Windows Security Alert Virus

[mc_and_son]

Today, while browsing on the internet, a large window with red background popped up entitled "Windows Security Alert".  It said that that my PC had been infected by a virus, that private details were at risk, and that I must immediately call a toll free number to fix things.  It was accompanied by the same audio message.  I proceeded to do a full scan with Malwarebytes Premium and McAfee, but no threats were detected.  I'm using a PC running Windows 7 Professional.  The browser was Firefox.  Any help that the forum members can provide will be much appreciated. -  mc_and_son

Kevin - Thanks much for helping out.  I've followed the instructions in the "im-infected-now ..." link.  Attached are the FRST, Additions, and Malwarebytes Threat Scan log files that I generated.

Thanks for those logs, continue with the following:

Next,

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Download AdwCleaner by Malwarebytes onto your Desktop. Or from this Mirror   Right-click on AdwCleaner.exe and select Run as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users) Accept the EULA (I accept), then click on Scan Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Clean button. This will kill all the active processes Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply Next, Download Microsoft's " Malicious Software Removal Tool" and save direct to the desktop Ensure to get the correct version for your system.... https://www.microsoft.com/en-gb/download/malicious-software-removal-tool-details.aspx Right click on the Tool, select “Run as Administrator” the tool will expand to the options Window In the "Scan Type" window, select Quick Scan Perform a scan and Click Finish when the scan is done. Retrieve the MSRT log as follows, and post it in your next reply: 1) Select the Windows key and R key together to open the "Run" function 2) Type or Copy/Paste the following command to the "Run Line" and Press Enter: notepad c:\windows\debug\mrt.log The log will include log details for each time MSRT has run, we only need the most recent log by date and time....   Let me see those logs in your reply, also tell me if there are any remaining issues or concerns...   Thank you   Kevin...

Kevin - I've followed your instructions and have attached the resulting three log files.  I haven't noticed any issues, so do you think my PC is now malware/virus free?   And again, thanks for your help.  mc_and_son

Hello mc_and_son,

Yes your system is clean, run the following to clean up tools we may have used:

Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we may have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
