Dear,
As others I recently started to get pop ups from Avast every time I use my web browser indicating that the avast web shield has blocked a harmful webpage or file indicating it is related with opticized.net and the process svchost.exe.
In some other threads people attach some logs but I do no know whic ones, how to get them and how to post them.
Please indicate how to proceed.
Thanks in advanced for your help

attach Malwarebytes and Farbar Recovery Scan Tool logs
Dear Pondus,
Thanks for your support. Attached requested logs.
Do the Malwarebytes actions solve the issue?
Regards
maybe … log experts will see that from Farbar diagnostic logs when they arrive, it may take some hours before they are online
Hi you still have Norton running on the system , I would recommend that you uninstall it
CAUTION : This fix is only valid for this specific machine, using it on another may break your computer
Open notepad and copy/paste the text in the quotebox below into it:
EmptyTemp: CMD: bitsadmin /reset /allusers
Save this as fixlist.txt, in the same location as FRST.exe
Run FRST and press Fix
On completion a log will be generated please post that
THEN
Please download AdwCleaner by Xplode onto your desktop.
[*]Close all open programs and internet browsers.
[*]Double click on AdwCleaner.exe to run the tool.
[*]Click on Scan.
[*]After the scan is complete click on “Clean”
[*]Confirm each time with Ok.
[*]Your computer will be rebooted automatically. A text file will open after the restart.
[*]Please post the content of that logfile with your next answer.
[*]You can find the logfile at C:\AdwCleaner[S1].txt as well.

Dear essexboy and Pondus,
Thanks for your help and support.
Attached the two new logs.
In the meantime I will look into the Norton removal
Cheers
Could you confirm the alerts have now ceased
Yes, apparently the alerts hace stopped.
Norton products uninstalled too.
Many Thanks!!
In that case methinks I will send you on your merry way 
Subject to no further problems
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 
A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:
Download and run Delfix
