Under some circumstances, one may have his/her computer infected with virus without knowing it, especially if the virus is Fud (Fully undetectable), then it naturally means that no anti-virus can detect it.
However, the good news is that viruses can't stay Fud for long.
There is no single anti-virus schedule which is designed to eliminate all types of viruses that have been ever made. As Anti-virus is all the time one step behind virus, it is of no surprise that any new Anti-Virus schedule is developed only after a new Virus is found. However, as pre-caution, please oftentimes check your anti-virus schedule to make sure it is working as the newest virus may disable your anti-virus schedule without you knowing it!
