Before removing a virus using manual or automatic techniques, you should always do what in a Windows 7 environment?
Explanation
Answer: A - Before removing a virus using manual or automatic techniques, you should always disable System Restore.
Key Takeaway: A virus can hide out in the system restore image, re-infecting a cleaned machine, thus undoing all of your hard work removing the virus. To prevent this from happening, it is always recommended you disable system restore before removing a virus. Although you will probably boot into Safe Mode for virus removal, it is not always necessary-and not required like disabling system restore is. You do not need to disable automatic scanning or purge the quarantine while removing a virus.
