Then, in early October of 2015, Symantec announced that it was breaking up the company into two separate companies, one focused on security and the other on information management.What’s really strange about all this is how “quietly” it happened. (CLICK HERE to read their news release on the breakup).And to make matters even MORE mysterious, especially for “consumers” who use their Norton products, if you visited the Symantec web site it was actually difficult to find information about the Norton products!The product received generally positive reviews praising its user interface, low resource usage and freeware license.It secured AV-TEST certification on October 2009, having demonstrated its ability to eliminate all widely encountered malware.
At any time protection is as up-to-date as possible with available data user side and Norton side.Symantec, Mc Afee and Kaspersky Lab—three competing independent software vendors—dismissed it as an unworthy competitor, but AVG Technologies and Avast Software appreciated its potential to expand the consumers' choice of AV software.AVG, Mc Afee, Sophos and Trend Micro claimed that the integration of the product into Microsoft Windows would be a violation of competition law.English, Bulgarian, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Latvian, Lithuanian, Norwegian, Polish, Portuguese (Brazilian), Portuguese (Portugal), Romanian, Russian, Serbian (Latin), Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian and Vietnamese Microsoft Security Essentials (MSE) is an antivirus software (AV) product that provides protection against different types of malicious software such as computer viruses, spyware, rootkits and Trojan horses.Before version 4.5, MSE ran on , Windows Vista and Windows 7, but not on Windows 8 and later, which have built-in AV components.
