Since late September 2013 I'm having Windows Defender detect and quarantine Trojan Dropper msil livate.a After I tell Windows Defender to remove the virus, I have also Malwarebytes Pro scan my entire laptop. I also have Windows Defender do full scan. Both Windows Defender and Malwarebytes Pro detects no such virus. However, a few days later, if I open say Firefox or Internet Explorer, Windows Defender will again detect and quarantine. Windows defender detects the virus and quarantine only when I open a web browser. I do another Windows Defender and Malwarebytes scan after updating the signature and again, nothing is detected. I have also run HitmanPro_x64. Likewise nothing of this nature is detected. This cycle keeps repeating itself. Is there anything I can do to solve this problem short of reformating the harddisk and reinstalling Windows 8. If in the event I have to reformat the harddisk, is there a necessity to uninstall Malwarebytes Pro first ? Then after formating and reinstalling Windows 8, will I be able to reinstall Malwarebytes Pro and reactivate ? Or activation is based on the identfiers in the laptop, ie machine specific, meaning there is no need to uninstall before reformatting ?
