I have recently brought Intel i7 laptop and it was working fine. I install Microsoft security essentials on my system and run a full scan and it detected a Trojan downloader win32/Bredolab.x? But when I try to remove it, this trojan is not getting deleted. I do not have any idea from where it came to my system, but yesterday while surfing I got a message saying software installed successfully and this may be the source of entry. Now I want to remove/delete this from my system? Microsoft security essentials does not say the location of file. Thank in advance for your suggestion.Your effort would be appreciated.
