I have recently been experiencing problems with my PC going in to moments of (Not Responding) status.
I notice it most with firefox because that's what I use most of the time. I have seen the same issue while trying to work in winmail

I even tried Google Chrome to see if it was directly related to firefox or an add-in.

Even typing this message is a chore as things keep "pausing" Sometimes my KB input is still captured - sometimes it is not and I have to type things over again.

I use F-Secure provided by my ISP. It is up to date.
I couldn't run F-Secure in safe mode.
I have run updated mbam and sas. Both in "regular" mode and safe mode. mbam found the notepad registry entries "bug" that they report as a non-issue.
I removed them anyway.
I also use iolo System Mechanic to keep things tuned up.

Looking at Task Manager, I see that fssm32.exe is using a lot of memory 388,568 K at the moment and climbing. CPU utilization is high as well - 50 to 70%
I thought that was normal as I had the scan settings set to run after 5 minutes of inactivity. But it never would stop climbing when I start using the PC.
F-secure doesn't have any way of indicating that it is doing a background scan. So, I'm not even sure if it is doing that.
I changed the settings to scan at a specific time but the problem still exists with pauses and fssm32 eating up resources.

While searching for a solution, I cam across this thread here and I fear I might be taking the same path.
http://www.bleepingcomputer.com/forums/t/248573/one-cpu-of-a-pentium-d-dual-core-pegs-at-100-malware/
I'll wait for guidance though.

For me, the app that doesn't seem to want to close is firefox.

Also, IE has not run on this PC for a LONG time. I always get a rundll32.exe DEP error
I do get DEP errors with WMV files as well. I just haven't figured out which codec is the cause - if it is a codec.

Also of note is that I recently removed 2 GB of RAM as I was getting a BSOD every day. While I can't pin it down for certain, I suspect that they were caused by F-Secure because they would always occur with .sys files that begin with the letter 'v' Such as vmci.sys for vmware or volmgr.sys for windows. I suspect that F-Secure was getting that far in the scan before encountering a problem.
The MS debug tools indicated memory corruption as a likely cause. So, I took 2 sticks out and ran memtest86 SMP on the remaining and it tested out fine. So, I've just been running with 2 GB since. I realize that 4 GB was too much for 32-bit Vista, but it ran fine for quite a long time.

Thanks in advance for any help.

Just finished scanning with Sophos Anti Rootkit and only some unknown hidden files reported - no recommended for removal.

I'm sorry, that's the one thing I didn't do is save the report. I figured there was nothing recommended for removal so it wasn't worth saving.
I just looked for the log file in %TEMP% and came up empty.

I can run another.

Something to note: When I opened up firefox to post this message I got an almost minimized firefox window opened up in the background. I expanded it and there is nothing there. I have the NoScript add-in. If I right click the blank page, I get a menu option to forbid about:blank.

Am I looking at the about:blank infection?

This is not a normal case, basically nothing is showing up in Sophos. How good of Windows maintenance do you perform? (Ex: Defragging, Cleanup Files, etc.)

And also after that, lets get a second opinion:

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the FILES tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

iolo System Mechanic does cleanup daily. Even still, I double check more than twice monthly.

I tried running root repeal and it got stuck at the Initializing dialog. That's how I ended up going to SAR. But I'll try it again now.
Since it won't open at all, I can't get to the Settings - Options menus...

Ok, Dr. Web time:

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

I just wanted to let you know that I haven't abandoned the effort.
I started the DR Web scan on Wednesday night and it's still running. It IS running, too. Just over 4 million objects scanned and I'm about 75-80% through according to the blue bar along the bottom. :thumbsup:
So far, nothing is listed.

Cheers.

Oh, and I'm posting from a completely different computer..

When I try to run the ddr.scr file, it just opens up in notepad.

I do recall setting that up as a safety a long time ago. So long ago that I do not recall where I did it - whether it was part of a program that I ran or a setting that I tweaked in Vista.

Edit: I just got it started by right clicking and selecting configure. I'll see how far it goes..
