5. Run Antivirus Software and a Spyware Detection and Removal Tool
Updating your Windows software is just the first step in keeping your computer safe. Next, you’ll want to download and install antivirus software and keep it up to date. Your computer may have come with a free trial of antivirus software, but if you don’t renew your subscription, you won’t be protected from all the latest threats. If you don’t already have antivirus software, or if you’d like to get different antivirus software, check the Windows Marketplace Antivirus section for products that will work for you.
If your computer seems sluggish or if you begin to see lots of pop-up advertisements, even when you’re not surfing the Web, your computer may be infected with spyware, adware, or other unwanted software. Learn more about spyware and what it can do to your computer, then download the free antispyware program from Microsoft.
