Something called Antivirus System Pro has gotten into my PC. How
can I remove it.
I can't run my FREE AVG to get rid of it. It may have happened when
a popup from Quicktime asked me to upgrade. I'll never trust that
again.
Assuming Windows XP 32-bit...
Fix your file/registry permissions...
Ignore the title and follow the sub-section under "Advanced Troubleshooting"
titled, "Method 1: Reset the registry and the file permissions"

(** Ignore the last step - you should install SP3 if you don't have it
- but not at this point in the cleanup/repair.)
Reboot and ...
Search your registry for %fystem and replace the "f" with an "s". May be
three or four matches, may be none. You may even have to take ownership
(even after doing the above) of the keys in order to make the change.
Reboot and ...

After installing, do the following:
Start button --> RUN --> type in:
"%ProgramFiles%\Windows Installer Clean Up\msizap.exe" g!
--> Click OK.

Download, install, run, update and perform a full scan (separately) with the
following two applications (freeware versions are the ones to use for this):
SuperAntiSpyware
http://www.superantispyware.com/
MalwareBytes
http://www.malwarebytes.com/
After performing a full scan with one and then the other and removing
whatever they both find completely, you may uninstall these products,
if you wish.

Ensure your hardware drivers are up to date (from the hardware
manufacturer's respective web pages.) Never get hardware drivers
for hardware that was not created/sold by Microsoft from Microsoft.
Installing the latest updates may have you rebooting several times,
which is fine - but after you are sure you are done - still...
Reboot.
Download/Install the latest Windows Installer (for your OS):
( Windows XP 32-bit : WindowsXP-KB942288-v3-x86.exe )
http://www.microsoft.com/downloadS/...6F-60B6-4412-95B9-54D056D6F9F4&displaylang=en
Reboot.
and...
Download the latest version of the Windows Update agent from here (x86):
http://go.microsoft.com/fwlink/?LinkID=91237
.... and save it to the root of your C:\ drive. After saving it to the root
of the C:\ drive, do the following:
Close all Internet Explorer windows and other applications.
Start button --> RUN and type in:
%SystemDrive%\windowsupdateagent30-x86.exe /WUFORCE
--> Click OK.
(If asked, select "Run.) --> Click on NEXT --> Select "I agree" and click on
NEXT --> When it finishes installing, click on "Finish"...
Reboot.
Then follow the instructions here:
How do I reset Windows Update components?
http://support.microsoft.com/kb/971058
Reboot.
Log on as an user with administrative rights and open Internet Explorer
and visit
http://windowsupdate.microsoft.com/ and select to do a
CUSTOM scan...
Every time you are about to click on something while at these web pages -
first press and hold down the CTRL key while you click on it. You can
release the CTRL key after clicking each time.
Once the scan is done, select just _ONE_ of the high priority updates
(deselect any others) and install it.
Reboot again.
If it did work - try the web page again - selecting no more than 3-5 at a
time. Rebooting as needed.
The Optional Software updates are generally safe - although I recommend
against the "Windows Search" one and any of the "Office Live" ones or
"Windows Live" ones for now. I would completely avoid the
Optional Hardware updates. Also - I do not see any urgent need to install
Internet Explorer 8 at this time.
Seriously - do all that. This is like antibiotics - don't skip a single
step, don't quit because you think things will be okay now - go through
until the end, until you have done everything given in the order given. If
you have a problem with a step come ask and let someone here get you
through that step. If you don't understand how to do a step, come back and
ask here about that step and let someone walk you through it.
In any case - no matter what - when you are done doing whatever you decide
to do - please - come back here and let everyone know what you did and
how things turned out.
