It seems during the July 28, 2010, ESET NOD32 added the Kunhitta.A Trojan to their database My system (Windows XP pro SP2, Mozilla Firefox, ESET NOD32 antivirus), since July 29th, it seems to connect with ; the connection is blocked by Nod32 (Kunhitta.A trojan horse), but it reconnects and NOD32 blocks ... and so on. I have to end my connection in internet to block the process completely. Same situation on july 30th and 31st. After lots of events like that, today I found a file "zaeemu.exe" in C:\Documents and Settings\<user>\Local Settings\Temp. This file has been run by windows explorer.exe automatically (I didn't click on it): I was only looking at the folder. NOD32 has blocked it. Hijack this log is clear, NOD32 doesn't signal any virus and the system seems to run correctly. This evening the process started again and I found another file ".exe" in "C: .... \Temp" folder. I cancelled it , but I fear that tomorrow the process will start again. Can anybody help me with any advice ? Thanks in advance
