In brief: Depends on the virus
That depends on which virus you're asking about.
The typical common cold last 3-7 days. Influenza (the "flu") is similar, but sometimes lasts longer. Viral gastroenteritis sometimes just lasts for a day or two. There are other viral infections that never "run their course." for example, herpes and HIV are chronic infections that persist for life.
