I am working in IT company and at manager level post. Recently, i purchased a laptop(i.e DELL Studio 14) with configuration:Intel Core2 Duo Processor with chipset of Cantiga GM45, 1GB ATI Mobility Radeon HD 4530, 4GB DDR3 SDRAM, 512GB HDD and Windows Xp as operating system. My laptop is also used my son and wife, they use for internet, gaming ,etc purpose. Yesterday, got an alert from my McAfee anitvirus that "TROJ_HYDRAQ.A is found". I don't what this alert exactly means? Is it any malware or trojan? and please tell how to remove it?
