  • How to know if your computer is hit by a dnschanger virus?

    - by kira
    The Federal Bureau of Investigation (FBI) is on the final stage of its Operation Ghost Click, which strikes against the menace of the DNSChanger virus and trojan. Infected PCs running the DNSChanger malware at unawares are in the danger of going offline on this coming Monday (July 9) when the FBI plans to pull down the online servers that communicate with the virus on host computers. After gaining access to a host PC, the DNSChanger virus tries to modify the DNS (Domain Name Server) settings, which are essential for Internet access, to send traffic to malicious servers. These poisoned web addresses in turn point traffic generated through infected PCs to fake or unsafe websites, most of them running online scams. There are also reports that the DNSChanger virus also acts as a trojan, allowing perpetrators of the hack attack to gain access to infected PCs. Google issued a general advisory for netizens in May earlier this year to detect and remove DNSChanger from infected PCs. According to our report, some 5 lakh PCs were still infected by the DNSChanger virus in May 2012. The first report of the DNSChanger virus and its affiliation with an international group of hackers first came to light towards the end of last year, and the FBI has been chasing them down ever since. The group behind the DNSChanger virus is estimated to have infected close to 4 million PCs around the world in 2011, until the FBI shut them down in November. In the last stage of Operation Ghost Click, the FBI plans to pull the plug and bring down the temporary rogue DNS servers on Monday, July 9, according to an official announcement. As a result, PCs still infected by the DNSChanger virus will be unable to access the Internet. How do you know if your PC has the DNSChanger virus? Don’t worry. Google has explained the hack attack and tools to remove the malware on its official blog. Trend Micro also has extensive step-by-step instructions to check if your Windows PC or Mac is infected by the virus. The article is found at http://www.thinkdigit.com/Internet/Google-warns-users-about-DNSChanger-malware_9665.html How to check if my computer is one of those affected?

  • Chrome pop-up blocker fail?

    - by Count Zero
    I have this problem since just a few days. I've been a heavy Chrome user for several years, but it never happened before: Sometimes absolutely uncalled for pop-ups appear, when I click something absolutely legit. It seems to happen at a very precise rate of two pop-ups every hour or so. The pop-ups are not very varied, it seems to be a fixed set of some 4-5 ads. At first I thought I caught some malware, but after a full scan with Malwarebytes Anti-Malware, I found absolutely nothing. In addition the problem exists only with Chrome. When I use Firefox, this never ever happens. What is even more puzzling is that it happens on both of my rigs and started on the same day. I have a removable storage that I dock to both of them and access one machine from the other via RDP, but still... It seems this is a problem that others face too. See this Google forum and here. Could it be that the latest Chrome build is just acting up? (Just in case it matters: I run Chrome version 24.0.1312.57 m on Win 7.)

  • McAfee Virus Scan and Oracle RAC

    - by Lee Gathercole
    Hi, We're experiencing a strange problem with Oracle RAC and McAfee anti-virus. As part of the installation of the Oracle RAC we disable anti virus as directed. We have had our RAC running fine, but when we came to re-enable the AV and reboot we got the BSOD. Abnormal Program Termination (BugCheck, STOP: 0x00000035 (0x8E984678, 0x00000000, 0x00000000, 0x00000000 NO_MORE_IRP_STACK_LOCATIONS Following the standard process of raising this problem with Microsoft they identify the problem and also a fix. Microsoft talk about too many file filter drivers being present and pushing the DFS upper limit beyond the default size. Upping this value, as per msdn, has no impact. We're able to recover from this BSOD by disabling AV. We don't have the problem if we run the AV service manually whilst the system is up. However, if we make the service automatic we fail to boot. Tech Details 2 Node Oracle 10g Cluster 2 * Windows 2003 SP2, 16GB RAM, Quad Core 3ghz Processor SAN attached storage McAfee VirusScan Enterprise 8.5.0i, Scan Engine (5300.2777), DAT Version (5536.0000) Thanks Lee

  • Windows and system processes

    - by jemper
    Note: I've asked this question in a similiar format on superuser but it seems like it may fit here on SO better. It definitely also is about programming as it concerns parts of the Win32 API, Windows in general and process management. So there are these processes that can't be terminated with taskkill - system processes in general. But there also is, for example my Anti Virus program that makes itself "unterminateable". How can I access and mainly terminate system processes under windows? (kill.exe by Microsoft doesn't work) How do processes like anti-virus programs protect themselves? How can you turn them off again, then?

