Explorer "Not Responding"; Freezes Up

[peterwk]

Windows 7 is becoming unusable for me, because Windows Explorer keeps locking up. Just now I opened a folder, trying to access a drive on another computer on my network, and it froze. I often get it when using File Save As in various applications - as you can imagine, it's hard to use one's computer if you can't save files and you can't open directories!

It's not all the time, though. In the best Windows style, it drives me nuts for a day, then backs off and lets me think everything's okay for half a day or so...then comes back and screws me again.

Here's what I see in Event viewer:

The program explorer.exe version 6.1.7100.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

After using Windows for almost a quarter of a century -- and hoping that Windows 7 was finally the fix I've been waiting for for all these years -- I'm almost ready to switch to a Mac! Please save me!!!

Given Explorer.exe hasn't been around since 1984 I think you're exaggerating

For starters:

- Does it only happen on network drive access or have you observed the exact same issue when saving to local drives?

- If it's only network drives, can you reproduce the same symptom if you boot to [safe mode + net] and try from there?

- If it also does the same thing when saving locally, what about if you boot to safe mode (without network)? Does the same thing sometimes happen?

- What antivirus are you using? Have you tried deactivating it or (even better) uninstalling it long enough to be sure whether it has any effect?

 

[peterwk]

I've been using Windows -- not explorer -- for almost 25 years*, and no, I'm not exaggerating.

It's not just a network problem; just now I opened File > Save As in Word, and didn't even get a chance to pick a location before it locked up.

I'm using AVG; good idea, I'll try turning it off for a while...thanks.




*Actually it's probably been almost 24 years: wiki

 

[peterwk]

Update ... I disabled AVG almost 4.5 hours ago, and things are working well so far! (BTW, AVG, it's kinda arrogant to not provide a simple way to disable your software.)

So, I guess I'm going to need another Anti-Virus system ... I'm going to run without AVG a few more hours, but it's certainly looking like AVG was killing Explorer (and various other little problems I hadn't mentioned before, such as stopping my desktop copy of ACT syncing with my Web-based copy, seem to have gone away).

Any recommendations anyone?

 

[mickey megabyte]

if you mean recommendations for av software, there are lots of threads in the 'system security' part of the forums.

fwiw, i like kaspersky 2010, although it's not free for most people.

 

[Uber Philf]

Avira, id recommend

 

[jfar]

Yes, you can't go wrong if you you choose Avira, it's free, and it updates every day.

I used Avast Pro for several months. I purchased ti from a friend's shop.

It was pirated and the key got blacklisted after a few months. Biy was I pissed.

But I really liked the app. I like the way it handled script blocking and web page scans.

That was right about the time I installed the "RTM" and I installed AVG out of habit. No issues.

When I get my final version of Win7 in November, I will return to Avast Pro.

Glad to hear it, but unless you knew of a 100% reliable way to bring about the problem previously, a lack of symptoms for several hours may not be conclusive.

In fact, none of the AV vendors provide a simple way to disable their stuff - it is architecturally very difficult to do. What most people think of when they visualise their AV solution is the "pretty" UI applet they use to configure it, or even the (Win32) services installed by the app. However, it's the kernel-mode filter driver(s) that does the real work, and the UI applets/services are just a means of getting config info down to the driver. You can stop the AV services and request that it Temporarily Disable Realtime scanning in a variety of pretty ways, but in reality the user has no idea what stance the kernel-mode filter (which is still plugged into the I/O stack) has adopted. It's entirely up to the AV vendor to provide their own definition of what "disabled" means to them, because it's far from trivial to just switch off a filter driver which has its hooks in the deepest nooks and crannies of the OS.

Therefore, the only way to be sure that the AV is "deactivated" is to uninstall it. Unless even the uninstall routine is borked, the act of uninstalling will deregister and remove the filter driver(s) - at least upon reboot.

So, I guess I'm going to need another Anti-Virus system ... I'm going to run without AVG a few more hours, but it's certainly looking like AVG was killing Explorer (and various other little problems I hadn't mentioned before, such as stopping my desktop copy of ACT syncing with my Web-based copy, seem to have gone away).

Any recommendations anyone?

