According to statistics, new varieties of malware arise daily. And even more often! It is possible that at the very moment when you read these lines, a new type of malware is registered on the global network . We will not give an assessment to individuals who have turned a storehouse of human wisdom into a potentially dangerous place - we will leave it to psychologists.
Be that as it may, at the present time you should not connect to the
global Internet without an antivirus program.
Computer software protection
As you know, where there is demand, there supply is not long in coming. Many companies offer various solutions to protect data from computer viruses. Some of them are very successful, such as software products from Kaspersky Lab, NOD32 from Eset, etc. These solutions are very popular among users. Currently, complex software systems, the so-called Internet Security group, are especially relevant. They are in the line of each manufacturer, however, they can be called differently. For example, Dr.Web has Security Space, and NOD32 has Smart Security. However, protection works properly only if the program has the ability to be updated - from any source to receive updated versions of its own files and virus databases. Otherwise, a situation may arise when a new malicious code turns out to be invisible to the anti-virus detection algorithms. Since the topic is too extensive, today we will consider why Kaspersky Anti-Virus is not updated.
Little-known nuances
If Kaspersky is not updated, do not panic - it will always succeed. Usually the cause is easily fixed even without contacting customer support. Well, we recommend rolling up your sleeves and ... first carefully read what to do if Kaspersky is not updated.
One of the reasons is the actions of the virus that made changes to the hosts system file. In Windows, you can access it by following the path c: \ Windows \ System32 \ drivers \ etc \. By making changes to its structure (edited by notepad), you can redefine the addresses of Internet resources or block access to antivirus servers. Result - Kaspersky is not updated. We recommend that you familiarize yourself with the normal contents of hosts (for example, on Wikipedia) and edit it if necessary.
The next possible reason that Kaspersky is not updating is an unstable Internet connection.
In this case, the process is simply interrupted at some stage (for example, upon reaching 70%). The solution is simple: you should enable the update again. It is also worth noting that sometimes the indicator freezes at around 99% and nothing happens for a long time (sometimes up to five minutes). In this case, wait a little longer.
If Kaspersky is not updated, it is possible the work through a proxy is specified in the settings. It is necessary to press the "Proxy server" button in the parameters of the update source and register the correct data (if any) or disable this mechanism (if not used).
Another common reason is key expiration. Such an antivirus is not updated.
