Linux system… well isn’t this cool – Screenshot

33 tabs open in Firefox and it is still using only 147Mb of RAM. Seems pretty cool to me compared to previous Memory footpath of Firefox. Another thing is that I have Apache, Perl, Python, DHCP3, VLC and all those stuff open along with whole lot of folders but the system RAM usage is only 396Mb. The system doesn’t seem to be anywhere near slowing down. See the Screenshot of System Monitor (One of my systems run Linux)

Well for heavens sake I can’t actually imagine this on a windows machine with a similar config. (My Linux system is clocked by Semptron LE1200 – cheap but more than enough for me)

Windows virus infects Linux

Windows has always been considered a vulnerable OS to viruses, but not Linux. I haven’t heared about any virus for Linux except for some university project somewhere. So do not expect me to discover a new virus for Linux. This is much more interesting, actually.

The virus I found, running, on Linux (Ubuntu to be specific) was actually a Windows virus. Some of you might already have figured out the culprit here. So how did the Windows virus manage to run on Linux which doesn’t even support any Windows specific file.

Wine is a software application which allows Unix like OSes to run programs written for Windows. So if you set the default assocaiation for exe files to Wine in Linux, you can just double click on exe files and run them just like you do in Windows. So if this is right then you can get infected with almost any Windows Virus in Linux.. although the consequences may not be much important.

Any Virus using AutoPlay can infect by this method. So if the virus is running after you inserted a USB drive it will copy itself to any external storage device automatically. So virtually you get your USB drive infected with virus from a LINUX system. To prevent this from happeneing do not set the default association for exe file to Wine. Just leave it in the Open with list and chose it when you need to run an exe file.
