You can run some Windows apps in Ubuntu
Yes, though not out of the box, and not with guaranteed success. This is because software distributed in .exe are meant to run on Windows. These are not natively compatible with any other desktop operating system, including Mac OS X or Android.
Software installers made for Ubuntu (and other Linux distributions) tend to come as ‘.deb’ files. These can be installed similarly to .exe — you just double-click and follow any on-screen prompts.
But Linux is versatile. Using a compatibility layer called ‘Wine’ (which technically is not an emulator, but for simplicity’s sake can be referred to as one for shorthand) that can run many popular apps. They won’t work quite as well as they do on Windows, nor look as pretty. But, for many, it works well enough to use on a daily basis.
Notable Windows software that can run on Ubuntu through Wine includes older versions of Photoshop and early versions of Microsoft Office . For a list of compatible software [refer to the Wine App Database][1].
### Can Ubuntu Get Viruses? ###
It may have errors, but it doesn’t have viruses
Theoretically, yes. But in reality, no.
Linux distributions are built in a way that makes it incredibly hard for viruses, malware and root kits to be installed, much less run and do any significant damage.
For example, most applications run as a ‘regular user’ with no special administrative privileges, required for a virus to access critical parts of the operating system. Most software is also installed from well maintained and centralised sources, like the Ubuntu Software Center, and not random websites. This makes the risk of installing something that is infected negligible.
Should you use anti-virus on Ubuntu? That’s up to you. For peace of mind, or if you’re regularly using Windows software through Wine or dual-booting, you can install a free and open-source virus scanner app like ClamAV, available from the Software Center.
You can learn more about the potential for viruses on Linux/Ubuntu [on the Ubuntu Wiki][2].
### Can Ubuntu Play Games? ###
Steam has hundreds of high-quality games for Linux
Oh yes it can. From the traditionally simple distractions of 2D chess, word games and minesweeper to modern AAA titles requiring powerful graphics cards, Ubuntu has a diverse range of games available for it.
Your first port of call will be the **Ubuntu Software Center**. Here you’ll find a sizeable number of free, open-source and paid-for games, including acclaimed indie titles like World of Goo and Braid, as well as several sections filled with more traditional offerings, like PyChess, four-in-a-row and Scrabble clones.
For serious gaming you’ll want to grab **Steam for Linux**. This is where you’ll find some of the latest and greatest games available, spanning the full gamut of genres.
Also keep an eye on the [Humble Bundle][3]. These ‘pay what you want’ packages are held for two weeks every month or so. The folks at Humble have been fantastic supporters of Linux as a gaming platform, single-handily ensuring the Linux debut of many touted titles.
