THEN

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

Morning essexboy ;D I have done as you requested, The computer is “Flying” it’s Fast, Crisp and Smooth! I ran a “Full Avast” scan and it was “No Errors Found” and all the other stuff is gone!

The latest FriOTL Scan and Combo fix Logs are attached.

If you can take a minute? Could you please tell me how long that “sirfef/zero access” virus has been on my PC, and what it actually does?
Thank you many times over for your time and for all you have done It is greatly appreciated, Cheers Cobba :slight_smile: Dasha

You have had this one since the first time Avast caught it and Avast has not allowed it to transmit any data

This is used for many purposes, stealing data, redirections and click to gain http://www.bbc.co.uk/news/technology-21860360

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Remove ComboFix
[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall
(Notice the space between the “x” and “/”)
then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif
Malwarebytes.

Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

If you use on-line banking then as an added layer of protection install Trusteer Rapport

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
[*]Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?Keep safe :wave:
