Wifi much slower after security software download I recently downloaded a vpn and security software (Avast security and windscribe vpn), but my wifi dropped significantly from about 150 mb/s to ~50 mb/s, sometimes much slower. 

Even after I deleted the two softwares, my wifi is still at about 50. What can I do to make it go back to normal speeds? I initially thought it had something to do with the mac firewall, but I'm not so sure. 
Thanks

UPDATE

never mind, the problem seemed to fix itself somehow. wifi is now back to normal and full functioning
Uninstall both would be my recommendation. 


a vpn can send all traffic elsewhere so that has to be slower than letting you unfettered access to sites by the fastest route. 
Mac security software generally opens you up to more vulnerabilities then they patch and slow you down as well.
