Pushdo Trojan? Same as HackTool.ADRN?

I clicked on a certain link this morning and received this message:
Access has been blocked.
Your IP [190.233.117.82] is found at Spamhaus .
If you feel this is incorrect please contact them.

So I visited Spamhaus and this is what I found:

http://www.spamhaus.org/query/ip/190.233.117.82
The first red link on the above page says my machine is sending emails.
The second red link on the above page says :
IP Address 190.233.117.82 is listed in the CBL. It appears to be infected with a spam sending trojan, proxy or some other form of botnet.

It was last detected at 2013-06-14 00:00 GMT (+/- 30 minutes), approximately 1 days, 13 hours, 30 minutes ago.

This IP address is infected with, or is NATting for a machine infected with Pushdo. Pushdo is a DDOS trojan - meaning that it was (at least of the timestamp given above) participating in a HTTP-based (web protocol) distributed denial of service attack on web server[s].

Pushdo is usually associated with the Cutwail spam trojan, as part of a Zeus or Spyeye botnet. Together, this provides the attacker with DDOS, email spam, and information theft capabilities. This is something you really want to get rid of. But remember, we detected this specifically by the DDOS traffic to a web server.

And it gives this as a reference link:
http://www.theregister.co.uk/2012/09/19/pushdo_spews_fake_traffic/

I just ran a full scan with AVG. (My last scan was 2 days ago.) The new scan found and removed an infection (in 4 files), but it did't call it Pushdo trojan. It is HackTool.ADRN. Same thing, or am I still infected with Pushdo?

These two infections are different.

To make sure, run malwarebytes antimalware (free) and TDSSKiller.

Or, restore your PC to a date before the infections.

Malwarebytes found the following and removed it:

Registry Data Items Detected: 1
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced|StartMenuLogoff (PUM.Hijack.StartMenu) -> Bad: (1) Good: (0) -> No action taken.

TDSSKiller found nothing.

I don't know long I've been infected, so wouldn't know how far back to restore my PC.

Well, create a restore point at this point in time.

And, keep using your PC, which seems to be clean now, until you notice any undesirable occurrences.

One note, however:  Just check in the list of installed programs, any that you don't recognize; uninstall or disable form starting up any that you don't recognize. Inspect also all start up programs.  Thanks.

You say my PC seems to be clean now, but nothing yet has detected Pushdo, which supposedly was on my machine less than 2 days ago.  As far as I can tell, PUM.Hijack.StartMenu isn't the same as Pushdo.

Note: In many cases, a PUM, Potentially Unwanted Modification, is a false positive.

Now I've run SpyHunter which found 2 different malware toolbars that weren't found by AVG or MalwareBytes. But I still haven't been able to detect Pushdo which must still be on here.

Everything I'm reading online tells me that Pushdo is very hard to detect but I'd really like to find a program that can detect Pushdo's presence before I restore to an earlier point so I can check that it's really gone after the restore.

I've set up Windows Firewall to log all connections, I might be able to use that to detect traffic from Pushdo by looking for connections made when I'm not using the internet.

Make sure your AVG is updated and running all the time.

If you see pushdo come back, use Kaspersky Rescuedisk (to boot from, scan, and clean).
