wouldn't have had a chance to be copied to the Root directory. I know that I have problems trying to save anything in there with UAC enabled.
2009 Virus:
I was researching for a possible answer to an unrelated question when this site popped up with possible suggestions so I clicked on the link. I was immediately presented with a Dialogue box offering to install AntiVirus2009 and I wasn't impressed that Avira didn't pick up on the two .cmd files that were inserted. I was a bit quick and didn't get the Registry command but I can imagine that it had something to do with the Run command.
spiritmythos@.org/blog/2/?t=7260667 I have deliberately modified this link so that no-one will inadvertantly copy it and run it. I stress again only run it in a test environment if you have to!
I was on my Vista PC with UAC disabled so I logged out and logged back in and ran MalWareBytes and these files were detected after clicking on the link. Avast didn't pick up on them.
Files Infected:
C:\clean.cmd (Trojan.Agent) -> Quarantined and deleted successfully.
C:\CHis.cmd (Trojan.Agent) -> Quarantined and deleted successfully.

That is the hook connecting to the sinker. So I got a bright idea, I would setup a test PC with no Antivirus to see how MalWareBytes performed. It was installed and updated. I then copied the link into IE7 and clicked search without putting in www. and I then had to coax the Virus to install. It wouldn't let me save the file that it wanted to download as it would corrupt and leave off the extension .exe. It was happy enough to let me install by clicking on Run. Just to make sure that it felt as though it was home I did a restart of the PC and sure enough it was loaded in the TaskBar. I even tried a Scan and it magically found a few Viruses and then the NAGS began. Surprisingly though I was able to close them out.
I then ran MalWareBytes and it detected and removed this:

I tried to run BitDefender but maybe I have ran it too many times as it wouldn't load for me. It couldn't update the Scan Engine. So I decided to give TREND micro a go and it has found SPYWARE_KEYL_ACTIVEKEY which can also be interpreted as Type: Spyware
Aliases: PAK:PEData (BitDefendr); Active Key Logger 3.0 (PestPatrol) I couldn't get any sense out of TREND micro's scan so I left them to it. It obviously found BitDefender which adds itself to the Registry.
I am now running KASPERSKY to see what it will find. It didn't find anything so I decided to install Avast Antivirus and let it install. It went along quite happily and Updated itself. It did a Scan but didn't find anything. So I did another trip to the infected site and ran the setup again but Avast seemed to block it afer it was supposedly installed. But on a rescan with Avast I have found another Virus. Fake Alert which was deleted. I then tried to shutdown the PC but until I did a Crtl+Alt+Del and checked for anything unfamiliar which didn't appear to be there it wouldn't shut down. I did a restart and turned the PC off. To be continued...............
Ran MalWareBytes and Avast again and it came up clean. Obviously MalWareBytes does a good job but it needs a bit of help.
