A normal antivirus compare a suspect file to a signature database is updated regularly. These are generated by the development team of the virus, which ensures - in theory - that malicious code is found. It is a manual process and very expensive.
This year the virus appeared new concept. Do not use databases, but are directly connected to the network of the user community to share and view the signatures of harmful files. What is the advantage of this architecture versus traditional?
The contribution of thousands of users simultaneously makes threats are detected and eradicated at a rate much higher. Connected to each other, millions of computers make up a genuine "collective intelligence". Still in development, the virus of this type represent a genuine revolution.
A hive-mind viruses
To understand how this type of virus must first define the concept of " Cloud , "a word that has become very popular in recent years. The Cloud is a metaphor for the Internet: the user exceeds the limits of their own computer to carry out actions in a decentralized environment. Cloud applications are, for example, P2P networks like BitTorrent or Gnutella.Un esquema de la Nube
A virus that works through the cloud is just a set of removal tools and quarantine. Without Internet access, these programs are useless, since to identify a virus must submit the fingerprint detected a network of computers that share similar information.
If a computer detects a dangerous program, the virus will propagate the sample through the cloud in a similar way as would a P2P program. Within minutes, all other users will be able to eradicate the new malware from their computers. Compared to the time it takes a classic antivirus update, which needs very little cloud.
Panda Cloud, and HouseCall Immunet
Three antivirus are those who use this technology exclusively. This is Cloud Panda Antivirus , Immunet Protect and Trend Micro HouseCall . Panda Antivirus Cloud was the first to appear, and is - so far - the most stable and solid, apart from being the only translated into Spanish. Surprises with its minimalist look and accessible, a trait shared by its competitors.
La interfaz de Panda Cloud Antivirus
With quarantine notices in the taskbar and a system for silent management of threats, Panda Antivirus Cloud could be compared to a missile "fire-and-forget." Left alone, automatically takes care to remove any suspicious files.
La ventana de opciones de Immunet Protect
Protect Immunet is very similar. Created by a former developer of Symantec (Norton Antivirus authors) Immunet also provides real-time protection and scans a user's request. Compared to Cloud, we were disappointed by its more slowly and the occasional connection problems.
Trend Micro HouseCall examinando un equipo
Trend Micro HouseCall 7.0 is a product that uses the Smart Protection Network. Unlike Panda and Immunet Cloud, HouseCall is not a resident virus, but a customer looking for viruses on demand. It is ideal for cleaning an infected system if necessary.
Does the antivirus for Grandma?
The strengths of the virus in the cloud are evident: very short response times, minimum use of resources and ease of use. They are perfect for those users who do not want to complicate your life making decisions about a suspicious file. But not all joy.
Un aviso de Panda Cloud AV A warning - very little information - Panda Cloud
Testing them on a daily basis, this virus has shown a false positive rate higher than normal. It is unclear to what extent the collective intelligence calibrates and corrects itself. An alarm of suspicious files can be spread without filters by an extensive network but who verifies whether the danger is groundless?
Panda en modo offline
Another major problem is the reliance on the Internet. A virus that connects to the cloud requires a permanent connection to the Net Right, it's the place that comes from the vast majority of viruses, but what if we find malware on computers isolated? The loss of connectivity makes these antivirus become almost useless.
Finally, the question of simplicity. Panda Cloud, by taking the most popular example is extremely intuitive, but the degree of control offered is minimal. In his defense, we would argue that the options under the limited range of moves available, but not entirely share that view.
The virus in the Cloud have very quick reflexes, but his sight is very short. "It makes more sense to integrate their potential in a traditional antivirus or should go their own way? I give the floor.
