From the drop-down menu select 'Choose default program', then click 'Browse' and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the HTM file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?Many files contain only simple text data. It is possible that while opening unknown files (e.g. HTM) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
When it comes to spam messages, conventional wisdom dictates that you shouldn't follow links or call phone numbers in the message, order products from the spammer, or open files attached to the email. We all should know by now that you should never open attached executable files, and spam filters now treat all .exe files as suspicious. When spammers began flooding inboxes with .zip files containing executables, we caught on pretty quickly as well.
But HTML isn't executable — it's just plain text — so does that mean it's safe to open attachments when they're just HTML files? Hell no! Case in point: this doozy that came through our spam bucket last week.

Yeah, genius, we figured out your awesome trick. It's the 'insert a random letter between every character' encryption algorithm, first invented in the year one by a five year old girl who wanted to pass a clay tablet to her friend in class without the teacher being able to read her Aramaic. The only significant difference is that there are no little hearts drawn over the 'i's. RSA and Bruce Schneier, eat your hearts out. These guys are obviously l33t.

In the end, the page directs a vulnerable browser to download the backdoor to the victim's computer. The backdoor pulls down Zbot. Zbot contacts its command and control server, pulls down a data file with instructions, and makes another copy of itself on the infected computer's hard drive.
In addition, the backdoor changes all the Security Zone settings in IE, clears your cookies, changes the settings for the Windows firewall to permit Windows Explorer (not IE) to receive data from anyone on the Internet, and makes other modifications to security settings that make it far more likely a victim will further infect him- or herself.

Bottom line, it doesn't matter what kind of attachment you get. Don't open anything attached to a spam email in a browser. After all, it's pretty obvious that this is just a ruse. Jimmy Fallon doesn't need your money, just some decent Nielsen numbers in his time slot, and that's one thing Zbot can't steal.
