Avast Web Shield has blocked a harmful webpage or file.
« on: February 24, 2015, 04:27:28 AM »
Attached is a screenshot of the Avast popup warning and the MBAM log.  MBAM didn't find anything.  The object changes but everything else stays the same.

Other log files to follow.

Thanks

So far so good.  Thank you.  Do you know what it was specifically?  Any way to prevent it in the future?  If it happens again do I need to do this same process?

Much appreciated.

Chrome was changed to developer mode which is about as insecure as you can get

The main bad boy was a BITs task

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  :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 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



Malwarebytes.

Update and run weekly to keep your system clean

Unchecky

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.
