Same thing happened to me:
hpslpsvc32.dll is marked as containing “Backdoor.Win32.PcClient.~a[at]88561940”
False positive?

Hi chupachups,

Pls check the product version and DB of CIS.If happened again,pls make a shot and post it in the forum,also the system version.

Thanks and Regards,

Thanks it was with Version<3.13.126709.579> (and latest DB).

I’m sick of HP junk/crapware anyway. It is insane how far they populate windows services and system. I run the same printer from linux faster and without all theirs spying dlls …

I reformatted my laptop yesterday and installed CIS Product Version: 3.13.126709.581.
I have installed system updates from Microsoft except for SP2. Every time I attempt to install the update CIS finds

Name: backdoor.win32.pcclient.~a@88561940

Location: C:\windows\winsxs\temp\pendingrenames\0c12da38a991ca017d0200004010581c.x86_microsoft-windows-dns-client_31bf385ad364e35_6.0.6002.18005_none_e3cdf5e97f7b2eb7_dnsrslvr.dll_faf65b7a

Is this the backdoor Microsoft said didn’t exist or is it a false positive?


Hi Snowshagger,

Please send this file to us using Webinterface for detailed analysing.

I got the same HP HPSLPSVC32.DLL alert.

The alert happens immediately at windows xp startup.
But later, when I run the virus scan manually it does not alert this file any more .

Hi Ionel
Tried 2 do that, but file doesn’t exist anymore within 2 minutes.
I’ve sent the files with the option in main Comodo feature.
I don’t know if u will be able to review it, but I didn’t saw another way.

for now, as my vista is crapping due 2 error after error in installing SP2, which never passes the 80% mark, I see myself forced 2 backup and format and install this laptop again.

Kind regards and thanks for looking in to this kind of problems

This false-positive is already fixed with DB 3596. You can check to confirm.


Hi All

I have a similiar problem with a Toshiba Laptop running on Vista Home premium. I had the SP2 installed and had no problems until I took I had to ship it out to the authorised service centre for a hardware failure, I got it back from the service on January 7th 2010 and they had reimaged the HDD and I had to do all the updates and found out surprisingly that CIS was preventing the SP2 for being installed.
CIS log: C:\Windows\winsxs\Temp\PendingRenames\bd08559b989dca0163270000a4044c11.x86_microsoft-windows-dhcp-client-dll_31bf3856ad364e35_6.0.6002.18005_none_d945a2ac2bb19ac6_dhcpcsvc.dll_8155446a[/size]
I red all I could about this problem and I could not find a solution. I tried to upload the file to be checked online but I had no permitions to do so, thus I took ownership of the entire folder but I still could not send the file for upload.
I turned off CIS thinking that of all the “hackers” in the world Microsoft is the “less harmful”, and managed to install SP2, but CIS was still reporting the backdoor present. I think I got rid of the backdoor files through AVIRA Antivir and everything seemed to be working fine but I noticed an accessive amount of reports in the CIS logs of my OS IGMP packets being blocked and in the same time ICMP packets from Microsoft Servers.

I reimaged the HDD and I’m at the point where I’m about to install SP2 again that is still failing due to the same reason.

Please if anyone can help…

Thank You in advance and Kind Regards

Hi enhazi,

Thanks for reporting.Please add the detected file in exclusion list and then try to submit at Comodo Firewall | Get Best Personal Firewall Software for $29.99 A Year.


Hi Haja

Thank you for replying. I tried but I could not get to upload the files, however I tried to install SP2 once again and I noticed that the filename this time has changed and I did select to exclude it and I was able to upload it. Thus my SP2 was successful.
I would have like to have had some info on this issue before I installed SP2, however it is done now, waiting to get the results of the file I uploaded.

Thank you once again, regards
