Avast notifies me it has blocked a harmful webpage every time I open a new page

[fivetimesredmen]

Hoping someone can help me with this because it's driving me nuts.

New laptop running windows 8 and thought I would give avast a try after always using Norton. Two days ago the pop up and voice started every time I open a new tab or even change page on a site. It says:

object:  http://...?id=2004703bro=CH

infection: URL:Mal

I've installed Malwarebytes and performed a quick scan which removed 6 objects but no change to the constant pop up. Any advice would be greatly appreciated as would your patience because I'm not the most computer literate person around so step by step instructions will be needed.

Follow the steps here http://forum.avast.com/index.php?topic=53253.0

And attach the logs in this thread

I've tried to attach both logs, mbam and OTL (there was only one OTL saved). Any probs and I'll try again

[essexboy]

Could you attach the OTL log please

[fivetimesredmen]

Sorry having trouble making posts

Sorry this log was also here (windows 8 is killing me) Hope this is everything, apologies for the delays.

OK first we will remove McAfee and Norton.

I see that you are using Poki for the start button, have a look at classic shell as that is much better  http://www.classicshell.net/

Download these two removal programmes to the desktop :


http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

From Control Panel > Programmes and Features uninstall :

Any Norton product
Any Symantec product
Any McAfee product

On completion run the two removal tools one after the other.  A reboot may be required in between

NEXT

Run OTL

Please download Junkware Removal Tool to your desktop.

• Right-mouse click JRT.exe and select "Run as Administrator" the tool will open and start scanning your system

• On completion, a log (JRT.txt) is saved to your desktop and will automatically open.

Heres the JRT.txt as requested

I've followed your instructions and the problem with the constant pop up has gone.

Can't thank you enough mate not just for getting the pop up to stop but for giving me the classicshell button. Not having a start button is what I hate most about windows 8 so again thanks a million

Run OTL and press the cleanup button, delete JRT from the desktop

Keep safe
