A AV-Test 2015 divulgou os resultados do primeiro teste deantivirus para Windows 10. Os dados surpreendem, ja que colocam o Avira,antivirus gratuito, no topo, empatado com concorrentes pagos e reconhecidos. Ostestes da instituicao alema sao realizados para observar uma serie decriterios, que vao desde a precisao na hora de encontrar virus ate o desempenhodo aplicativo no contexto do sistema operacional.O teste atribui um total de seis pontos para cada categoria:protecao, performance e usabilidade. No total, 20 antivirus foram analisados,dos quais quatro receberam a pontuacao maxima: Avira, Bitdefender ,KasperskyLab e Symantec.Alem do fato de que a pontuacao maxima e de um antivirusgratuito, equiparavel a opcoes pagas, outro dado que surpreende na pesquisa e aposicao do software de seguranca da Microsoft. O Windows Defender, aplicativocaseiro do Windows 10, somou 3,5 em protecao, a nota mais baixa nesse criterioem todo o teste da AV-Test, e ficou em antepenultimo lugar. Em performance, aMicrosoft conseguiu 4,5 e nota maxima em usabilidade.Confira a lista completa dos melhores antivirus na tabela aseguir: Leia o artigo completo em: http://www.techtudo.com.br/listas/noticia/2015/11/av-test-os-dez-melhores-antivirus-para-windows-10.html Teardowns of the iPhone 6s and 6s Plus have revealed two different A9 chips inside the devices, onecreated by TSMC and one developed by Samsung, which is slightly smaller insize, having been manufactured on a 14-nanometer process instead of a16-nanometer process. There wasearly some speculation that the chips were divided by model, with the iPhone 6sgetting the smaller Samsung chip and the iPhone 6s Plus receiving the largerTSMC chip, but new data collected by an iOS developer suggests that is not the case. HirakuWang has created an app that's able to determine whether an iPhone has a TSMCchip or a Samsung chip, and has shared some data on results gathered from userswho have installed his app. Accordingto results from approximately 2,500 iPhones, there are more TSMC chips thanSamsung chips. TSMC chips were found to be installed on 58.96 percent ofdevices, compared to 41.04 percent for Samsung chips. TheiPhone 6s Plus appears to have relatively equal split of Samsung and TSMCchips, with slightly more Samsung chips. Of 1,329 iPhone 6 Plus devices, 56.81percent have the Samsung chip while 43.19 percent have the TSMC chip. With theiPhone 6s, the numbers skew heavily towards the TSMC chip. Of 1,086 devices,78.27 percent have the TSMC chip while 21.73 percent have the Samsung chip. At thispoint in time, there is no evidence that the two chips perform differently, asmore extensive testing must be done to determine any performance discrepancies.Though the chips are two different sizes, it's highly unlikely there are goingto be performance differences large enough to be noticeable during daily usage. It ispossible for users to check which chip version is installed in their iPhonesusingWang's utility, but users should be cautiousabout installing an app via enterprise certificate from an untrusted developer. De tempos em tempos todos precisamos atualizar nossas plataformas Microsoft Office. De um lado ou de outro, uma migracao desse tipo gera impactos que sao previamente estudados pela Infraestrutura de TI.Os estudos de compatibilidade consideram o cruzamento entre os recursos suportados pela ultima versao, release ou service pack, e aqueles utilizados na operacao.
