Dear TwinHeadedEagle,
Attached, you should find a copy of fixlog.txt as requested.

Panda Antivirus was the programme that allowed the malware through in the first place. I turned it off once I had successfully installed Avast. I have now uninstalled it as requested.

After rebooting, the home page for internet explorer changed from google to:

 http://www.msn.com/en-ae/?ocid=iehp

Avast became inaccessible in internet explorer. There was a message:

 Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://forum.avast.com again. If this error persists, contact your site administrator.

I did this, but found that they were already turned on. I have therefore re-opened IE and I hope am now able to communicate.

Thanks for continuing this process. Do let me know what I should do next!

How is your PC behaving now? It seems clean.

Dear TwinHeadedEagle,
Many thanks for the fix.

At first, everything seemed fine with my external hard drive, but now it has started disappearing (from Windows Explorer), then reappearing again (after an MCShield scan – which says that it’s clean each time).

The external hard drive didn’t behave like this on the other computer, yesterday. The timing resembles that of its previous behaviour on my computer (when it became inaccessible).

Notwithstanding the drive’s coming and going, Avast managed to scan it and found no malware – although it was unable to scan a large number of files.

Did you try to plug you external drive into different slot.

Dear TwinHeadedEagle,
I’ve just tried it now. Exactly the same behaviour:

External hard drive plugged in.

Appears on Windows Explorer.

Short while later (~3 minutes), disappears.

MCShield scan (all clear, drive G:)

Reappears (1 minute later)

Repeats ad infinitum (I imagine)

If the timing’s important, I can check.

I really don’t know what is going on, but I think it is some malfunction with your external drive. My hands are tied further, i cannot help you.

Dear TwinHeadedEagle,
Thanks for the message. I’m sorry to hear that your hands are tied and that you cannot help me further. I recognize that you’ve helped me significantly – for which many thanks! – but I am pretty sure that my computer is still infected with malware.

I certainly don’t think that my external hard drive is malfunctioning hardware-wise as you suggest, as it works perfectly with a different computer.

I am of course, very disappointed that Avast isn’t able to detect the malware on my computer.

I guess I’ll just have to delve further into the realms of malwarfare until I can find someone who is able to address the problem. If you have any suggestions of where to look, I’d be very grateful…

One additional bit of information: I took a memory stick with files from my computer (on which it appears to work perfectly – no shortcuts, no viruses according to Avast) to another computer today (to print out a document), and discovered that the memory stick was full of shortcuts that I certainly hadn’t put there intentionally…

Do you have MCShield running on this PC?

Yes: you (reply #14) and Michael (reply #12) told me to install it at the bottom of p1 of this thread.

Thanks, once again, TwinHeadedEagle. Attached, you should find fixlog.txt, as requested. Let me know what I should do next. I tried copying some files onto my external hard drive last night. It transferred the files rather slowly (~1Mb per sec), but did not disappear or become inaccessible…

Good. Keep me updated, PC is clean.

Hi, TwinHeadedEagle,
This is an attempt to keep you updated.

I’m glad to say that my computer appears to have stopped filling up external drives with spurious links and shortcuts.
However, it’s slow, sometimes very slow. It speeds up briefly, after cleaning, but it’s as if there’s something that quickly clogs up the memory.

Might it be something to do with the following?
• C:\Windows\SysWOW64\wpcmig.dll
• C:\Windows\SysWOW64\wpcumi.dll
They always appear as ‘Broken CLSIDs’ when I clean the Registry.

Svchost.exe is often the process taking up the largest part of the memory (from time to time – when things are bad) and the relevant Services Group is usually ‘netsvcs’ or ‘LocalSystemNetworkRestricted’.

Anyway, I attach two files, the results of scanning with Farbar Recovery Scan Tool.

Avast is running as is MCShield: neither has sent any warning signals.

Best wishes, and thanks for your help.
