Recently had an issue where I got infected causing my internet settings to be changed so I couldn't access the internet via IE. It was one of those phony "security issues." It wanted me to purchase a anitspyware program and all. I could receive my email, download bank info and what not. Ran my AVG 9.0 it found and isolated 3 trojan horse virus. I was able to find that the LAN settings were changed and I switched them back, just by unchecking a checked box which is normally not checked. The questions is, is there something else I need to do to make sure I'm virus/malware free? I use malwarebytes frequently to scan my computer for malware. Ran it recently, a full scan , and it found nothing. Also use ATF cleaner frequently.
