I have an old HCL Me laptop with i5 3rd gen. I don't use it very often.\nRecently I upgraded the ram to 8gb from 4gb. During this time I somehow got a virus the TrojanDownloader:JS/Fakepack.\nSo for safety reasons I removed the WIFI adapter (hardware). I have successfully removed the virus (it doesn't constantly shut down now)\n\nI tested the laptop without the adapter for a few days. Today I reconnected the same adapter back. Now the WiFi is not switching on.\nI tried Uninstalling and Reinstalling Driver.\nDisable/Enable.\nReconnecting Adapter.\n\nIt's still not switching on. I can't even see available networks.\n\nI'm pretty sure it's a software issue. Let me know what I can do to make this work.\n\nThanks in advance.
