Extremely slow connection using SecureLine VPN

Hello all,
I bought a license to SecureLine VPN because my wireless is public and I’d like the maximum amount of protection available.

Unfortunately, every time I start this program, my computer monumentally slows down and stops being able to load any page. It literally shuts everything down. Instead of being capable of using my computer as needed with this program, I have to turn the VPN completely off to get anything done.

I know nothing about fancy computer stuff, I just know I spent hard-earned money to buy this program that appears to be a dud. Please help!

I have already tried that and it changed nothing. I seem to be having the same issue as this person: https://forum.avast.com/index.php?topic=178198.0

Unfortunately, I already repaired the program and it did nothing. I submitted a ticket today. Not impressed with this program as of yet as I have to turn it off every time I want to go online. Kinda defeats the purpose.

Thanks for your attempted help!
