Hello again.
Thanks for that advice.
I suppose I should have mentioned in my previous post that I'm running Windows X.P. with Service Pack 3, with Windows Firewall (though I'm considering trying Zonealarm)
My internet connection now appears to be behaving more normally, so it seems like Malwarebytes may have cured the problem.
Anyhow, dealing with this in order:
A-squared is an antivirus and antispyware, but, in its' free form, it is purely an on-demand scanner; I assume, therefore, that it is inert unless I activate it. I've not noticed any apparent conflict with A.V.G.
I scanned with MBAM as instructed. It found two items, deleted one immediately, and the other on re-boot. I then re-scanned, but it again found one item; it occurred to me to turn off System Restore. The item found was the same as the one found in the first scan to be deleted on reboot. I rebooted again and the third scan was clear.
Therefore there are 3 MBAM logs, as follows (I've replaced my name as it appears in the first log with the words "name-edit"):

I re-started "System Restore" prior to proceeding with ATF and Super.
ATF removed a fair amount of... whatever it was...
Super has found no infection. I took your post to mean that I should "complete scan" purely with "Close browsers before scanning", "Scan for tracking cookies", and "Terminate memory threats before quarantining" checked, and therefore I unchecked everything else.
The "Super" log is as follows:

I hope that this makes sense.
Thanks again.
