  • Architecture diagram of a computer virus

    - by Shiraz Bhaiji
    I am looking for an architecture diagram of a computer virus. Does anyone have a link to a good example? Edit Looks like I am getting hammered with downvotes. I agree that there is no single architecture for a virus. But somethings must be included for a program to be a virus. Example for components in the SAD: Replication method Trigger Payload Hosts targeted Vulnerabilities targeted Anti detection method

  • My computer has begun to restart after I upgraded

    - by Voidcode
    After updating to Ubuntu 11.04. My computer started to turn off and reboot. This happens about every half hour, I think there is a tendency to happen when I work with multiple applications at once. It is both my Desktop and Labtop. I has installed- BOINE Manager, PlayOnLinix GIMP, Qt, Wine, VLC-player, Blender 2.57 Otherwise is all as default. Update: See my /var/log/kern.log.1 here: http://paste.ubuntu.com/608690

  • Migrate Rhythbox from one computer to another with different username

    - by deshmukh
    I want to migrate Rhythmbox from one computer to another. I have different usernames in both the computers. I will need to carry music files, covers, playcounts, ratings, playlists, etc. Merely copying music files and .local/share/rhythmbox does not work (I guess because Music locations are different on both the computers). What is the best way to achieve this? I will at least like to carry ratings and playlists.

  • The Benefits of Computer Games

  • Computer Engineer in CS Interview

    - by blasteye
    As a Computer Engineering student, while in school I've primarily dealt with C, Matlab, and VHDL. On my own though, i learned a bit about OOP (Polymorphism, inheritance, encapsulation), and have done quite a bit of web development using JavaScript/PHP/Node.js While at coding interviews I've be asked academia CS questions such as "abstract vs interface". The problem is that I didn't know the official terminology, but I have dealt with this type of programming decisions/concepts. Could anyone recommend a good resource for me to learn these academia CS terms?

  • Computer is running slow with Ubuntu

    - by Bart
    Why my computer runs too slow when I install Ubuntu or any other Linux (Debian works better than other distros), but with windows works fine...? My configuration is: Processor: Intel Celeron CPU 1.70GHz Graphics: Ati Radeon 9250 128 MB HD: Western Digital 120GB RAM: 2GB DDR1 Motherboard: MSI (MS-6566) Is there anything unsuported by Ubuntu, or any Linux. If so, is there any way to get it work fine (visual effects are not important to me). What do I need to do?

  • Reduce power consumption of gaming computer while idle

    - by White Phoenix
    This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 clocked @ 3.3 Ghz 3x DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 oc'd at 800/1600/1850 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) I've already seen this post Reduce power use on computer and this post How do I lower power consumption of my computer and while useful, I'm looking for answers specific to my build and OS. I'm pretty sure this build is a energy-intensive build by default, but I want to try to reduce the amount of energy my build uses when I leave it idle (when I go to bed or go out, etc). The first requirement for this machine is that I need to leave it on, so I cannot turn it off while it's being unused. I run it as a file server for personal reasons and I also leave it on in case people leave me messages on various IM services and chat clients (IRC, MSN, Steam, XFire, Pidgin, etc). I'm also unable to replace the parts in my computer with a cheaper "greener" part. What are some ways to minimize the amount of power the machine uses? I'm already using a high efficiency power supply (80 Plus Gold), but I imagine there's other things that can be done in the BIOS and Windows' power settings to reduce power usage while I'm not using the computer. From what I can tell, I can't use Sleep since that'll disable network access (whole reason why I leave the computer on in the first place). I already turn off my monitor when it's not in use. I enabled Intel SpeedStep within the BIOS (I know, I have a 965 and why am I enabling SpeedStep?) Should I bring the graphics card back to stock speeds and lower the clock on the processor even more? Main reason why I'm asking is I think this computer alone is the reason why my power bill is high, so I want to reduce its consumption to as low as possible without having to shut the thing down.

  • How can visiting a webpage infect your computer?

    - by Cybis
    My mother's computer recently became infected with some sort of rootkit. It began when she received an email from a close friend asking her to check out some sort of webpage. I never saw it, but my mother said it was just a blog of some sort, nothing interesting. A few days later, my mother signed in on the PayPal homepage. PayPal gave some sort of security notice which stated that to prevent fraud, they needed some additional personal information. Among some of the more normal information (name, address, etc.), they asked for her SSN and bank PIN! She refused to submit that information and complained to PayPal that they shouldn't ask for it. PayPal said they would never ask for such information and that it wasn't their webpage. There was no such "security notice" when she logged in from a different computer, only from hers. It wasn't a phishing attempt or redirection of some sort, IE clearly showed an SSL connection to https://www.paypal.com/ She remembered that strange email and asked her friend about it - the friend never sent it! Obviously, something on her computer was intercepting the PayPal homepage and that email was the only other strange thing to happen recently. She entrusted me to fix everything. I nuked the computer from orbit since it was the only way to be sure (i.e., reformatted her hard drive and did a clean install). That seemed to work fine. But that got me wondering... my mother didn't download and run anything. There were no weird ActiveX controls running (she's not computer illiterate and knows not to install them), and she only uses webmail (i.e., no Outlook vulnerability). When I think webpages, I think content presentation - JavaScript, HTML, and maybe some Flash. How could that possibly install and execute arbitrary software on your computer? It seems kinda weird/stupid that such vulnerabilities exist.
