Пора уже выбрасывать Нортон и Маккафи. Их суппорты стинк, жрут ресурсы, замедляют все процессы, отказались от фаярвол.

Вот, что советует СНЕТ.

Trend Micro PC-cillin Internet Security 2005
Last year, I awarded PC-cillin our 2004 Editors' Choice because Trend Micro included a firewall with its antivirus app and offered free technical support. I thought that was as good as it gets. Well, it just got even better.

This year's version of Trend Micro PC-cillin Internet Security, CNET's Editors' Choice for 2005, includes an antivirus scanner, a firewall, antispam and antispyware capabilities, and parental controls--and that's only the start. Trend Micro also added a wireless network monitor this year, allowing you to enable or deny wireless access for others to your network. And Trend made it possible to apply one set of security configuration rules across every computer on your home network (other apps require you to copy the configurations from machine to machine). Here's the kicker: PC-cillin costs the same as Norton's or McAfee's antivirus apps. It also makes barely a dent in your system resources; when it's scanning, you'll hardly notice PC-cillin.
