(Solved) Desktop pc suddenly slow
Lady:
BullGuard and MBAM both perform real-time protection, on browsing and e-mail. MBAM daily performs a threat scan. BG has a few daily backup tasks to the external HDs. And I have MBAM Anti-Exploit. With a new slow-attack I can check if they're active. But if these real-time actions are interfering I would have had these slow-attacks all along (some days I spend a LOT of hours on the pc continuously) and I haven't had these serious problems with slowness before. I know the pc to be slow sometimes with opening new programs e.g. and then I often hear the pc case give starting-up sounds as if it were asleep (sleep options are off).
The paging file is set to auto-manage.
I saw DEP being set for all programmes and services (as somebody told me to). Is that correct? I have so much protection already. And the EMET error message on Word said something about DEP mitigation. Is that connected?
I decided to bring the number of tabs down. But for that I need more time which I have not at the moment. :S
Slowness in its worst form is waiting up to a minute with every mouse click. Even in Explorer or MusicBee or Word or wherever. Whatever its degree of slowness, it's with every program or function. I think I also tried shutting Firefox down to "make space", but to no avail. Up till now I have not detected any pattern. But then I have to check it in a more structured way, noting down time and checking all possible causes.
The bandwith is another very good idea of yours! I use a LAN cable (ADSL). Right now without any slowness problems my download speed is 12.99 (I pay for 20 Mb but I understand from my provider that I'm further away from the transmitting station). Upload is 0.83. I can check the speed when under attack. :smiley: Years ago I checked the download speed and it was about 13 at the time too. I have had no problems with such a seemingly low download speed. Especially since I blocked the trackers, downloading sites is very fast. At least fast enough for me. With uploading also no problems. I can wait, am a patient person. :smiley:
Could you comment on my last two paragraphs of my last post about IE and Windows Repair?
Thank you for putting in some much of your time and your brain energy! Thumbs up again!

Didn't you have this discussion with Shane before about you having Dynamic disks and wasn't a fix suggested to convert them ?
Can't remember now if they were a problem with WR.
I'm not sure about IE shutting down with just one particular site - have you tried running IE in Compatibility Mode ?
It could be a fault with the site itself and contacting whoever to report that problem may cough up something.
Usually resetting IE to defaults can resolve some problems, but when it is site specific, then it could be the site itself.
Changing your DNS servers to something like Google's 8.8.8.8 / 8.8.4.4 may help if your current DNS servers have problems resolving its address and resetting the winsock may also help, but if it was the winsock, then I would expect you to have other browsing problems.
To reset the winsock, run a cmd prompt as an admin and enter netsh winsock reset catalog and then shutdown /r /t 00 to effect an immediate reboot.
I don't think it will be a TLS problem, but SSL should no longer be used although depending upon the website, you may need to check the box for Use SSL 3.0 as well as all of the TLS boxes.
They are in IE - Tools - Internet options under the Advanced tab then scroll down to the Security section.
I can't think of anything else for that at the moment other than also in IE - Tools etc. under the Content tab click on Clear SSL state.

We talked about changing the dynamic discs to standard using Minitool Partition Wizard or some other program but I was advised not to mess with them if the pc was doing okay.
I wouldn't think a WR would act differently if the discs were dynamic. What are the possible risks of doing a WR? And does a system restore point work if anything after a WR is totally off?
I cannot open IE at all. That's what got me thinking about a WR again. Maybe some files have become corrupted again and maybe hence the slowness??
I don't want to put a lot more energy into this. Let's drop the slowness issue for now. A re-installation is the No. 1 solution, also regarding the discs, but I really can't have that now.

Not being able to open IE at all could be a winsock problem but go Start - All Programs - Accessories - System Tools - Internet Explorer (No Add-ons)
Or you could go Start - type iexplore -extoff and press enter.
When it opens, click on the home page icon and then see if you can browse - btw which browser are you using now ?
If you can then browse, you may have picked up adware.
Resetting IE to defaults can get rid of most add-ons but download and run AdwCleaner followed by Junkware Removal Tool -
https://toolslib.net/downloads/viewdownload/1-adwcleaner/
https://www.malwarebytes.org/junkwareremovaltool/
Don't know if you've used AdwCleaner before but click on Scan and when it has completed, click on Report - during the scan it may pick up other programs it considers as adware and will list those in the lower pane - which you can uncheck before clicking on Report.
The report will list whatever it will delete when you close the report and click on Cleaning, then after the reboot will open another report to show what it has deleted.

Both times, as with my own efforts, IE opens but it says "not responding" and the waiting symbol is there for about 20 seconds and then it all disappears.
The slow attack is back since I returned to my pc an hour ago. Today in the afternoon all was fine. I kept the pc running with the monitor off after a minute. I just now checked the bandwith speed: 13.02, so no problem there. My AV/Malware family is doing nothing as far as I can see.
See attachments for the Task Manager at this moment. In 2a it is interesting to see that I have a lot more free memory now. I guess that's because I closed Firefox just now so that BullGuard could delete the Firefox cache for its Optimalisation feature and after that I didn't open a lot of tabs. In 2b you can see a lot lower figure for Firefox right now (before it was 400.000). I haven't closed any more tabs. And still the pc is slow. Not on every mouse click or keyboard touch, but still, very annoying.
If you're online now on Saturday evening :smiley: and while I'm under attack, could you suggest anything else I can check? I'll be online for another hour or so.
