What is a set of patterns?
The pattern file is a computer file used to capture viruses and often works in a tandem with a larger antivirus program. This type of file usually has a small and basic virus definition, so it can help identify viruses, but rarely has a full definition. To help find viruses, it copies a small amount of information from the file, and if it tests positive as a virus, it will transmit information to the antivirus program. Most patterns are made to work with only one or limited number of antivirus programs and there are few general patterns. This file does not have a complete definition of viruses, so it is much lighter, making it easier to brows through other files and information extraction.
When an antivirus program is installed, it will usually have a large virus library and contain a complete definition or code of each virus, so it knows how to identify malicious programs. A set of patterns usually does not have a complete definition. RATHER, contains partial definitions that allow it to identify potentiallyBut malicious files are not intended for the final decision on whether the set is dangerous.
To help scan the antivirus program, a set of patterns will float and copy information from the files found on the computer. Most files will be harmless and the pattern file will move to the next file. However, if extracted information is similar to a virus, then the pattern file will alert the attention of the antivirus program and the antivirus program will perform a thorough scan of the file.
Most patterns files are not general or installed on a computer. They are part of the antivirus program and most of them can only work with the same or similar antivirus program. Even if these files are installed on a computer, if there is no compatible antivirus program, a pivard can, then the patterns files will not be very good.
Even if you do not have the full definition of viruses and lack capableStop to destroy the viruses itself, may seem like an obstacle, which is to reduce the weight of the pattern set. This file is smaller, so it can easily scan other files without creating a large digital track. This also allows him to constantly float around other files without causing frequent lagging for users, while the antivirus program could cause delay if he was constantly scanning a computer.
