I had Spectrum’s GIG internet installed yesterday (technically 940mbps top speed). When the technician ran his speed test via his meter, he was getting 930 down. I then ran a speed test using http://speedtest.googlefiber.net/. I was only hitting 200-300 down. After spending last night and this morning tinkering with settings, I found that the Web Shield within Avast was slowing down my speed. I turned off Web Shield completely, and I’m hitting 930 down as expected. I turn the Web Shield back on and I’m back at 200-300 down. With the Web Shield on, I also tried unchecking every setting box (within the Web Shield settings), and still was hitting no more than 300 down. I turn Web Shield back off, and I’m back at the 930mbps down.
The meter the technician was using was clocking at the 930mbps. On my actual PC, with Web Shield on it was clocking at 200-300mbps. With Web Shield off, it was clocking in at 930mbps.