  • Virus in Subversion repository, what to do?

    - by furtelwart
    Imagine the following situation: A virus infected file was commited into a Subversion repository. A Anti Virus scanner runs on the server and also scans the Subversion repository. The Anti Virus scanner will delete the affected revision or move it to quarantine. The consequence is a broken repository. If the revision file is recoverable (from quarantine), how to solve this problem? I have some goals to achieve: The AV is not allowed to be disabled or excluded from the directories. The virus infected file must not be stored in the repository The repository must be consistens and usable. What is the nicest solution for this little problem?

  • How do I fix Google Earth 6.2.2 theme and fonts in 12.04?

    - by Joshua Robison
    Here is the problem. I would like to know how to get Google Earth using better fonts with anti-aliasing for English and Japanese. Don't know what these fonts are but they are hideous and completely different from my system fonts or Libre Office fonts or even QT apps like VLC and MiniTube. I'm using 12.04 LTS 32bit and almost had complete success with the 11.10 fix posted here Google Earth and Skype theme the theme and fonts will show up correctly for about 5 seconds before the program crashes.

  • Premature-Optimization and Performance Anxiety

    - by James Michael Hare
    While writing my post analyzing the new .NET 4 ConcurrentDictionary class (here), I fell into one of the classic blunders that I myself always love to warn about.  After analyzing the differences of time between a Dictionary with locking versus the new ConcurrentDictionary class, I noted that the ConcurrentDictionary was faster with read-heavy multi-threaded operations.  Then, I made the classic blunder of thinking that because the original Dictionary with locking was faster for those write-heavy uses, it was the best choice for those types of tasks.  In short, I fell into the premature-optimization anti-pattern. Basically, the premature-optimization anti-pattern is when a developer is coding very early for a perceived (whether rightly-or-wrongly) performance gain and sacrificing good design and maintainability in the process.  At best, the performance gains are usually negligible and at worst, can either negatively impact performance, or can degrade maintainability so much that time to market suffers or the code becomes very fragile due to the complexity. Keep in mind the distinction above.  I'm not talking about valid performance decisions.  There are decisions one should make when designing and writing an application that are valid performance decisions.  Examples of this are knowing the best data structures for a given situation (Dictionary versus List, for example) and choosing performance algorithms (linear search vs. binary search).  But these in my mind are macro optimizations.  The error is not in deciding to use a better data structure or algorithm, the anti-pattern as stated above is when you attempt to over-optimize early on in such a way that it sacrifices maintainability. In my case, I was actually considering trading the safety and maintainability gains of the ConcurrentDictionary (no locking required) for a slight performance gain by using the Dictionary with locking.  This would have been a mistake as I would be trading maintainability (ConcurrentDictionary requires no locking which helps readability) and safety (ConcurrentDictionary is safe for iteration even while being modified and you don't risk the developer locking incorrectly) -- and I fell for it even when I knew to watch out for it.  I think in my case, and it may be true for others as well, a large part of it was due to the time I was trained as a developer.  I began college in in the 90s when C and C++ was king and hardware speed and memory were still relatively priceless commodities and not to be squandered.  In those days, using a long instead of a short could waste precious resources, and as such, we were taught to try to minimize space and favor performance.  This is why in many cases such early code-bases were very hard to maintain.  I don't know how many times I heard back then to avoid too many function calls because of the overhead -- and in fact just last year I heard a new hire in the company where I work declare that she didn't want to refactor a long method because of function call overhead.  Now back then, that may have been a valid concern, but with today's modern hardware even if you're calling a trivial method in an extremely tight loop (which chances are the JIT compiler would optimize anyway) the results of removing method calls to speed up performance are negligible for the great majority of applications.  Now, obviously, there are those coding applications where speed is absolutely king (for example drivers, computer games, operating systems) where such sacrifices may be made.  But I would strongly advice against such optimization because of it's cost.  Many folks that are performing an optimization think it's always a win-win.  That they're simply adding speed to the application, what could possibly be wrong with that?  What they don't realize is the cost of their choice.  For every piece of straight-forward code that you obfuscate with performance enhancements, you risk the introduction of bugs in the long term technical debt of the application.  It will become so fragile over time that maintenance will become a nightmare.  I've seen such applications in places I have worked.  There are times I've seen applications where the designer was so obsessed with performance that they even designed their own memory management system for their application to try to squeeze out every ounce of performance.  Unfortunately, the application stability often suffers as a result and it is very difficult for anyone other than the original designer to maintain. I've even seen this recently where I heard a C++ developer bemoaning that in VS2010 the iterators are about twice as slow as they used to be because Microsoft added range checking (probably as part of the 0x standard implementation).  To me this was almost a joke.  Twice as slow sounds bad, but it almost never as bad as you think -- especially if you're gaining safety.  The only time twice is really that much slower is when once was too slow to begin with.  Think about it.  2 minutes is slow as a response time because 1 minute is slow.  But if an iterator takes 1 microsecond to move one position and a new, safer iterator takes 2 microseconds, this is trivial!  The only way you'd ever really notice this would be in iterating a collection just for the sake of iterating (i.e. no other operations).  To my mind, the added safety makes the extra time worth it. Always favor safety and maintainability when you can.  I know it can be a hard habit to break, especially if you started out your career early or in a language such as C where they are very performance conscious.  But in reality, these type of micro-optimizations only end up hurting you in the long run. Remember the two laws of optimization.  I'm not sure where I first heard these, but they are so true: For beginners: Do not optimize. For experts: Do not optimize yet. This is so true.  If you're a beginner, resist the urge to optimize at all costs.  And if you are an expert, delay that decision.  As long as you have chosen the right data structures and algorithms for your task, your performance will probably be more than sufficient.  Chances are it will be network, database, or disk hits that will be your slow-down, not your code.  As they say, 98% of your code's bottleneck is in 2% of your code so premature-optimization may add maintenance and safety debt that won't have any measurable impact.  Instead, code for maintainability and safety, and then, and only then, when you find a true bottleneck, then you should go back and optimize further.

