I used Microsoft Security Essentials to remove the trojan dropper from the system but now I don't have any internet access. An expert told me to use Avast! to clean my system because of it's powerful Boot Scan. Nothing was found. I have connections with my wireless laptop so it isn't the router. I have also updated the Wireless Adapter driver and no progress. Please help with this issue. I'm unsure how this got on my computer because I had Microsoft Security at the time. I suspect that it has dropped it's payload. The network driver is / was infected.
