I have an old HCL Me laptop with i5 3rd gen. I don't use it very often.
Recently I upgraded the ram to 8gb from 4gb. During this time I somehow got a virus the TrojanDownloader:JS/Fakepack.
So for safety reasons I removed the WIFI adapter (hardware). I have successfully removed the virus (it doesn't constantly shut down now)

I tested the laptop without the adapter for a few days. Today I reconnected the same adapter back. Now the WiFi is not switching on.
I tried Uninstalling and Reinstalling Driver.
Disable/Enable.
Reconnecting Adapter.

It's still not switching on. I can't even see available networks.

I'm pretty sure it's a software issue. Let me know what I can do to make this work.

Thanks in advance.
