BleepingComputer.com: about help with processes or .exe on my pc

Norton security quarantined updater.exe, it just said that I was the first one to download this, and not enough was known about it. I wasn't even on my pc today, so I don't know who downloaded this.

There are other things like IP 192.168.1.47
IP: fe80::d164:2220:9597:d416%8
MCUI32.exe
WerFault.exe
explorer.exe
2 iexplore.exe, one using 49,712 and the other using 6,052
system32/csrss.exe
system32 wercon.exe


Rule "Default block Windows File Sharing" blocked communication. Process name is "System".

I was just wondering if there is a safe site that I can use to look these up, and some processes that I was wondering about. If someone could let me know thanks in advance.

Most of the processes in Task Manager will be legitimate as shown in these links.

Anytime you come across a suspicious file or one that you do not recognize, search the name using Google or the following databases:

• BC's Startup Programs Database
  
• SystemLookup StartupList Index
  
• File Research Center
  
• ProcessLibrary.com

Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location (folder) than where the legitimate file resides and runs from there. Another techinique is for the process to alter the registry and add itself as a Startup program so that it can run automatically each time the computer is booted. A file's properties may give a clue to identifying it. Right-click on the file, choose Properties and examine the General and Version tabs.

Tools to investigate running processes and gather additional information to identify them and resolve problems:

• AnVir TaskManager Free
  
• Process Explorer
  
• System Explorer
  
• ProcessHacker
  
• Process Monitor
  
• svchostViewer

These tools will provide information about each process, CPU usage, file description and its path location If you right-click on a file and select properties, you will see more details.

Anytime you come across a suspicious file for which you cannot find any information about, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
