Hello! I’m new to posting so if I’m not following a standard protocol, please correct me/link where the rules are so that I can comply.
Every 20 minutes or so, Avast is popping up telling me that a threat has been detected, specifically
Threat detected - s.vb3k.com/crossdomain.xml
I’ve run a full scan with Avast and no malware was found. I’ve seen a couple other postings with the same problem, but noted that the fix was computer specific.
Any help would be greatly appreciated!
see instructions here https://forum.avast.com/index.php?topic=53253.0
run Malwarebytes and Farbar Recovery Scan Tool as instructed, then attach the logs
Thank you! I’m attaching the MBAM and Farbar logs.
Now you wait for a malware expert to take a look … it may take some time, be patient
Could you let me know if this stops it
CAUTION : This fix is only valid for this specific machine, using it on another may break your computer
Open notepad and copy/paste the text in the quotebox below into it:
CreateRestorePoint: HKLM\SOFTWARE\Policies\Microsoft\Internet Explorer: Policy restriction <======= ATTENTION C:\ProgramData\SetStretch.exe C:\ProgramData\SetStretch.VBS EmptyTemp: CMD: bitsadmin /reset /allusers
Save this as fixlist.txt, in the same location as FRST.exe
https://dl.dropboxusercontent.com/u/73555776/FRSTfix.JPG
Run FRST and press Fix
On completion a log will be generated please post that
THEN
Please download AdwCleaner by Xplode onto your desktop.
[*]Close all open programs and internet browsers.
[*]Double click on AdwCleaner.exe to run the tool.
[*]Click on Scan.
[*]After the scan is complete click on “Clean”
[*]Confirm each time with Ok.
[*]Your computer will be rebooted automatically. A text file will open after the restart.
[*]Please post the content of that logfile with your next answer.
[*]You can find the logfile at C:\AdwCleaner[S1].txt as well.
I saved the file and ran fix, but there wasn’t a log generated, it restarted my computer. Did I do something wrong? Sorry, I’m super new to this…
Nope, there should be a fix log next to the FRST icon, is it there ?
Are you still getting alerts ?
Oh! I’m attaching it. I haven’t gotten an alert in awhile, should I still proceed with AdwCleaner?
Thanks so much for your help!
Yes proceed with AdwCleaner just to remove any remnants that I missed
Here’s that log:

: 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
https://dl.dropboxusercontent.com/u/73555776/javara.JPG
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
CryptoPrevent install this programme to lock down and prevent crypto ransome ware
