A lot of people in this forum seem to be having a similar issue. For the last day and a half or so, my computer has been getting constant alerts from the Avast! Web Shield telling me that malicious URLs have been blocked. The alerts tell me that different URLs have been blocked each time. I’ve unplugged the ethernet cable from my computer, so it is not currently connected to the internet. Most of the alerts that I’m given also seem to be coming from the iexplorer.exe file, though I’ve been unable to locate that file, and I do not ever use Internet Explorer. I will be posting the necessary logs shortly. If any other information needs to be supplied, let me know and I’ll see what I can do. Any help would be greatly appreciated. Thank you!
I’ve attached the logs from MBAM and FRST, and I am currently running aswMBR, though it seems to be hung up on a file, and it’s not making any progress. I’ve also included an image from one of the alerts for reference.
It is also worth noting that The reference image is not representative of all of the alerts I have been getting; many of the alerts have said Mal instead of Iframe-inf.
The aswMBR scan finished. The logs are attached.
I still need help with this whenever possible, so bumping.
Let me know if this stops it

The Fixlog from FRST and the logs from adwCleaner are attached. This appears to have solved my problem! I haven’t gotten any Web Shield alerts after a few hours of normal internet usage. Is there anything else I should do before calling it good?
Woops, here are the logs.
Nope, that looks good
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

: 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
