Avast Web Shield keeps reporting blocked URL

Viruses and worms
1

Hi,

I have a windows 7 laptop running Avast and it keeps displaying messages that it blocked a harmful webpage or file. When the messages pop up I am not even using my browser. It says (Infection URL:MAL and process = c:\Windows\syswow64\dllhost.exe . It appears to be trying to connect to some web site like fff5ee.com and then a bunch of other stuff after that. Here is what I have done so far to try and fix it:

  1. Ran Avast full system scan
  2. Ran Malwarebytes
  3. performed a system restore to a date I thought was good and then did number 1 and 2 again.
  4. Ran AdwCleaner
  5. Ran spybot Search and Destroy

After running all these programs and cleaning what they found I am still getting the webshield pop up. At this point I am not sure what else to do to correct this problem. Any assistance you could provide me would be appreciated.

Thanks,
David

Essexboy,

That took a while to run but it finally finished. I have attached the log. Things appear to look better now. Would you mind sharing with me what you saw? Thank you so much for the help. You have been AWESOME!

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 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.