Personally, I don't use AV software on my own machine. That's not the correct approach in all situations, but it works for me. I rely on a mix of being redundantly backed up, careful about what I run, and always using an unprivileged (non-admin) account for daily tasks.

The obvious exception is when I've got a downloaded executable that I want to run without being 100% sure of its cleanliness. An AV scanner _without_ a driver can go over the files in a directory structure and tell me whether it thinks they're OK. For example:

ClamWin Portable | PortableApps.com - Portable software for USB drives

Because of the lack of a kernel-mode driver and low-level integration, it cannot perform real-time scanning, but then that's exactly the way I want it in this particular setup.

Hope this helps. (BTW, I was being facetious with the "1984" comment. The mental image of somebody seeking "a fix" for their UI freeze issue for "a quarter of a century" was somewhat amusing. No offence intended )

Fixed windows explorer not responding

I have Windows 7 RC 32-bit Build 7100 which I installed onto Vista,ie, I did not do a clean install. This problem did not start happening for some weeks after install and I don't know what caused it. But I fixed this problem with an inexpensive commercial product that was already available on my machine-Avanquest System Suite 9 Pro, fix-it 9. I just ran its one click scan and after it finished the problem was gone!!! I am not affiliated with Avanquest. Maybe other virus scans, etc would do the same thing. But before this, Windows 7 was unusable and I would go to my other machine windows 7 RC 64-bit which I did do a clean install on that never has problems.

Windows 7 is becoming unusable for me, because Windows Explorer keeps locking up. Just now I opened a folder, trying to access a drive on another computer on my network, and it froze. I often get it when using File Save As in various applications - as you can imagine, it's hard to use one's computer if you can't save files and you can't open directories!

Thanks everyone for your help.

I did use Avanquest System Suite 9 Pro's registry cleaner - however, it modified some settings in my registry that killed Explorer. (Fixed it .. found a registry fix for that issue somewhere.)

I left AVG off for a while, then reinstalled it ... then uninstalled it. I'm not 100% convinced it was AVG, as the second time I ran it it wasn't quite as bad as before ...still had problems, though. Now, without AVG for a few days, things seem to be running nicely.

For AV I'm using the beta of Microsoft Security Essentials (http://www.softpedia.com/progDownload/Microsoft-Security-Essentials-Download-131683.html), the replacement to Live OneCare.

 

[stewarta13wsb]

The desperate search for a solution brought up this old thread... re. the last post, I'm already running MSE (way past the beta now of course) but I've got the 'explorer not responding' issue for a few weeks now.
Although there are lots of posts here, my usual source of solutions 'VirtualDr' don't seems to have heard of this issue - I thought it was just me for a while... until I googled

Clean install of Windows 7 Ultimate 64 bit.

Also running PC Tools Firewall and Spysweeper.

It keeps reporting the problem to Microsoft but nothing back yet. I read somewhere about switching off 'protected mode' in IE8 but I don't think that's done anything and I uninstalled Super Anti Spyware as it was mentioned in one of the event logs.

Any progress with this issue??

Thanks,

 

[peterwk]

I Fixed It

I fixed the problem by removing references to certain network drives in Windows Explorer. I had listings pointing to Web sites I had worked on using MS Frontpage, and an entry for MSN Web Sites for some reason...I had never used that service, but some program put it there during an install.

This is apparently a known bug; at least, known to non-MS people, though evidently MS itself doesn't know or care to know.

 

[stewarta13wsb]

Thanks for that Peterwk, but can I ask for more information...
How do I go about doing what you did and what should I be removing, or how will I know what to remove? Make it as simple as you can please!!

Thanks,

STOP USING INTERNET EXPLORER!!, It is a VIRUS MAGNET, use Firefox, Opera or Chrome, "Safer, Faster, Better"

 

[peterwk]

Can't Quite Remember!

Sorry, I can't remember exactly what I did. In general terms ...

Look for these extra items in Windows Explorer; look for references to external "drives" that don't really exist, such as FrontPage Web sites and MSN Web sites.
Right-click on them ...
Delete them

I also stopped using Windows Explorer ... I now use Directory Opus, a much better file manager, that also seems to be more stable. GPSoftware Main Index
