Computer freezes periodically while typing for at least 15-30 seconds

I am not sure if the full protection from AVG is causing the issue of freezing all the time where I can not type anything and then after 20-30 seconds I can start again.  Its while working in an appraisal software and I do have Windows 7 older Dell Computer.
Anyone know what might be causing this issue?
Thanks,
K

Hello Keith,

I am sorry to hear that. Please open the control panel and check if you see two entries if AVG Internet Security/protection on your computer. If so, please uninstall the older version using AVG remover tool mentioned in this article https://support.avg.com/SupportArticleView?l=en&urlName=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product.
