I regularly use the website Mediafire.com for sending and downloading files, but in the last week or so its download pages have been occasionally triggering “HTTP Malicious Toolkit Variant Activity 2” detections, with Mediafire’s IP listed as the attacker. This doesn’t happen every time, and I can usually reload the page and continue as usual. All of my scans afterward have come up clean. Is there anything to worry about here, or could this just be a false positive?
