random high cpu usage with explorer.exe

[VistaKing]

I'm not seeing anything no malware that could be causing the issue . What does process explorer show ?

 

[timeless]

uploaded a saved log of current processes.

 

[VistaKing]

I'm noticing this


C:\Windows\Explorer.EXE
C:\Windows\explorer.exe
C:\Windows\explorer.exe


Right click on C:\Windows\Explorer.EXE and choose properties and see what the location is from . Or if you end task it does the Taskbar disappear

lm not seeing it in process explorer. or should l say lm not seeing one thats capitalised. a search of my windows dir does seem to show a few instances but all bare microsoft signatures by the looks of it and seem to match the crc of the original.

l will however keep an eye on process explorer to see if l notice anything.

Your other scans come out clean .

well my current thoughts are about my own virus scanner.. lm wondering if when my issues with the explorer.exe usage could be occurring when bitdefender experiences a random blip in its scanning engine.

you see lve had bidfender virus shield randomly stop without warning a few times before, in addition to that when l have my mkv freeze problem (when it occurs which is entirely random like my above issues) if it relates to BD wanting to scan specific files which use certain codecs tho l cannot be sure since l do know it happens on specific files but l dont find a correlation always between what each file uses when l check codec information.

however with regards to the above explorer.exe you saw in the logs l have had BD a few times be the cause of a restart of explorer.exe when it happens and warns me that what lm trying to do was seen as suspect activity at those times lve been right clicking and deleting files rather than getting up and grabbing the keyboard lol.

at the moment however lve not heard back from BD so l might open a support ticket.

What if we uninstall BitDefender if the problem is fixed we know who was the culprit

Use Control Panel to uninstall BitDefender once done use the tool below for a clean uninstall.

:ar: Uninstall Bitdefender

ld rather get their opinion before l contemplate it. l recently extended protection and dont want to waste my subscription unless l know its definitely the issue.. at the second its just purely speculation based upon the fact the virus shield has stopped running a few times.. usually starting the service back up fixes it. if that makes sense.

either way if my system runs fine until my next reinstall in a few months l guess ld be happy.. tho in retrospect maybe its a result from when l last reinstalled.. l had a little crash when installing programs l forget which one it was tho the mkv issue started some point after that and explorer issue is more recent.

OP, is that MKV files on a hard drive that the OS is not on, and getting a few secs pause just at the start?

Could be latency from parking the SATA hard drive to actually loading, I have my other HDs sleeping after about 20 mins of non-use, and just waking up is a couple sec lag, even on my speedy system, otherwise, but that protects the HD from wearing out prematurely. [just a thought]

VK running you through all those apps, I had to snag all the ones I was unfamiliar with....

I am considering BitDefender for my next anti-virus/malware solution per avtest.org, what are you saying VK?

BitDefender its ranked on the top 10 of AV software . It is a good antivirus .

By the way congrats to your A+ certification .

 

[Faladu]

Thanks mate, yeah I know, that is why I asked, why you were telling OP to remove bitdefender....?

Were they running multiple anti-virus/firewalls at same time?
Don't do that, ANYONE, this includes the built in crummy Windows one, major performance hit.

 

[VistaKing]

Reason why I asked the OP to remove it for now is cause they said it stopped . Their virus scans come out clean so its not a virus . But when they ran Process Explorer it showed 3 C:\Windows\explorer.exe files .

with regards to hard drives waking up, l actually turned that setting off, so it shouldnt be related to that.

however when the mkv issue does happen it usually freezes the whole system for a few seconds before playing everything as normal. in fact if l really think about it l usually only get the high explorer usage after experiencing a freeze and mostly only seem to notice it around or when l visit sites like facebook or ones containing certain types of dynamic content.. so far its only a couple of sites where lve found it to be noticeable but its annoyingly hit or miss as l could go a few weeks without issue then it happen a few times.

Hard drive is defragmented regularly?

 

[timeless]

my OS drive is an SSD drive which dont need defragging, would lower its lifespan if l did. my other hard drives however do get degragged once a week.. depends on how badly they need it tho.

 

[Faladu]

Right that is what I was asking, the non-SSD fare, I run with 2 SSD's myself, just wanted to eliminate fragmentation as a possible reason for lags, you are well informed, which isn't so typical.

I do get a little disgusted seeing 40% fragmentation on my SSD though. :haha:

Scanned for rootkits lately?

Line by line gone through your BIOS settings?

I finally got sick of Firefox issues myself and switched to Pale Moon, an optimized Firefox, didn't reinstall FF this wipe or any other browser.

l try to keep up on tech.. ld say l know allot more than many but much less than quite a few ppl here LOL. never needed help with xp but win7 has been a learning curve.. and its only really this install lve had issues.. when the weather cools l might contemplate reinstalling.. l must admit last install l was prolly trying to do too many things at once which might be the reason.. but back then l wanted to finish quickly because ld only just got my fibre connection and was downloading all the large things l had put off on my 2meg connection lol.

Backup SSD Image

If you decide to reinstall, you should create some backup SSD images.

Once you have reinstalled Windows and gotten the updates, but before you install any programs, you should create a backup SSD image.

Note:
If you don't like Windows Backup, you may need to install something like Macrium Reflect first.

IMO, you should create another image after you have installed your programs, before you start surfing the Internet.

Restoring a backup image on your PC (re-imaging) takes a lot less time than reinstalling everything.

I prefer to use Macrium Reflect.

l found it even quicker using a flash drive but then again you do have to take into account program installing as well :/

I'm confused.

It takes 7 minutes to restore my OS and programs from my backup HDD image.
It should be even quicker using an SSD.

It would take me all day (if not longer) to install Windows 7 (+ SP1 and the other updates), configure/customise it and install my software.
