Viruses are often isolated from the initial patient sample. This allows the virus sample to be grown into larger quantities and allows a larger number of tests to be run on them. This is particularly important for samples that contain new or rare viruses for which diagnostic tests are not yet developed. [citation needed]
The most commonly reported mechanism of infection involves receiving an email with a Microsoft Word document attachment that contains the code. The document is gibberish, and prompts the user to enable macros to view the document. Enabling macros and opening the document launch the Locky virus. [6]
Microsoft Project 2000 'Project' was an MS-DOS software application originally written in C (and some assembly) language for the IBM PC.The idea originated with Ron Bredehoeft, a former IBM S/E and PC enthusiast in the early 1980s, as a prank to express the recipe and all preparation for a breakfast of eggs Benedict in project management terms.

Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important variable that must be monitored.
Anti-virus software vendors can receive copies of files that were flagged by other scans but passed by their own engine, to help improve their software and, by extension, VirusTotal's own capability. Users can also scan suspect URLs and search through the VirusTotal dataset. VirusTotal uses the Cuckoo sandbox for dynamic analysis of malware. [8]
Anti-virus programmers set the EICAR string as a verified virus, similar to other identified signatures. A compliant virus scanner, when detecting the file, will respond in more or less the same manner as if it found a harmful virus. Not all virus scanners are compliant, and may not detect the file even when they are correctly configured.
Specificity indicates how well-targeted the test is to the virus in question. Highly specific tests pick up only the virus in question. Non-selective tests pick up other viruses as well. A 90% specific test will correctly identify 90% of those who are uninfected, leaving 10% with a false positive result. [13]
The damage to Microsoft was minimal as the site targeted was windowsupdate.com, rather than windowsupdate.microsoft.com, to which the former was redirected. Microsoft temporarily shut down the targeted site to minimize potential effects from the worm. [citation needed] The worm's executable, MSBlast.exe, [10] contains two messages. The first reads:
