AVG Free

• 1). Download and install AVG Anti-Virus Free (see "Resources" below). AVG Anti-Virus Free is an extremely powerful virus scanner.
  
  
• 2). Install the AVG watchdog toolbar. This is optional, but it helps to keep your Internet browsing safer.
  
  
• 3). Set up a maintenance schedule when prompted by the install wizard. Schedule weekly scans to run when you are away from your computer. This will automate virus scans so you don't have to manually do it every week. Finish the installation. If you would like to run a scan manually; run AVG Free, and from the opening menu, select "Scan Now."
  
  

Glary Utilities

• 1). Download and install Glary Utilities (see "Resources" below). Glary Utilities is a freeware program designed to clean up and optimize your PC. Its simple-to-navigate menus and "one-click-maintenance" options make this program a must-have.
  
  
• 2). Run Glary Utilities when the installation is complete. From the main menu, select the 1-Click Maintenance tab. A list with check boxes will appear. Check all of the boxes and click the "Scan for Issues" button.
  
  
• 3). Click "Repair Problems" when Glary Utilities is finished scanning your computer.
  
  

Malwarebytes' Anti-Malware

• 1). Download and install Malwarebytes' Anti-Malware (see "Resources" below). This program will remove spyware and malware from your computer quickly and effectively. Malwarebytes, however, does not have a scheduler or real-time protection in the freeware version.
  
  
• 2). Begin the initial scan of your hard drive once you have finished the installation. This can take up to an hour and a half. When the scan is complete, repair the problems Malwarebytes has detected.
  
  
• 3). After the initial scan, you can select quick scan the next time you run the program. This takes about eight minutes to complete and is very thorough.
