These security features are also extended to include special banking Trojans: these exist to manipulate referrals, causing significant damage in some cases. This makes it much safer to shop online or to operate online banking. Using the tool also makes surfing the Internet much safer: websites that are infected with malicious code block the virus scanner before it is even called. This also works for gaps that are not yet known: The antivirus program checks how the malware behaves and whether their approach differs from normal programs. Thus, users have nothing to fear, even if vulnerabilities are exploited, which are tailored specifically to the software on their own computer. No software can ever be 100% secure - and G Data Antivirus keeps those vulnerabilities hidden. Since the Internet is the biggest gateway for malicious software of any kind, users protect themselves with this technology very effectively.Īs users buy G Data Antivirus, they also protect themselves from the vulnerabilities of other programs such as Adobe Flash, Microsoft Office, and similar applications. This also works for downloads: they do not get fully into the PC as soon as the antivirus scanner detects a threat. All others rely on the software's secure presets. Experienced users can then manually decide what to do with the file. As soon as a file being executed behaves suspiciously - for example, by starting processes in the background that have nothing to do with the actual file - they are stopped by the anti-virus software. To ensure reliable protection, G Data Antivirus works proactively. Users who buy G Data Antivirus will get the most out of it. A look at the emergence of new viruses shows that this technology is necessary: about every six seconds new malware appears on the Internet. These search both already known malware as well as completely new viruses or threats, which are limited only locally to the respective device. To ensure the high virus detection rates of the program, two virus scanners work in it. A loss of performance when using other applications is therefore not to be feared. The software is optimized for a low resource usage during its work and thus a high speed also with the background scan of important data. This means that it may take a while to download these files, and that you will need a fast PC to work with them.G Data Antivirus is an ideal antivirus solution for home users. High resolution files for large areas (countries) can be very large. A cell with a 30 seconds resolution is about 0.8 km2 at the equator and smaller at higher latitudes. The size in square meters varies with latitude. When the cell size is small (e.g., 30 seconds), resolution is high. The units are in (arc) degrees, minutes or seconds. The resolution is the size of each grid cell expressed as the length of one side of one (square) cell. For the other gridfiles, NODATA is only used for areas covered with water, except for the land cover grids, on which water is a separate class.Ī DBF (dBase file) is a dbase format database table. For these areas, the value is "NODATA" (indicating the absence of data for those cells). ( More info on format for developers).Ī gridfile with "country mask" indicates that the areas outside the selected country are masked out. From DIVA-GIS they can be exported to a number of other grid formats including IDRISI and Arc or to shapefiles. Shapefiles contain a single class of "vector" data such as points, lines, or polygons. It can be imported to most other GIS programs. This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS, and many other programs. Grid (raster) data are stored as DIVA gridfilesĮach "shapefile" consist of at least three actual files. Vector data are stored as ESRI shapefiles You can use programs such as 7-zip, PKZIP or StuffIt to decompress the files. The files have been compressed and grouped in ZIP files. National Imagery and Mapping Agency's (NIMA) database of foreign geographic feature names They can also be used to map localities, however you can download more recent files from NIMA The files should be placed in the \gazet directory. The files you can download here are for use in DIVA for automatic georeferencing (to assign coordinates to places).
