Como evitar los virus informáticos v1
El computador es una herramienta que hace lo que le decimos, todavia no es autonomo :-) Siendo asi :-)
Soy responsable de usalo adecuadamente y debo tener CONCIENCIA de la informacion que recibo :-)
Consejos para evitar los virus informáticos
Verifica, antes de abrir, cada nuevo mensaje de correo electrónico recibido
Para prevenir esto, lo mejor es verificar los mensajes inesperados o que provengan de una fuente poco habitual. Un indicativo de posible virus es la existencia en el asunto del mensaje de palabras en un idioma diferente al utilizado normalmente por el remitente.
Evita la descarga de programas de lugares no seguros en Internet
Rechaza archivos que no hayas solicitado cuando estés en chats o grupos de noticias (news)
Ambos sistemas, además de permitir la comunicación con otras personas, también facilitan la transferencia de archivos. Aquí es donde hay que tener especial cuidado y aceptar sólo lo que llegue de un remitente conocido y de confianza.
Retira los disquetes de las disqueteras, CD's o DVD's, incluso las memorias USB al apagar o reiniciar el ordenador
Por si se nos olvida hacerlo, es conveniente contar con un antivirus capaz de comprobar en tales circunstancias la existencia de disquetes infectados.
Realiza periódicamente copias de seguridad

Monitores de red Open Source
Hay dejo varias fuentes, abajo relacionadas :-)
http://www.cacti.net/
About Cacti
Cacti is a complete network graphing solution designed to harness the power of RRDTool's data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices.
Icinga
Icinga is an offshoot
of Nagios that is currently being rebuilt anew. It offers a thorough
monitoring and alerting framework that’s designed to be as open and
extensible as Nagios is, but with several different Web UI options.
Icinga 1 is closely related to Nagios, while Icinga 2 is the rewrite.
Both versions are currently supported, and Nagios users can migrate to
Icinga 1 very easily.
NeDi
NeDi may not be as well
known as some of the others, but it’s a great solution for tracking
devices across a network. It continuously walks through a network
infrastructure and catalogs devices, keeping track of everything it
discovers. It can provide the current location of any device, as well as
a history.
NeDi can be used to locate stolen or lost devices by alerting you if they reappear on the network. It can even display all known and discovered connections on a map, showing how every network interconnect is laid out, down to the physical port level.

Observium
Observium combines
system and network monitoring with performance trending. It uses both
static and auto discovery to identify servers and network devices,
leverages a variety of monitoring methods, and can be configured to
track just about any available metric. The Web UI is very clean, well
thought out, and easy to navigate.As shown, Observium can also display the physical location of monitored devices on a geographical map. Note too the heads-up panels showing active alarms and device counts.
Zabbix
Zabbix monitors servers
and networks with an extensive array of tools. There are Zabbix agents
for most operating systems, or you can use passive or external checks,
including SNMP to monitor hosts and network devices. You'll also find
extensive alerting and notification facilities, and a highly
customizable Web UI that can be adapted to a variety of heads-up
displays. In addition, Zabbix has specific tools that monitor Web
application stacks and virtualization hypervisors.
Zabbix can also produce logical interconnection diagrams detailing how certain monitored objects are interconnected. These maps are customizable, and maps can be created for groups of monitored devices and hosts.

Finding the latter for free, when it works well and meets your event planning needs, can save you precious dollars and also from using a few other four-letter words.
Here’s our list of the top open source and free event management software out there:
In its free version, this platform creates event registration forms. For one user, it includes five forms, with up to 10 fields in each. You are also limited to collecting 100 submissions each month.
To get payment integration, you’ll have to upgrade to the Platinum or Diamond versions.
The good news is 123ContactForm integrates with WordPress and a number of other publishing platforms, as well as Facebook, Twitter and Hootsuite.
Anyvite lets you create event invitations, to be sent by email or posted publically on a webpage. They can be personalized with your own image, or you can choose from pre-made designs. Once they’re sent, you can message guests based on their RSVP and add an Anyvite widget to your site.
Ticketing and payment collection, however, incur a separate fee of $0.99 plus 2.5% of the ticket price, with card processing fees on top of that.
The free edition of Event Track is made to work with the free online event registration platform Jolly Events.
With Jolly Events, you can register attendees online on a customized registration form, send invitations, and send registration confirmation emails with barcodes. Then you can export your guest data for Event Track, which lets you register attendees on-site, register them for specific sessions of an event, print nametags, and scan barcodes to verify them.
Be wary, though: the free edition is “as is.” Jolly Events does not offer any warranty, or email or phone support for this product.
Event management on the EB Basic level is completely free. It’s robust for a free version, and includes a wide range of features, including event registration, an event page, and up to 500 email invitations.
Plus, you have options for collecting payments, which can go directly into your Paypal account. You’ll also be able to track progress and produce reports.
To get automated invoice and online payments, customize your event page’s look and remove ads, or offer an offline payment option, you’ll have to upgrade to the premium version, which has a 2% per ticket fee (which can be added to the ticket price).
If all you need is an invitation and RSVP system, the free version of Evite will fit the bill. The ad-supported option has a limit of 750 invitations, with a large selection of designs.
The premium version (price varies based on number of guests) allows you to customize invitations.
Specifically geared to planning a wedding, Seating Arrangement does more than just manage table space. It will be useful to any planner working on a banquet or dinner event.
You can use it to manage the guest list and menu options, sort guests by preferences like age or social group, track RSVPs, and print place cards. Its web-based design lets you work on your event from multiple locations.
If you are willing to host your own server, provide your own support for your maintenance issues, and abide by the license, OpenConf Community Edition is free for download and use.
Unfortunately the software does not cover the more advanced and new aspects of event management software, such as social media integration and mobile app use, as well as key features such as ticketing and vendor management. So, you take what you can get when it comes to OpenConf.
