Avast keeps notifying me of a Malware block but scans come out clean

Updating your passwords would not be a bad idea; there is no way to tell for sure now if your passwords were accessed or not but better safe than sorry.


Please monitor the system for a day or so and let us know how it is.  If fine we will remove our tools and get you on your way.

Bad news. Just got another ping from Avast, same as original.

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.
Running it on another one may cause damage and render the system unstable.

Download attached fixlist.txt file and save it to the Desktop:

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

• Right-click on icon and select 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.

How is the system now?

Log is attached. Haven't had any popups but will update if I do.

Day 2 of using the computer and nothing has popped up, we seem to be in the clear. Could you tell me what it was that was giving me trouble? Not sure what was in that fixlog file but it seems to have worked. Thanks!

The malware used the standard Internet Search setting to store a malicious link on your system.  Nothing wrong with what it did except for the actual link address to a known bad site.



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:
  
• Create registry backup
• Purge system restore

• 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 ==

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 uBlock Origin add-ons to the browser to block scripting hijacks and remove unwanted ads from the pages you view.
