I got to back chrono up I know tons of ways viruses can hide in windows. Here's a few.
Setting visibility to hidden.
Using file names that look like legitimate software.
editing the registry to disable 'show hidden folders'.
Registering the virus as a service.
Software level root kit using api hooks to modify the result of system calls.
Hardware level root kit changing the system itself.
.dll injection to force another process to run your code.
The entire window messaging system is insecure you can delete everything displayed in the process list of Task manager for example.
some of these techniques will make a virus completely invisible so don't bash
