Hello! Please help me to remove from my PC "Trojan-Proxy.Win32.Dlena.an " since my Antivirus Kaspersky 6.0 is able only to locate it but does not delete from my system.
"Trojan-Proxy.Win32.Dlena.an
Bad URL removed
After I got a message showing that I have a virus I disconnected PC from the Local Network and Ineternet to urn the Virus Check which told me that the virus is found and cured .However, when I reconnected the virus activated and the following virus messages started to pop-up
" C:\WINDOWS\system32\32119532ld.exe" again.

Somebody please help me!

Thanx for your research! The problem is that the file ,which I thought, created the problem and it was proved by Kaspersky is "rpcc.dll" and I HAVE ALREADY REMOVED IT. In my view the core of the virus is hiding in the REGISTRY and everytime I am connecting through Loca Network to the Internet this virus gets new forces form the URL which I have posted before. As for the process tree, I am not quite sure that i am able to spot strange ".exe" files ,since i am not a pro.Anyway, thanx for your time!

Hi again :)


One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and Download and Execute files

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the Trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud? (http://www.dslreports.com/faq/10451)
When Should I Format, How Should I Reinstall (http://www.dslreports.com/faq/10063)

However, if you do not have the resources to reinstall your computer and would like me to attempt to clean it, I will be happy to do so.
Should you have any questions, please feel free to ask.

Please let us know what you have decided to do in your next post.
