The weakest link in the data security system and the computer itself is always a human being. It's him who enters suspicious websites, he creates weak passwords and it's him who writes them down on a piece of paper stuck to the computer case.
You can, of course, train and raise awareness of safety issues, but there is always someone in the company who does not follow the recommendations anyway. The only solution to this situation is special software, which will protect the user against his own incompetence and ignorance.
The most popular computer protection programs are antivirus, which are applications that fight against various types of malware. There are several solid options on the market, some of which are even free under certain conditions. Their effectiveness is relatively satisfactory, and the only drawback of the solution may be a reduction in system performance, which on very old office computers may still be important today. For optimal security, the antivirus must be updated on an ongoing basis, it must work all the time, and periodically you must perform a manual full scan of the system.
The first pillar of security is always the operating system on which the computer works. Operating systems are designed to provide security for users, but there are always loopholes in them. System manufacturers are flying in real time and you also need to update your system regularly to avoid exposure. In small companies it is best to do it fully automatically, but such updates are sometimes associated with problems, so in larger companies it should be managed by an IT specialist.
Some unwanted and malicious software will always get into the system, especially if the computer user is irresponsible. In such a situation, it is necessary to use appropriate cleaning tools, which are able to neutralize and remove such problems.
