New worm infecting computers at an alarming rate

Sunday, February 8th, 2009

The recent studies have found out that a new computer virus has infected nearly 20 million computers throughout the world and is also spreading really fast. This virus or worm is known by several names where down ad up, Downandup and conficker are some of the commonly known names and this worm is very deceiving. It has been found that a window would given a pop up warning that states that your computer has in infection and show up an anti virus software. However when you try to purchase the anti virus software in order to delete the virus it would actually steal all you credit card and other important information while even infect your computer.

Some of the experts find that is can be one of the worst infection to infect computers in the last six years and it is also easy to fall for it. Robert Nash the computer technician said that the virus looks legit and unless computer users are informed about this or know about the virus would easily make its way into the computers. However according to Joe Kadar the computer technician the virus attach has gone from around 2.4 million machines to nearly 8.9 million machines infected within one day which also makes it one of the fastest spreading virus in the world.

This virus mainly spreads by infiltrating in tot eh flash drives. So, when the virus has made its way into the flash driver and has infected the computer machine you are using, it can even infect all the computers in the network. The radio personality for instance would basically rely on their computer for song requests and to update their websites. Here if the computer develops the virus it would make the workday much more difficult, while your computer might also transmit the virus into other computers connected to the machine.

Therefore following the same patter of predictions that has let to the devastating worm attach, has actually let security analysts to start focusing on the new crop of Microsoft. The windows vulnerabilities along with the attack tools to that are created to take advantage of them can all together create a potential new family of computer virus. Just after a short period Microsoft had warned their users about the new vulnerabilities in remote procedure call protocol of windows, the same software which opened nearly a million machines to the virus attach is actually the code that is being circulated through the web. This means that it is important you stay safe as this virus can actually cause a lot of problems.

Most of the security intelligence companies and even computer security companies recommend that you update your anti virus program so that you eventually kill out the worm from your computer. Although purchasing new anti virus can prove to be beneficial it would rather be hard to trust its reliability to be free from malware. Therefore you can just keep updating your anti virus frequently from the official dealer in order to eventually remove the entire worm and stay way from it.

New Windows virius variants cause increased infections

Friday, January 30th, 2009

According to the study conducted by Microsoft, there has been a worm virus which is infecting computers since the month of October has now spread to nearly eight million computers throughout the world which has also created fears which this infection would reach huge new levels by the year 2009. this virus worm is called as Kido, Downadup and Conficker can actually be transferred through different ways that include through the commonly used flash drivers which makes it difficult to protect against it even though your computer system is efficient with current updates. However this does not mean that nothing can be done stay away from this virus as you can use a reliable anti virus software and also secure all your passwords which would be hard for any of such programs to break through.

Graham Cluley who is a senior technology consultant of the computer security company named Sophos said that Microsoft has done a great job by updating the home computers of people by it is found that virus still continues to infect business who did not bother to use the patch update. He also said that the shortage of IT staff during the holiday bread did not help much while also the rolling out of the patch update over a large number of users and companies was very touch. He again added that if any of the business computer users use week passwords like QWERTY or 12345 then this virus attach can easily crack them within a short time. This harmful virus mainly works by making its way through the ‘services.exe’ files that are the most important for windows functions and after merging with it the virus lets itself to cover-up as a driver while also copying itself until the virus has modified your computer registry.

After this is done the virus would create a particular server that lets different malware from the website of a hacker to be automatically downloaded to your computer system which would reset all the restore points to make is almost impossible to regain complete control over your machine. As this virus also generated thousands of rotating websites it also makes it impossible to track the original site files and it would bury it in different URLs any of which can be one of the hacker. Although Microsoft is working hard to identity and combat this new virus, some new versions of malware make it difficult.

Eddy willems who is the security expert at Kaspersky Lab said to the reporters that there is a new variant released just less than a week before and it is the one that is causing the most problems. He added that replication methods can be good way, but as it used different mechanisms like USB sticks, if anyone uses an infected USB to another company then it would infect the entire network of the company. The virus can also download a lot of content that can create new variants through the mechanism. Therefore the initial solutions by Microsoft can be best ways to stay away from this virus to keep your and your company’s machines working efficiently.

