Boa tarde!, comprei um notebook SAMSUNG 500p4c-ad1
Windows 8 64 bits , Core i5 2410m 4gbRAM , 500gb HD S-ATAfaz uma semana ou mais que comprei e estava normal com alto desempenho , nao baixei nada pesado e depois de uns dias a memoria foi a 80% até 100% sem parar e sem esquecer do HD que esta 100% tambem. Fiz de tudo CCleaner Pro , Avira Anti-virus , Malwarebytes Anti-malware e nada. Pelo que eu vi o scvhost.exe ta alto
