Windows Defender: False alarm triggered by hosts file

[ronjor]

-{ Quote: "Since Monday evening, Microsoft's Windows Defender spyware detection software has mistakenly raised the Win32/PossibleHostsFileHijack alarm on some clean PCs. According to Microsoft, the error is caused by a flawed signature deployed via automatic update on Monday. Another signature update has now been issued to solve the problem." }-The H Security (http://www.h-online.com/security/Windows-Defender-False-alarm-triggered-by-hosts-file--/news/112814)

:-\ I received this "false alarm" after updating to 1.53.256 & later scanning. I chose to put "the culprit" in quarantine until the so called problem had been clarified by MS. I am unable to restore the quarantined item as "restore" is greyed out & is unavailable. [The only option available is "remove all".]
I have since updated to 1.53.288 which I understand corrects the false positive. [but not my dilemma.]
I also read the article / advice in H security but was unable to follow the recommended actions via Notepad.


Edited later - I rebooted twice, & "restore" reappeared & I was able to return the "false positive" file. All is well! [ we hope]
