Open the Quick Heal program on your computer by looking for the 'Q' logo on the very bottom right hand corner of your screen, near the time, date and volume or it might be in the hidden icons. When you find the 'Q' double click on it to open the program.
Once you have opened the Quick Heal program => Click on 'HELP' (small heading at the top of the page) and then scroll down and click on 'ABOUT'. On the bottom of the next page look for the heading 'RENEW NOW' and click on it. On the next page (which is the Security Registration Page) select the option 'I have renewal code with me' and key in one of your Renewal Code. Then follow the prompts until you come to 'FINISH'.
