Virus Disguised as IE 7 Download Beware of an email from admin [at] Microsoft[dot] com that contains a blue Microsoft style image that that has an link to download IE7.exe from an unknown web server. The virus edits the registry files to ensure it is installed, and it will try to download additional files from the internet. Microsoft recommends IE (v7 and below) users to use an rival internet browser (Firefox, Chrome, etc) temporarily or increase there security settings to the highest (which will decrease the speed of your browsing). Microsoft is currently investigating this issue and working on an patch for IE users. More Info at http://www.pcworld.com/article/130267/virus_disguised_as_ie_7_download.html
