If anyone has any info on this please give some feedback. So we have a wide variety of computer systems here at work with operating systems windows 7 win xp win 8.  So this morning on 1 computer it started saying system memory error programs need to close.  Then on another system its doing the same and now 10+ are doing it.  I ran all the usual scans and security tools with windows in safe mode and windows in normal boot mode.  Didn't come up with anything.  I do notice at when the error occurs there is a svchost eating up almost all the memory on that particular system. What does this sound like to you guys?

This is a zip-file which you will need to extract the application from.  
 
To extract the application click on shexview.exe, and then click on Extract All.

Click Extract in the next window that opens.
 
Another window very similar to the first one will open, click on shexview.exe

In the next window click on Run to start the installation.
 
A image similar to the one below will open, this will show all of the shell extentions.

To find the shell extention which is causing the problem right click on a non-Microsoft shell extention, the non-Microsoft shell extention should be highligjted in pink.  Under the column titled Company you can see the programs listed as Microsoft Corporation, do not disable any of these.
 
Find the non-Microsoft shell extentions starting at the top of the list and right click on the shell extention and choose Disable Selected Items.
 
Restart the computer to see if this has resolved the problem.  If it doesn't resolve the problem go down to the next shell extention and repeat this process.  Continue this process until you find the shell extention that is causing the problem.
 
After you have found the shell extetion which is causing your problem click on [b'View[/b] and choose HTML Report - Selected Items.
 
Highlight the Shell Extentions List, copy it and post it in your topic.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

So there were 6 highlighted in pink I copied and pasted them below. I didn't go through 1 by 1 and diable and restart because it doesn't pop up right after a restart.  It would take over and error to eliminate those 6 1 by 1.

Here is a screener of the error on a windows 7 machine

and here is a screener of the task manager in windows 8 with a similar error worded differently.

So it's a process that builds and builds and eats more memory until it crashes programs and then it builds more and uses more memory.  Any ideas?

You have a widespread infection.  Time to change your policy on people bringing infected Pendrives, and other media into the office, and plugging in, along with not having a policy to scan email attachments.

 

See this previous post, and follow the directions for scanning all machines http://www.bleepingcomputer.com/forums/t/425587/svchost-infection/
