Sam, did you install WINE?
I take it that you did, as it's the only way to get IE on a Linux OS.
You need to install some type of Windows AV within WINE, if that's possible. It's an Windows emulator, not a virtual machine, so I'd presume that one can install much anything that one can on Windows, with some limitations. Some has installed Office 2007/2010 via WINE.
That's why you need to secure the environment as well as possible, and use it just for what's needed. Actually you can check out Firefox & Google Chrome (has all plug-ins needed & kept up to date, Chromium requires setup of these) on your native Linux desktop. Here'e the link to Google Chrome for Linux, just download the 32 bit .deb version (top option, which matches yours). You'll have to provide your password to install & let the process finish, takes just a couple of minutes.
Afterwards, Google Chrome will be kept up to date along with the rest of your OS's software. See, you're saving time already, and as an added benefit, will always have the latest Flash & HTML5 plugins needed for Chrome, unfortunately, this isn't available for Firefox, Flash is several major versions behind & dozens of sub-versions.
To have two extra browsers that will be kept up to date, Opera's an option also, and uses the same Flash that Google Chrome does, nothing to configure.
Any concerns, just let us know.
