Serious antivirus software has long become an integral part of any computer. Both in offices and on home devices, an antivirus is required. But it often happens that for proper operation many different conditions are necessary: timely updating of anti-virus databases, license renewal after a certain period.
What are the utilities for?
Antivirus programs that are installed on the computer work at a high level. Scanning for viruses is recommended low before the operating system boots up. And in such cases, free utilities come to the rescue.
Anti-virus light programs are developed by many computer security manufacturers. These utilities do not require installation. They run without problems on computers with installed antiviruses, without causing conflicts. Regular updates are another plus. If the operation of a conventional antivirus raises questions, then checking with an antivirus utility will help solve the problems.
