I am running Exterminate It! on my Vista laptop and it keeps reporting a Malware Agent in the Backdoor Trojan category with a location name C:\Windows\TEMP\symlcsv1.exe. I run Exterminate It! and wipe out this file, then run Exterminate It! again and it shows clear but the file comes back at some point because now, every time I run Exterminate It!, the symlcsv1.exe file shows up. Is this a dangerous file? If so, how do I get rid of it permanently? If not, how do I differentiate between a dangerous file and a harmless file?
