computer slows down, as hidden (background) internet traffic continues

system · 2015-10-29T09:53:05.000Z

Hi,

I realised my computer slowing down, maybe after some hour or so. Even with only one program (e.g. internet) running, the CPU usage rises, up to 100%. When I checked the Windows Task Manger, I found several PROCESSES running in the background, namely Iexplore.exe, with higher (over 100k) memory usage. When closing them manually, they start to recover (but nothing to see on screen, just the message “Tab recovered”, and process appears again in the Task Manager).

After closing them all, and re-boot, and watching the Task Manager, I found that also here the iexplore.exe processes come up after some time by themselves.

I made a total scan (8 h) with my antivir software, but after that (and cleaning some viruses), it’s still the same situation.

Computer is rather old, but it’s in my Office, and very well adjusted to the work to be done, so I’d like to keep with it, and especially with that old IE 8:

Windows XP Professional, Version 5.1 (Build 2600.xpsp_sp3_qfe.130704-0421 : Service Pack 3)
IE 8

Could any one help me, please?
I downloaded the suggested files (MBAM etc.) already.

Thanks a lot. 8)

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)
Instructions: https://forum.avast.com/index.php?topic=53253.0

system · 2015-10-29T10:14:36.000Z

MBAM: “The application failed to initialize properly (0x000001.d) Click OK to terminate the application.” message appears.

the rest is attached.

OK, now you’ve to wait a bit…

Hi,

just a recent finding: When accessing e.g. a PDF document through a link, a new (empty) web page opens shortly, then the PDF is open. This is normal. But now, today (and I remember also in the last few days), this web page has some advertising for Windows 10 on it - which is not my home page, nor did I ever surfed there.

Maybe it helps?

Many thanks,
Lillebror. 8)

Hi,

& thanks a lot!

Attached 3 files
(…and there’s also a Quarantine.txt?)

essexboy · 2015-10-29T16:01:43.000Z

How is the computer now?

system · 2015-10-29T16:12:30.000Z

…appears to be faster now. There’s not that advertising page inbetween now, anymore.

system · 2015-10-29T16:22:22.000Z

Hi,

will the changes also affect the other issue (hidden background programs)?
Currently, there are two iexplore.exe running with only one open website…

Many thanks,
Lillebror.

system · 2015-10-29T17:26:13.000Z

Hi,

After one hour working now, there were 4x iexplore.exe running, 2 of them remain if program is closed. (Maybe it has to be this way?)

It seems to be faster, though.

I have to leave now, could continue tomorrow.

Really thanks again for the help here - very much appreciated!!

essexboy · 2015-10-29T17:30:27.000Z

Aye could you run a fresh FRST scan tomorrow so that I can ensure it has not returned

system · 2015-10-30T13:13:00.000Z

Hi,

here’s the FRST scan result…

…and my virus scanner made alert, see other txt.

essexboy · 2015-10-30T13:19:13.000Z

That does not appear to be running but we will remove it anyway

Hi,

that fixlog.txt is in my last post…

…and I was running again that FRST, and this time, it went thru, with frst.txt and addition.txt. Below are both log files.

…and I found this page newly in the HISTORY section of my browser (but wasn’t there):
“Windows and Windows 10 - Microsoft” !!!

Are you using a USB as you are infected again

system · 2015-10-30T16:23:21.000Z

Hi again,

many thanks for the help.

The ComboFix log file is attached.

What caused the issues? Solved/cleared? Shall I ran anything for checking?

essexboy · 2015-10-30T17:57:48.000Z

This appeared after the last clean which is why I asked about USB c:\documents and settings\user\kkbe1k.exe

system · 2015-11-09T11:47:57.000Z

Hi again,

(I was away for a week):

no, I don’t boot from USB, but do transfer data. Will check my USB sticks with MBAM (but from another computer, as it does not work here).

Computer seems to work very well now - no background things any more.

Thank you very much to all who helped me with it!!! Really good to know you’re here.
