My Anti-Virus is AVG 2015 Free

So lately i've been using CS:GO Mods/Hacks, and downloading them and using them all from this Website (I'm not trying to point fingers, or say this website is virus infected). I am always connected to our Private TeamSpeak Server (My Clan/Group) of me and my friends, so I know how much ping, packet loss, in and out bytes, etc. that I have, plus to talk to my friends while gaming. Anyways for the past few weeks I have been having massive Lag spikes (100-5K Ping) to our TeamSpeak Server (Average of 45 Ping).

This is an Image I recently captured as my ping was rising


Any suggestions or ideas of what could be the problem.

P.S. My internet isn't the greatest, plus I live with 5 other people, 2 of which are using Xbox/Ps3 and stuff, and all of us have Phones using WiFi. But recently this has really acted up and is getting on my nerves when in CS:GO Comp match having 100+ ping and being frozen.
