Summarize the following:
This is not to be confused with a power strip. A surge protector will look like a bulky power strip. When your home receives a power spike, the surge protector takes this spike and pushes it away from the outlets and your computer.  Remember that even the best surge protectors will not protect against a direct lightning strike.  For ultimate protection, if you happen to be home, unplug the surge protector in the case of a threatening storm. Look for the following features:  If you regularly connect your computer to the internet, ensure the surge protector has a internet cable surge protector. Look for a surge protector that offers insurance to cover the loss of properly attached equipment.

Summary:
Use a surge protector. Make sure you're buying a good surge protector.
