I have a problem. I semm to have a memory leak. When ever I use the windows explorer, my machine slows down (crawls actually). I looked at the task manager to see what the problem was. My CPU usage in normal (decent % for the programs used). In the processes list, explorer.exe seems to be out of control! It goes from about 15,000 k to 28,000 to 40,000 and so on. I have seen it at 254,000 k. The commit charge also skyrockets; it usually is around 600-900M when this problem happens. What's worng with my computer?

I know it's clean; I used McCafee virusscan, Trend midro onlie virusscan, adaware (updated), spybot(updated), CWshredder, MS anti-malicious program tool, the MS RAM tests, flushed all temp files and drefrag all partitions/hd. SP 2 is installed. I'm just about out of options.

ANyone can help? Thanks

If you end task explorer.exe and start it again, does it continue to climb? The highest I've ever seen mine was 90,000K, and it hasn't come anywhere close to there since. Normally mine runs between 10,000-40,000K

I tried a few time. Each time disaster struck. The WIn taskbar vanished along with everything else. All I could see was my wallpaper. I could use nothing except the taskmanager. I couldn't even get the command promt by the kb shortcut). Each time I had to end my session and logon again.

When that happens, in the task manager go to File>New Task>explorer.exe

I have the same problem (description is identical as above), but I have never used the Windows Explorer tree view (I actually don't like it); for the rest, I am reasonably sure that my computer is clean from viruses/ad crap/etc. -- Does anyone know whether the fix proposed by Chuck2 is suitable for my case or not?

Thanks in advance,

Yuck - I had that problem where the explorer.exe kept climbing and my laptop would act like junk and I would have to reboot. Most advice I got was "relaod and reinstall"

I don’t even think I still have all the software on my laptop, so I was desperate. A two week-long process of spyware, malware, virus and memory leak investigation and troubleshooting got me back to a pretty good state, and I learned alot. A few things:

ONE

The Panda we used found a virus that was causing much of the trouble for me – unfortunately, Panda did not have signature for it until yesterday (Mcafee still doesn’t) You can tell when you have it by opening the task manager and looking at the processes and seeing if your explorer.exe is growing steadily for no reason. It should be somewhere around 20,000k. For that matter you should never have any process that is steadily increasing RAM consumption when your not doing anything. The file specifically holding the virus was CHUPV.DLL


TWO

If you have ANY of these files in you windows or windows subdirectories – then you’ve got some nasty malware that spybot/adware can’t find and you need to start in safe mode to delete:

CHUP32.DLL

CHUPV.DLL

TXDB32.DLL

SRPCSRV32.DLL

SPOOLSRV32.EXE

I would still download the latest adaware SE and the new spybot (both free) BUT clean your cookies and cache before you run then otherwise you’ll have a ton of stupid hits to sort through. It will find a lot of stuff.

THREE

Most shareware doesn’t have a clue about windows memory management, so it causes HUGE memory leaks that occur under memory intensive programs like (Visio and Photoshop) so I found a great free program called Clean RAM that is also free. You run it after you’ve been using Windows for a few hours, and it goers and retrieves all the memory lost to memory leaks – works really good (stops me from having to reboot after doing the Visio/Photoshop/Netobjects thing)

The link is http://www.nomorehistory.com/clean_ram.html It is free, but you can buy the professional edition (I didn’t the free version works fine for me)

FOUR

Finally, my machine got a new lease on life by fixing the over 600 registry problems it found by buying a program called registry mechanic

Hope this helps someone - My machine is like new.
