SpySweeper (by WebRoot) It is extremely important to do regular system maintenance to ensure that your system runs properly. There are certain programs that come with Windows that you should run regularly to clean out the hard drive and organize files, especially if you have installed and/or uninstalled software. You should also be aware that dust is an enemy of your computer, vacume regularly behind the case / tower and even vacume the areas where there are the cooling fans and power supply fans vent. Be sure to have the current virus definitions installed and have the "automatic updates" activated to be sure that your system is always up to date.

Run the Anti-Virus scan weekly to be sure your system is clean.

We recommend that you run at least 2 different Anti-Spyware programs update them regularly, be sure to have them running in the background so your system is constantly protected.