New virus may have infected 1 in 3 Windows systems

Wednesday, January 28th, 2009

There had been a study conducted by the Panda Security regarding a new virus attacking the PCs as they came to a conclusion that the computer virus could infect one computer from every three computers in the world. The worm or virus called Conficker or Downadup had been first found out about during the last October, but there are also more powerful versions of the same that are aggressively attacking computer systems for a little more than a week. This virus is found to spread through the most commonly used memory sticks and even through unsecure computer networks and through computers that have not been updated with the latest security updates.

Additionally, Microsoft has also studied about this unique computer virus and has found that this virus mainly works by pushing itself into the codes of most windows executable files that are called as ‘Services.exe’. the virus then copies itself in the windows operating system folder where it becomes capable of creating HTTP server. After this HTTP server is created the virus also starts to download files from the website of a hacker.

However according to the Panda Security company that monitors, according to their test on virus attack have said that from all the windows operating systems that they had scanned, they found that every 1 in total of 16 computers had been infected by this virus. However it was also found that only two million machines had been scanned for this virus and this led panda to come out with an estimate that the number of computer systems to be infected would be as high as every one among three computers according to the compute world.

The even more awful thing about this virus is that it has already caused a lot of havoc in England. Additionally according to the multiple reports the virus had also broken out most of the computer systems and the e-mail services within the ministry of Defense. Some of the experts of the governments from all over the world also believe that the complexity of this virus and also the growing number of mutations has lead them to believe that even the worst type from this virus is actually yet to come.  Therefore for its own part, Microsoft Corporation has recently issued a security bulletin along with a patch for this quickly spreading dangerous virus. This download of Patch from Microsoft is easily available from the windows update tool that is located in the start menu of Microsoft windows computer systems. Apart from this the security experts also give advise that you should make sure that you have a good password and not something like QWERTY or 123456 and also some other type of anti virus software to be installed in your machine. However as this dangerous virus changes it is actually the key in keeping your computer system updated as soon as the patch is available for you. These steps can help you can stay away or and avoid the virus entering your computer.

Avoiding identity theft

Monday, January 12th, 2009

If someone dares succeeds in stealing your ‘online identity’, they get enabled to pretend that they are representing you with regards to online activities within the region of so-called ‘Social Networking’. ‘Social Network’ can be referred to as a people’s association that is drawn together through work, hobby, or family. This term was invented in 50s by Prof. J.A. Barnes, who went on to define a social network’s size as a constellation of around 100-150 people. However, after the invention of www, i.e. World Wide Web, the sites dealing with social networking have come through online, thereby providing networks consisting of thousands of members.The present scenario is such that these sites are termed as virtual communities comprising of people who show sheer interest in a specified subject. At times, they also serve the purpose of being a place for hanging out together. On such sites, associates create an online profile of their own with pictures, biographical data, dislikes, likes, and the other information chosen by them to post. The communication gets carried on amongst themselves through voice, instant message, chat, blogs, or video conference. In situations like these, it’s not difficult for someone to steal your identity. It is sad that identity hijackers hardly get caught and continue perpetrating their crimes time and again. These thieves are so smart that they make sure to not leave any clue in this regard.
You can avoid identity theft by just one means: extreme caution. You need to keep your login details a secret. Make it a point to not let even the single detail leak. The most near and dear one should also not be trusted in this regard.

Make a point to not use the same machine frequently. Keep on switching from one PC or one ATM to the other. Thieves are clever enough to harvest off the machine while you use your ATM card. So, avoid frequent use of one machine. In this age of ‘connections’, a blunt truth is that your personal information can get stored in the hard dish of your PC, thereby waiting for the hijacker to lay his/her hands (on it). Furthermore, you do not require any of fancy technologies for digging it out. Till you already go on practising something called ‘safe computing’, it can be found by following certain simple steps mentioned below: Search for a form available online. You can make use of ‘Contact centre’ form for any of the purposes of your liking. However, any form wherein information would be filled by you would do. It’s advisable to not harvest any of the personal information from the form. However, if you happen to fill this form by making use of Firefox, Internet Explorer, or the other browser, make known that you have been compromised if you enter personal information like name, bank account number, phone number, IRD, etc. as it can be easily harvested by the identity thief.
