I think that the major part of us are using Winzip as the favourite compression tool. If yes, now it's the time for a "forced" software upgrade.
There's a new security alert by Secunia (my favourite source for security flaws) that says that Winzip (all versions from 3.X to 9) has unspecified Multiple Buffer Overflow Vulnerabilities. 
In details there problems are:
1) Some unspecified vulnerabilities which can be exploited to cause buffer overflows. Successful exploitation can potentially lead to execution of arbitrary code.
2) A problem caused due to insufficient validation of command-line arguments. This can be exploited by using a specially crafted argument to cause a buffer overflow and potentially execute arbitrary code.
Solution to this? An upgrade to 9.0 SR-1 version HERE.
Something interesting downloads to check:
- Internet Information Services 6.0 Migration Tool: a command line tool that automates several of the steps needed to move a Web application from IIS 4.0, IIS 5.0 or IIS 6.0 to a clean installation of Internet Information Services (IIS) 6.0. The tool transfers configuration data, Web site content, and application settings to a new IIS 6.0 server.
- Windows Media Player 9 Series and 10 Series Add-in for Microsoft FrontPage: an add-in that enables new capabilities for FrontPage users, such as: Easily embed the Windows Media Player 9 Series or 10 Series control into FrontPage web pages and SharePoint sites; Control the look and feel of the media playback experience; Easily convert your media files for efficient network delivery; Publish to a Web or streaming server automatically.
- Remote Desktop Web Connection XPSP2 [6,0,2600,0]: this ActiveX control provides most of the same functionality as the full Remote Desktop Connection software; however, the Remote Desktop Web Connection is designed to deliver this functionality over the Web. The Web package Setup program installs the downloadable ActiveX control and sample Web page on a server running Internet Information Services (IIS) 4.0 or later.
