Computers are mostly being affected via the spread of infected e-mails which carry the hacked WMF file as an attachment
I email back and forth with my girlfriend, and that's it. And since I have gmail, I don't get any spam o_o;
* Viewing a malicious website in Internet Explorer (in which case the file may be automatically downloaded and opened)
*uses Firefox*
* Viewing such a website in any other web browser and agreeing to open and download at the prompt
*rarely downloads anything*
* Previewing an infected file in Windows Explorer
*doesn't use Internet Exploder*
* Previewing infected emails in older versions of Microsoft Outlook
I've never used Outlook once XD
* Indexing a hard disk containing an infected file with Google Desktop.
Don't have it o_O
So my complete lack of internet activity outside of PC saves me again XD
