The fully automated update process will keep your computer protected at all times. Components include AVG Email Scanner, which checks your incoming and outgoing e_mail for viruses; AVG Resident Shield, which checks for viruses as files are opened, executed, and saved, and will prevent you from opening or running an infected file; and AVG Virus Vault, a place where infected files are isolated so they cannot cause damage to your system. Version 7.5 includes improved virus detection based on better heuristics and NTFS data stream scanning, smaller installation and update files, and an improved user interface.
