Alright. Kind of a dead thread now but Spectrum sent a tech over to look into our issues and he said that there's too much network usage for the package we have. We're on a 10/1 package and have too many devices running and it's causing some of them to drop out when usage is heaviest. Essentially we are hitting the maximum our connection will allow. All the other advice will be taken into consideration but for now we are deciding if it is viable to upgrade to a higher package first to see if our issues subside. If not, we will try other things but this will be the first step.

It should be fine to remove anything not related to a hardware component on the machine. 
 
Realistically, you could probably just fresh install Windows on there and then install only the drivers needed to ensure all the hardware works. All of the software included by default is in the recovery partition, and also presumably from the Dell support site, so if you remove something you may find useful it's always going to be possible to reinstall it later.

I recommend Windows Defender and Malwarebytes too, not AVG....
