Just to clarify your system:
1. You are using Avast Pro (paid), you think you have the most current version but not the latest definitions.
2. You are not current with your MS Updates?
3. What do you use for a FW? Windows FW, third-party FW, or nothing?
Where you using Google at the time you got the splash screen alert?
We will need you go use the machine that is having the problem. I will need you to install Malwarebytes’ Anti-Malware (
MBAM) to do an initial check for malware. Please print these instructions, then download it onto the (possibly) infected machine:
· Download
free http://www.malwarebytes.org/ for an on-demand scanner.
· Double Click mbam-setup.exe to install the application.
· After install, click
update so you have latest database before scanning.
· Under Settings:
o
General: Automatically Save File After Scan Completes is checked off
o
Scanner Settings:
Check all boxeso
Updater: Download and install update if available is checked off
· Once the program has loaded, select "Perform
FULL Scan", then click Scan.
· The scan may take some time to finish, so please be patient.
· When the disinfection scan is complete, a log will appear in Notepad and you may be prompted to Restart. (See Extra Note).
· Click the “
remove selected” button to
quarantine anything found. You will find the infection details under the Quarantine tab.
· The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
·
Copy & Paste the entire report in your next reply.
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts -- Click OK to either and let MBAM proceed with the disinfection process; If asked to restart the computer, please do so immediately.
After doing this, use you unaffected machine to post while I review your MBAM log. Do you have any questions?
