On my home machine yesterday just happened to notice on C drive 2 strange folders. they reappear even though you delete them.

norton/malwarebytes paid and cyberfree ransomeware are on the machine

tdsskiller shows nothing.

the ransomware program I have keeps saying something is found and it is stopping it. but then the files come back. here's an example in the attachments

kaspersky security scan i just downloaded says
Displaying drives in Windows Explorer is limitedDisk absence in Windows Explorer seriously hampers the ability of the user to work with their applications and data. This problem is usually due to active malware. Failure to correct the problem does not allow the running of applications or opening of files with data that the user needs for work.

Autorun from network drives is enabledThere are types of malware that reproduce by copying network drives using the autorun.inf file. This allows an attacker to gain control over the system and user data

aside from all this the machine runs perfectly. just when i delete the 2 folders in C they come back right away . and then the ransomeware program gets triggered and says another process may be trying to conceal its activity by abusing explorer.exe

the company wrote back. sure would be nice if this was in the FAQ!!!!!

The drive and folders that you're seeing are expected behavior of RansomFree. They are bait files (like honeypots if you're familiar with this technology) that lure ransomware toward them first. This enables RansomFree to detect and stop ransomware before it's able to encrypt your valuable files. These are designed to be hidden so if you wish, you can enable hidden files and folders in your system settings and they won't clutter your directory. Let us know if you have any other questions.

what do you mean? i have paid norton but since it showed clear i downloaded the kaspersky quick scan or whatever its called since i know nothing is perfect.

also i have paid malwarebytes and that has continually showed 'pup no drives' for a while but it appears every time i reboot. and malwarebytes cleans it every time.

they hog system resources make your machine run terrible I would expect leave malwarebytes paid and cyberfree ransomeware and download the removal tools for norton/ and kaspersky they will not properly uninstall without them

actually i may have found the answer but never heard of a honeypot. i believe the program creates directories and is a trigger if you get ransomeware. i guess i can turn off the program and try to delete the files and see what happens.

The folders the product creates will be randomly named and usually at the top of the C drive. They are the Honeypots- too bad some ransomware do not have a sweet tooth.

Some antivirus solutions would create fake/honey pot folders to help with ransomware issue. If ransomware encrypts and files in the folder antivirus/anti-malware solutions can react faster. Cyberfree was known to do just that.
