Gore, are you still pretending to be a technician? AVG? Worst heuristic capabilities on the market, application incompatabilities, and weak removal capabilities.

BrokenCrow, do a repair installation first. Don't **** with NTFS conversions until it's done by the live system. You risk ****ing up some of the metadata and file ownerships. Once the core files are replaced, boot the machine and run MalwareBytes to remove any critters. Fix the LSPs and any winsock issues, and then convert the drives to NTFS.
