Their behavior is similar to a drop of ink into a container full of water.    Infected Hard Drive                   9 Viruses can also outsmart anti virus tools by "hiding" in restricted areas such as System Restore or registry, system files or Java scripts. Therefore they are not easily detected by anti virus programs or Registry editors    Anti virus programs may not always work   10 Some viruses may remain on your hard drive even after anti-virus programs remove obvious viruses   Viruses still present                     11   The guaranteed removal method is by reformatting the hard drive then reinstalling the Operating System then reinstalling programs and tools OR      12   utilize AltE, the AltErnative to PC solutions.
