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.?

So How Did I Get Infected Anyway?

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.

http://msmvps.com/blogs/hostsnews/default.aspx

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.
