To help protect yourself from rogue security software:
Install a firewall and keep it turned on.
Use automatic updating to keep your operating system and software up to date.
Install antivirus and antispyware software such as Microsoft Security Essentials and keep it updated. For links to other antivirus programs that work with Microsoft, see Microsoft Help and Support List of Antivirus Vendors.
If your antivirus software does not include antispyware software, you should install a separate antispyware program such as Windows Defender and keep it updated. (Windows Defender is available as a free download for Windows XP and is included in Windows Vista.)
Use caution when you click links in e-mail or on social networking Web sites.
Use a standard user account instead of an administrator account.
Familiarize yourself with common phishing scams.
If you think you might have rogue security software on your computer:
Scan your computer. Use your antivirus software or do a free scan with Windows Live safety scanner. The safety scanner checks for and removes viruses, eliminates junk on your hard drive, and improves your PC’s performance.
