Unwanted Malicious Software

I am infected with an unknown malicious software problem.  I am using Windows 10 (64 bit), but this problem also occurred when I was using windows 8.1.  This is the problem:  I get a windows error that says:  Windows cannot find C:\Program Files (x86)\user extensions\Client.exe.  This is accompanied by a windows "Run" window C:\Windows\System32\cmd.exe, that has no entries.  Now I have done a lot of research on this item and have read a lot of useless articles online about this item.  In addition I have done the following:

1.  Run a full system Scan using Norton Premier 360

2.  Gone to the Symantec/Norton web page for help and Ran the offered Symantec Trojan Removal program for 64 bit systems, the Norton Power Eraser (several times) the last time based on written Symantec instructions "I want to Remove  Trojan Powerliks from my computer, specifically the one from the specified Symantec site for 64  bit systems FixPowerlks64-Bit. and all the items contained in the instructions including running Norton Power eraser  and deleting temporary files. 

3.  In addition I examined all the relevant files in Windows System32 files on my computer.

None of the hours spent running all these scans and removal tools touched the problem.

I know everyone is tied up now answering questions from people who "lost" their Symantec security programs when they installed Windows 10, but can anyone help me with this problem?

Re: Unwanted Malicious Software

Hello colapop

Welcome to the Norton Community Forum

I would recommend that you go visit one of the free malware removal sites. Please do not do anything else to try to fix this issue on your own. They will work with you on a one to one basis to help you to clean up your computer. They do not remote in either.

Please see this link for an up to date description of these sites plus the addition of a newly listed site formed by one of our successful malware remover users. The new site is listed first in this link.


Please come back and tell us how you made out. Please remember to stay with the site you picked until your computer is cleaned.



Success always occurs in private and failure in full view. Windows 10 Pro 64 bit Norton Core Security Plus Core Firmware 282 I E 11 Chrome latest version.

Re: Unwanted Malicious Software


If you have any doubts about floplot's recommendation do a Google on:

Windows cannot find C:\Program Files (x86)\user extensions\Client.exe

and you will find many examples over the years of this being the result of an infection and a consequence of your security program removing the item found.

Using one of the free teams that you were pointed to will put you in the hands of dedicated and experienced people who help you analyze your computer and work with you to deal with what is found -- if necessary develop tools they can use to remove your specific invader.

The less you do or let others do before consulting one of them the more likely they are to be able to help you.
