Atenção, alguns sites estão relatando que este aplicativo pode conter um trojan (Application.RemoveWGA, not-a-virus.Risktool.RemoveWGA).

Em contra-partida a Softpedia ( um dos maiores sites do mundo ), menciona que o produto é perfeitamente seguro e que o aviso é de falso vírus.

"Note: Some antivirus and antispyware programs flag RemoveWGA as being infected/malware, although the application is perfectly safe and does not pose a threat to your system. This is called a 'false positive'. The term false positive is used when antivirus software wrongly classifies an innocuous ( inoffensive ) file as a virus. The incorrect detection may be due to heuristics or to an incorrect virus signature in a database. [Similar problems can occur with antitrojan or antispyware software.] "

Sugiro instalar um bom antivirus antes de descompactar o programa.
