Just joined this site after becoming very frustrated with my computer. I've been through the checklist for slow computers and done almost everything suggested. Performance has improved slightly.

When I run Task Manager to see what's running I see several programs I don't recognize or I am unsure about. They are using alot of memory. Here they are:

iexplore.exe (I assume this is Explorer and is ok)
msimn.exe (The startup list indicates this may be a bad program but I'm not sure)
explorer.exe (another Explorer file?)
svchost.exe
msmsgs.exe
ccSvcHst.exe

Any suggestions? If these are indeed worms or viruses what do I do?

Thanks in advance.

Anytime you come across a suspicious file, search the name using Google, BC's File Database, File Research Center or the Process ID Database. Also see How to determine what services are running under a SVCHOST.EXE process.

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 on your computer. A file's properties may give a clue to identifying it. Right-click on the file, Properties and examine the General and Version tabs.

You can download and use Process Explorer or Glarysoft Process Manager to investigate all running processes and gather additional information to identify and resolve problems. These tools will show the process CPU usage, a description and its path location. If you right-click on the file in question and select properties, you will see more details about the file.

Anytime you come across a suspicious file which you cannot find any information, 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.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.

Also see Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.
