Avast web shield keeps blocking harmful webpage or file

Hi all, I’ve had a problem since yesterday in that Web Shield keeps spamming me with notifications when I’m connected to the internet (don’t even need to go onto a browser)… I tried opening task manager and I saw HEAPS of advertisements accidentally and my computer can’t really handle all the ads or notifications so it keeps crashing (and the display driver keeps crashing too)…

Any help would be GREATLY appreciated, here’s my MWBAM scan log and my other logs, thank you very much.

Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:
It would be best if you move FRST64.exe to the Desktop also (we will clean these up later).

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

- Right-click on 

https://sites.google.com/site/cannedfixes/farbar-recovery-scan-tool/FRST.gif
icon and select
https://sites.google.com/site/cannedfixes/home/hosted-images-tools/RunAsAdmin.jpg
Run as Administrator to start the tool.
(XP users click run after receipt of Windows Security Warning - Open File).
- Press the Fix button just once and wait.
- If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
- When finished FRST will generate a log on the Desktop, called Fixlog.txt.
Please attach it to your reply.

I really appreciate your quick reply and help, here are the logs

Thank you!

Malwarebytes’ Anti-Malware
Please start MalwareBytes’ Anti-Malware from either the Start menu short cut or your Desktop shortcut (if you have one).

When the main screen opens, if the database is out of date, you can click on the Fix Now banner or the Update Now link

http://i1351.photobucket.com/albums/p785/dbreeze2/MBAM2_0/v2-1-4-1018/Main%20Screen_zpsnnwza0ky.png

Once updated, please select Settings > Detection and Protection. Please ensure that “Scan for Rootkits” is selected along with Non-Malware Protection PUP and PUM are set to “Treat detections as malware”

http://i1351.photobucket.com/albums/p785/dbreeze2/MBAM2_0/v2-1-4-1018/Detection%20Settings_zpsaviydqil.png

Once the program has loaded and updated, select “Scan Now >>” to start the scan.

http://i1351.photobucket.com/albums/p785/dbreeze2/MBAM2_0/v2-1-4-1018/Main%20Screen_zpsnnwza0ky.png

The scan may take some time to finish, so please be patient.

http://i1351.photobucket.com/albums/p785/dbreeze2/MBAM2_0/v2-1-4-1018/mbam21-scaninprogress_zps38w26yvt.jpg

If any malware is found, you will be presented with a screen like the one below.

Please click on the Export Log button and select the As text file from the dropdown list. I would suggest you save the file on your desktop (as we need the report attached here for review and it is easy to find on the desktop).

After you have saved the report file, return to the Potential Threats Detected page and click on Cancel. You can close MBAM after that.

Please attach the report file to a post here; I will review the file and script what needs to be removed.

Yay I think you did it! Everything looks good :smiley: Thank you SO much for your help.

If everything else if fine for you (Avast is running / scanning with no warnings, etc.) then I will remove our tools and get you on your way …

Clean up of Malware Removal Tools
Now that we are through using these tools, let’s clean them off your system so that should you ever need to have malware removed again (we hope not) fresh, updated copies will be downloaded.

  • Download Delfix from here to your desktop and double click it to start the program
    • Ensure Remove disinfection tools is ticked
      Also tick:
    • Activate UAC
    • Create registry backup
    • Purge system restore
    • Reset system settings

http://i1351.photobucket.com/albums/p785/dbreeze2/just%20stuff/DelFixSelectall_zps0f04cec4.png

  • Click Run
    • The program will run for a few moments and then notepad will open with a log. Note: Please save this log first before rebooting your system (if asked to); DelFix does not save the log as it is trying to remove all traces of our work on your system. Please attach the log in your next reply.
      You can delete any log files left on your desktop as these are no longer needed.

==Some Tools to consider to help keep your system safe ==

Consider a program that will check for out-of-date programs on your system
Some programs don’t have update checks built in or make you run the application to start the check for updates process. An easier way to stay on top of the current versions of your installed programs is to use a version checking program like Heimdal Free from Heimdal Security (you can get the software from here and read more about it on the same page).

Unchecky is a small service that runs in the background to help keep those “extra toolbars” and tag along search engines from automatically installing. By automatically directing you to a custom install with all the options unchecked, only what you manually choose and confirm gets installed.

CryptoPrevent is a free program that prevents CryptoLocker / ransomware from infecting your PC by locking down the OS so the malware can not get a grip on your system. You can read the details about this program here.

Also, consider keeping MalwareBytes Antimalware in your arsenal of safe keeping programs. Use the free version (not the paid or trial version) and you won’t have a problem with your antivirus scanner program. Keep it updated and run a scan with it once a week.

Lastly, if you use Firefox as your main web browser, consider adding the NoScript and AdBlockPlus add-ons to the browser to block scripting hijacks and remove unwanted ads from the pages you view.

I’ll leave this topic open for a few days so that if you have any questions you can come back here. Surf safe, my friend!!

Thank you so much, I really appreciate everything you’ve done. I downloaded some of your recommendations and hopefully I never have to bug you again!
