What is a Computer Virus? A computer virus is a program that can do a great deal of harm to a computer and its files. Each has a particular size and an identifying bit pattern. Antivirus software compares these characteristics of known viruses against each of the files (programs and data) on your computer. Once discovered, the infected file may be disinfected or deleted. It important to understand that a virus must execute on your computer before it can do any damage. Either you or one of your application programs must be tricked into executing it. The simple type of virus comes attached to an innocuous looking email. You may get an email from someone you met last year at a computer graphics convention, for example, with a subject line that says "My latest animation." You seem to remember meeting this person, so you willingly double-click on the attachment. Once it runs on your computer it can do anything you can do, like delete all your files, corrupting all your directory entries, or even sending an email to everyone in your address book with a copy of itself attached! Some virus programs come disguised as macros in word processing or spreadsheet documents, which are given control when the document is opened. More sophisticated virus programs exist that take advantage of a "bug" in one of your otherwise trustworthy application programs. A programmer notices that an application that many people have on their home computers reads data into a buffer, and that this application doesn't bother to check the size of the data it is reading in. The programmer sends you a data file that exceeds the size of that buffer, overriding some internal function in that application. When the application wants to execute that function, the programmer's code is executed instead, giving it an opportunity to do damage. Some computer virus programs are harmless, interrupting whatever you were doing to draw some silly image on your screen, for example. But it is best to employ good antivirus protection software, and always keep it and it's virus definitions up to date. There are other virus-like programs. One type lulls you into believing that you are getting a free program. You think this is some cool plotting program, for example, when it's really a program that lets the programmer take control of your computer through an Internet connection, captures your keystrokes to a file that gets sent to a remote location over the Internet, or just does a lot of damage, like a virus. Such a program is called a Trojan Horse, an allusion to how the Greeks captured Helen of Troy. Some propagate themselves by sending many copies of themselves over a network. These are called worms. But all of these names are just a semantic distinction: these programs are designed to do harm, even if it's only a minor interruption of your work, and the only up side seems to be an inflation of their designer's ego. Most common question we get is: How did I get this virus or spyware in the first place and how do I keep it from happening again? Most common source of virus infections are emails. A lot of spam emails will include a link to a website, which might even look legitimate, but deep down it has a malicious code included that will secretly install unwanted software on your PC. Virus removal can be surprisingly tricky. Pernicious and predatory, computer viruses seem to find the most creative and unscrupulous ways onto your pc. Even when you have your firewall, antivirus and malware protection correctly configured you are still likely to pick up viruses like barnacles on a ship along the way. When you need help with any kind of spyware removal you can always turn to ComLand Design specialists to get the job done. Best way to prevent infections it to never open email from people you don't know, and never click on links in messages if they look even a little suspicious. One wrong click could waste your entire day of productivity or fun. It's just not worth it. Another way of preventing a spyware or malware installation is to keep your system up to day with the latest software updates. This will include all Microsoft products like Windows XP, Windows Vista, Windows 7 & all Office application. Also make sure to frequently update software like Adobe Acrobat Reader, Adobe Flash, Shockwave or Java. Each day hackers and malicious code developers find flaws and vulnerabilities in the popular software packages for the purpose of exploiting them and installing a Trojan on your PC.Read full article on our website www.comland-design.com
How we recover data files? First, let's talk about what a data (or program) file really is. Your computer understands only binary code: a string of ones and zeros. Early computers grouped these patterns into 3-bit octal digits, making them easier to read and write. More modern computers group them into 4-bit groups of hex codes, and speak generally about 8-bit groups, called bytes. Memory, data files and messages are described as being kilobytes (kB), megabytes (MB), or sometimes even gigabytes (GB) in size. But it's all just strings on ones and zeros to your computer. A program or data file is a specific grouping of bytes, with a particular length, or size. When you save a file to your hard drive, the operating system (OS) finds an available group of sectors and writes the file as a set of 256-, 512-, or 1024-byte chunks, depending on the drive's sector size. The OS then writes the address of the sector where the file begins, its name, length, date, etc., into the drive's directory. When you open that file, the OS reads the directory, matches the file name, and gets each block of data from the beginning. When you delete a file, the directory entry is removed and the sectors that it occupied are marked free, but the data remains written on the disk. If you create a new file, however, there is a possibility that it will occupy some or all of those sectors, overwriting their contents. In that case, the file's data is lost forever. If you stop what you are doing, there is a possibility that the data may be recovered, but it must be done by a highly skilled engineers using very sophisticated softwares. We find what seems to be a complete data file in a stream of free sectors. A new file directory entry can be constructed that maps that stream of sectors, and the file is recovered. Always remember that the odds of recovery can be slim, and that taking precautions against a virus is by far the easiest pathway. ComLand Design provides complete hard drive recovery to recover data from inaccessible or damaged storage devices. Recovery can be done from all brands (like Western Digital, Seagate, Maxtor, Samsung, Toshiba etc.) and interfaces (such as IDE, EIDE, SATA, SCSI, SAS, FC, FireWire and USB etc.) of the hard drive.Disk drive data loss problem can be divided into two major categories which are described as follows:LOGICAL PROBLEM• Corrupted file system • Virus attack • Corrupted File Allocation Tables (FATS) • Corrupted Master File Tables • Formatted Disk DriveFile • System Damage • Loss of Password • Metadata Structure Damage, MBR (Master Boot Record) Corruption • Deleted File • Partition/Volume CorruptionPHYSICAL PROBLEMS• Clicking noise due to mechanical failure • Electrical failure • Misalignment of Read/Write Heads • Damaged Heads • Dropped or flooded drives • Bad Sectors on disk drives platters • Disk Drive not being recognized by bios etc. You can easily find out if your hard disk drive is experiencing any problem. A very common sign is an unusual sound such as grinding, clicking, scratching etc. This means either your disk drive is failed or is about to fail. You need to take special care at this point. Sometimes, the disk drive will give you some time to back up your data. Please take is seriously and back up your data as soon as possible. In some case, the Bios does not recognizes the disk drive. This is another example of physical damage to hard drive. Please do not keep trying rebooting you computer as this will further damage the hard disk drive. Disk data recovery is a very complex process, which requires experienced Disk Data Recovery Technicians and specially designed software tools to recover data. We at ComLand Design possess the both. Our highly experienced disk data recovery staff is equipped with state of the art software tools specially designed to work for disk data recovery. Please note: Not all data loss situations are recoverable and not all data recoveries are successful, regardless of the company or method used. Find more info on our web site www.comland-design.com
