So this problem has been happening for a while but I have dealt with it by finding little bypasses by downloading things and such. The problem is I can't install almost any programs on my PC. Curse client, Breaking point, WS Installer, and random files from google chrome I cant download. The downloads from google chrome I can fix by either using a proxy or using firefox. The programs I try to install things from I seem to cant get a good fix for though. They will start up with my normal 6mbs speed but then drop to 70kbs or stop in all. I have tried to find this problem multiple times when it first happened and even wiped my computer with no luck and it is starting to annoy me. If I do not turn off smart firewall/antivirus auto protect on Norton and run in admin mode it almost never works at all as in it will not start with a down-speed and it will just sit. Please send any help my way!
