: Website flagged by antivirus software I operate a file hosting site, and recently I've found that some antivirus software have flagged it as malicious due to a few nasty files people have uploaded.

@Holmes151

What I would suggest you do is Google around, see what sites are reporting yours as malicious. For example, I found that this post on Free PC Security is where most of the reports come from. Try contacting that site and asking them why your whole domain is flagged, and request that they remove you from their list.

Also you could check out websites like Web of Trust or SiteAdvisor (links go directly to the report on AnyHub) to see why your site is flagged and if you can rectify this situation. Most of these sites give you help on how to get your reputation up and some even let you post a comment as a site owner explaining what happened.

I've also implemented a VirusTotal check on upload of any .exe, .dll or .com files.


And what if I rename my virus.exe to cutekittens.jpg? You need to scan every file regardless of filename.

But once you have that in place I would suggest that you are pretty safe. Obviously the core problem is hosting malicious files. Anti-Virus applications are well within their right to block the entire site if a user is able to download a virus.

If, by your own admission, your users are uploading nasty files, then the anti-virus programs are doing their job and are will within their rights to block your site from their users computers, and I don't know if there's any way really around this.

The first question I would ask is what is your site hosting? And is ESET flagging just that file or your entire site?

And then I would say not to worry about it really. Unless Google blacklists your site, your in the clear. That said, if a desktop AV flags your site as malicious, how long until/if Google does?
