A couple of days ago AVG AntiVirus detected an infection (Trojan.Agent/Gen-Kryptik) and, on my request, quarentined it but also located two additional files that were involved (NetBT - I forget the extensions). I rebooted and did not have any Internet access. I scanned my system with the following programs with a reboot between each for good measure. SuperAntiSpyware (Quick scan and Critial Points scan), Spybot Search and Destroy and a full scan by AVG AntiVirus. I used these programs because I had updated them on Friday for my usual 'end of the week scan'. No further infections were identified. However I still do not have an Internet connection. I do have connection within my home network (computer to wireless computer) and my wireless computer can access the Internet so the problem is definitely related only to the computer that was infected. I also tried the Startup Fix located on the recovery disc with a response that there were some corrupt files that could not be fixed. There was no indication of what these files were. I'm running Windows Vista Home Premium Service Pack 2. Any assistance would be helpful.
