Stop automatic updates

Hello A,
We regret for the inconvenience caused. We suggest you to follow these steps: Open AVG->Options->Advanced settings->Schedule-> Definition update schedule - in the right panel, uncheck the setting "run when computer starts up if task has been missed". Please note that only critical updates are being downloaded and installed automatically to make sure that your computer is not vulnerable to the very latest threats and so your PC is more secured and safe. Thank you.

Can I be alerted to new updates rather than have them downloaded automatically on start up as this slows down my computer?

Hello A I,

If you untick the "Enable this task" check box then you couldn't make any changes which means that you have completed disabled the Schedule update task for the updates. If you tick on the check box you can setup the date and time for the definition updates to get scheduled. Please have a look at this guide http://files-download.avg.com/doc/AVG_Free/avg_free_uma_en_ltst_22.pdf and search for Schedule updates. You can find sufficient information regarding the updates.
Please feel free to contact us if you need any assistance.
