Wireless Network Adapter Corrupted

My laptop is an Acer Aspire 5534 operating Windows 7. I never had any issues connecting wireless to the internet until recently. My laptop had adware, which McAfee wouldn't remove, so I never stressed too much about it since it seemed harmless although it was sometimes annoying. My McAfee was a valid and up-to-date subscription. This continued for a while without any further harm until the other night, I noticed a few new icons on my desktop. So I tried running a virus scan to see if anything would be detected. When I opened McAfee, the "Real Scan" was disabled and preventing me from running a scan. And every time I tried enabling it, I would receive an error message and it would immediately disable again. So I assumed whatever virus I had was affecting my anti-virus. So I pressed the Wifi button on my laptop to turn the network off to be safe and tried running another scan but failed. I could still turn my wifi on and off without a problem. I still couldn't run a virus scan. So I restarted my pc on "Safe Mode with Networking" and managed to run a virus scan that finished with no threats.
Once I restarted my computer on normal, my wireless internet access icon on the bottom-right corner had a red X over it and no connections were being detected. Additionally the troubleshooter and/or diagnose options are corrupted and are giving me errors. I've tried disabling it and enabling it, uninstalling the driver, system restore, removing McAfee in case it was preventing the network from starting, I unchecked the power save option, tried updating the driver and it says it's updated. I feel like I've exhausted all my options. I am able to use my local connection with ethernet, please help. Thank you.
PS. The wireless adapter is an Atheros AR5B93.
