses". Viruses are viruses. They make things go wrong with your computer.

Chlamydia can go undetected for years. Chances of getting chlamydia from someone who's infected are about 40-60% for each episode of vaginal sex.

A computer virus can get into your computer if you go onto a harmful website, EG some porn sites

some viruses use the host computer's email to spread, but normally you can't go to the starter adress.
