Hi,
I keep getting block messages at start up.
I have followed logs post and attached logs (hopefully done it correctly). MBAM found several threats which I quarantined with the program.
Any help would be very much appreciated.
Could you attach a screenshot of the Avast popup

Save this as fixlist.txt, in the same location as FRST.exe

Thankyou for your help essexboy, much appreciated.
I followed your instructions and have attached FRST log and AdwCleaner log
I couldn’t post a screenshot of last popup as after reboot there isn’t any, and the pop-ups have stopped atm.
When I clicked like to post this reply, I got a message about changing search provider to bing - have posted screenshot - I don’t know what that’s about?
Thanks again
That may have been due to me removing an adware search provider search provider
Any further alerts
No, nothing at the moment - I always got an alert on start up, but that isn’t happening now
think its fixed?
Thanks again for your help
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:
Remove tools
Download and run Delfix

: Keep Java Updated :
WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)
If you do need to keep Java then download JavaRa
Run the programme and select Remove Java Runtime. Uninstall all versions of Java present
Once done then run it again and select Update Java runtime > Download and install Latest version

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
CryptoPrevent install this programme to lock down and prevent crypto ransome ware
https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG
Update and run weekly to keep your system clean
Click on the link above to be taken to Unchecky.com
click the very large Download button.
click Save
Click Open folder
Right click on the Unchecky_setup and choose to Run as Administrator
Once open click the Install button.
Then click on Finish
Unchecky is now installed and will help you keep unwanted check boxes unchecked, this is a fire and forget programme 
It is critical to have both a firewall and anti virus to protect your system and to keep them updated.

All seems good now, I just wanted to stop back and say thank you very much essexboy for all your help and advice. Great work.
Plenty of Kudos
My pleasure