  • Get to Know a Candidate (2 of 25): Merlin Miller&ndash;American Third Position Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Meet Merlin Miller of American Third Position Party In addition to being American Third Position Party nominee, Miller is an independent film maker.  He is a graduate of West Point and has commanded two units in the United States Army.  After military service he worked as an industrial engineering manager for Michelin Tire.  He learned about film making by earning an MFA from the University of Southern California. Mr. Miller is on the ballot in: CO, NJ, and TN. In the 2000’s, Miller began taking an increasingly paleoconservative political stance.  He claimed that Hollywood “ surreptitiously seeks to destroy our European-American heritage and our Christian-based traditional values, and replace them with values that debase these traditional values and elevate minorities as paragons of virtue and wisdom....Today’s motion pictures, in concert with other forms of mass media entertainment, are the greatest enemies to the well-being of our progeny and the future of our country.” Miller states that he "doesn't like" interracial marriage; however, he does not support outlawing interracial marriage, either.  Miller has denied being anti-Semitic, instead claiming that he merely opposes "favoritism" granted to Jews in the film industry.  He also opposes illegal immigration and what he refers to as "wide open borders" in the United States. The American Third Position Party (A3P) is a third positionist American political party which promotes white supremacy.  It was officially launched in January 2010 (although in November 2009 it filed papers to get on a ballot in California) partially to channel the right-wing populist resentment engendered by the financial crisis of 2007–2010 and the policies of the Obama administration and defines its principal mission as representing the political interests of white Americans. The party takes a strong stand against immigration and globalization, and strongly supports an anti-interventionist foreign policy. Although the party does not support labor unions, they do strongly support the labor rights of the American working class on a platform of placing American workers first over illegal immigrant workers and banning of overseas corporate relocation of American industry and technology Third Position or Third Alternative refers to a revolutionary nationalist political position that emphasizes its opposition to both communism and capitalism. Advocates of Third Position politics typically present themselves as "beyond left and right", instead claiming to syncretize radical ideas from both ends of the political spectrum Learn more about Merlin Miller and American Third Position Party on Wikipedia.

  • Calculating the 2D edge normals of a triangle

    What's a reliable way to calculate a 2D normal vector for each edge of a triangle, so that each normal is pointing outwards from the triangle? To clarify, given any triangle - for each edge (e.g p2-p1), I need to calculate a 2D normal vector pointing away from the triangle at right angles to the edge (for simplicity we can assume that the points are being specified in an anti-clockwise direction). I've coded a couple of hacky attempts, but I'm sure I'm overlooking some simple method and Google isn't being that helpful today - that and I haven't had my daily caffeine yet!
