Hi, i did a scan with AVG and it came up with this:

detection name: i8042prt.sys, hooked import HAL.dll READ_PORT_UCHAR - sphn.sys +0x11B90
description C:\windows\system32\drivers\sphn.sys
severity: medium

Then I tried to remove it and it didn't

Same problem..

Hi, today my AVG found the following:

"";"C:\Windows\System32\Drivers\spne.sys";"Inline-Hook ataport.SYS DllUnload -> spne.sys +0x5E360";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"atapi.sys, Import-Hook ataport.SYS AtaPortReadPortBufferUshort -> spne.sys +0x2D35C";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"atapi.sys, Import-Hook ataport.SYS AtaPortReadPortUchar -> spne.sys +0x2D224";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"atapi.sys, Import-Hook ataport.SYS AtaPortWritePortUchar -> spne.sys +0x2DA24";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"atapi.sys, Import-Hook ataport.SYS AtaPortWritePortBufferUshort -> spne.sys +0x2DBA0";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"pci.sys, Import-Hook ntoskrnl.exe IoAttachDeviceToDeviceStack -> spne.sys +0x62650";"Verstecktes Objekt"
"";"C:\Windows\System32\Drivers\spne.sys";"pci.sys, Import-Hook ntoskrnl.exe IoDetachDevice -> spne.sys +0x625DC";"Verstecktes Objekt"

(verstecktes Objekt means hidden object)

It seems to be similar to this thread: http://forums.avg.com/ww-en/avg-forums?sec=thread&act=show&id=208665

I hope this is a false positive too and AVG will updates its signatures soon.

solved..

The latest signatures fix the problem, the file is no longer marked as a rootkit.
