Security warning malware

[Robert]

My computer was hit with a security warning malware today. This according
to searching this group. I am a novice with this sort of thing. Now I get
a popup whenever I try to run a program. Internet Explorer will open but
when I put in a site I get a screen saying it can't open the site and to
purchase some software. In another post I see a link to
download.com/Malawarebytes-Anti-Malware/3000-8022_4-10804572.html. The
problem is I can't go into the sight due to this screen. So what can I do?
Can I download the tool on another computer (the one I'm using right now)
and put it on the infected one? Or should I do a system restore? Or am I
completely off the track? Suggestions welcome.

Using Windows XP Pro.
Excuse if a second post. Not intentional.

The second "a" doesn't belong in the address above; it should be:

download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html as in
MALicious softWAREBYTES.

You can either:

- remove the hard drive, insert in another machine, and scan it using
that machine's a/v software.

- Boot to Safe Mode and hope you can download, install, update and run
Malwarebytes from there.  That's doubtful; there's usually an error if
you try to do all that from Safe Mode.

or

- Download this Avira Antivir Rescue System program which will burn a CD
image to a blank CD.  It's updated a few times per day.  Insert the CD
into the damaged machine and let it do a scan of your system.  Before
starting the scan, select "Configuration" and set to repair or rename
the infected files.  Sometimes your machine won't restart after such a
repair process, so you might want to save needed files to another system
before using this.  If you can't, then you can move the hard drive to
another machine to copy needed files.  You can do that before, or after
this scan.

Then run these:

Malwarebytes© Corporationhttp://www.malwarebytes.org/mbam/program/mbam-setup.exe

SuperAntispywarehttp://www.superantispyware.com/superantispywarefreevspro..html

AVG now has a Rescue CD that's free.  They also have a free USB download
that should work on newer systems that can boot from a USB device.  Get
them here:

You can try some of the CD's mentioned at the following site.
BitDefender was my favorite, but if the infected machine can't connect
to the internet to get updates, Avira comes with current virus
definitions.  Also, some of these just won't run on some systems,
perhaps because there's no drivers available for some system devices,
motherboard, graphics card, etc.  So try a few of these till you find
one that works:

Burn BitDefender, or another program listed at the link below, to a CD
(using a working machine) and test the infected machine with it.
BitDefender also has a Rootkit checker on the Linux Desktop; run it if
you think that's the problem:

Download the executable rather than the .iso image, if one is available,
(though no .exe is available for BitDefender).

After the scan is run, if you elect to quarantine files, they're
quarantined to RAM and lost after you reboot.  You'll need to copy any
quarantined files to the hard drive, a thumb drive or elsewhere before
exiting.

Robert, try using a small program called rkill. It will stop the
malware process from running so that you can run your cleaning
software. Read here: http://www.bleepingcomputer.com/virus-removal/remove-security-tool
Good luck
