Step4 - If this file got deleted immediately...then it means that your antivirus is working properly and updated !!

Step5 - If this doesnt happens and you see the saved file in that folder do right click the file and select scan with your installed antivirus and if the scan shows the file then it means your antivirus is working properly but not updated with a new version, as best antivirus softwares detect any virus (at the same second when you save the same in your system)without your effort of going to specified folder and scanning the folder.

Step6 - If it doesnt shows any kind of threats then you need to change your antivirus software immediately with some good one with the new version.

What is Antivirus?

Antivirus software (anti-virus) is computer software used to identify and remove computer viruses, as well as many other types of harmful computer software, collectively referred to as malware. While the first antivirus software was designed exclusively to combat viruses, most modern antivirus software can protect against a wide range of malware, including worms, rootkits, and trojan horses.

Modern antivirus software typically employ a variety of ways to identify a virus. Most antivirus software use signatures, identifying pieces of code found in a virus. Wild cards may be present in a signatures to account for mutations; modifications made to evade detection. Heuristics may supplement signatures. Instead of attempting to relate a virus with a signature, heruistic technology may look at a program's code or actions for potentially damaging code or actions. Heruistic technology may emulate a program in a sandbox, classifying actions as malicious or not. While heruistics may increase the sucessful detection of malware. However, a downside is the increased risk of a false positive; when the antivirus software incorrectly identifies a file as malicious. Programmers who write antivirus software could classify every file as malicious and boast 100 percent detection. However, the program would obviously produce numerous false positives. Instead, programmers must improve heruistic detection methods and signature detection methods, and attempt to find a balance. False positives can render programs corrupted, and possibly the operating system corrupted. In an recent incident, a faulty update issued to Symantec's Norton-branded security software in China removed essential files needed by the OS, on the grounds the files matched a signature. The incident left thousands of computers in China unable to boot.[1]

What the Virus $111.53 Antivirus software is a key security technology on todays end user systems. Current antivirus engines use two complementary techniques to detect malware. One is to statically scan potential malware sample files for certain patterns which are known ( malware signatures ). The other is to dynamically detect typical malicious behavior (e.g., modifications of registry keys, DLL injections etc.) upon execution of a sample. No antivirus product can reliably detect malware. Rather, all products are plagued by false positives and false negatives. An interesting approach to improve the reliability of detection is to run several antivirus products on a given malware sample. There are several online scanning services, that implement this approach. However, for performance reasons these services only use the static signature detection functionality of the anti virus products, and thus do not take advantage of the full functionality of current antivirus engines. This book explains how to overcome this limitation and to build an efficient online malware scanning service that fully utilizes the capabilities of current antivirus engines.

Crazy Boot (Computer Virus) $68.51 High Quality Content by WIKIPEDIA articles Crazy Boot is a computer virus that infects the Microsoft Windows operating systems causing no physical damage nor direct loss of information; it would be known as a hoax to some. If the host computer is booted from an infected floppy disk, this virus makes it look as though all physical hard drives have been lost. Crazy Boot spreads through unprotected disks easily. It spreads only on diskettes, not by file distribution. The virus resides in memory, it infects the master boot records of all physical hard disks and infects the boot sectors of floppy disks. If Crazy Boot is in memory, any access to the boot record is rerouted to a copy of the original boot sector. When the virus infects a hard drive, it makes a copy of the partition table (an important part of the system area), writes the copy, and deletes the original partition table. To read the partition information, Crazy Boot must be active in memory. If users boot from a floppy disk not infected by this virus in order to avoid it, all physical hard drives are inaccessible by normal means.

Ghostball (Computer Virus) $58.94 High Quality Content by WIKIPEDIA articles Ghostball was the first multipartite virus discovered. The virus was discovered in October 1989 by Fridrik Skulason. It infected both executable .COMfiles and boot sectors. A multipartite virus is a computer virus that infects and spreads in multiple ways. The term was coined to describe the first viruses that included DOS executable files and PC BIOS boot sector virus code, where both parts are viral themselves. For a complete cleanup, all parts of the virus must be removed. The term was coined, as prior to the discovery of the first of these, viruses were categorized as either file infectors or boot infectors. Because of the multiple vectors for the spread of infection, these viruses could spread faster than a boot or file infector alone. Ghostball was the first multipartite virus, discovered by Fridrik Skulason in October 1989. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.
