How did this Trojan appear?

[wrkg_onit@yahoo.com]

My system configuration: Win XP SP2 with all updates, firewall on,
behind a router. AVG anti-virus. At the time of the incident I had
several Opera browser windows open, and pointed to respectable
financial sites like finance.yahoo. Outlook Express was loaded and may
or may not have been downloading email. Microsoft Excel was the only
other user application running.

What happened was AVG suddenly reported an attempt by "Trojan horse
downloader Zlob.ABQ" to load into one of my system restore
subdirectories. How can this happen without me clicking on an
attachment or popup, etc.?

Zlob usually installs when you click on a fake message prompting you to
download a new Codec or ActiveX Control to view a video cf.

Such infections are usually accompanied by Vundo and SDBot infections these
days.

No anti-virus application can protect you from all hijackware, and AVG is
the worst-performing AV app of the lot.

Run a /thorough/ check for hijackware, including posting your hijackthis log
to an appropriate forum.

When all else fails, HijackThis v2.0.2
(http://aumha.org/downloads/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware with
assistance from an expert. **Post your log to

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.

One possibility for a ZLob Trojan...
You visited some video site. Maybe a p0rno video site. When you went there it indicated
that to play the video you needed to install a Video Codec or Video ActiveX whicgh it was
neither. It was a ZLob.

Please provide more specific information such as the fully qualified name and path to the
file deemed infected with the ZLob Trojan.
