Tips & Warnings
Remember to scan all files before opening them onto your computer. Do not share files among friends or download software from sources you don't know. These are the best ways to prevent acquiring viruses, including stealth viruses.
Some viruses, like Monkey, must be in memory in order to mount the infected drive. If your virus scanner is updated, it should be able to remove these viruses.
