Today i've scanned my PC with the new version of AVG FREE 2015 and it reported that i'm infected with a Trojan Small.FHT found at C:\Windows\System32\MRT.exe
I've surfed the web for a while searching for solutions since it says that it can't be removed because AVG can't find the object.
I've manually looked in System32 and i've found there MRT.exe
It is digitally signed by Microsoft so i thought it was a false positive.
It's 96 MB and i've scanned it also with ESET and Malwarebytes and no problem was found.
Can i be sure that it's a false positive?
