Year 1988 is the year when appeared antivirus traders, who sold them very low 5 – 10 $. Some companies have tried occasionally to propel, but nobody was paying serious money for a potential evidence. Thus was given a chance for viruses like Stoned, Cascade and Jerusalem to spread without being detected.



However, IMB decided that we must take seriously viruses after he had a spread viruses like Cascade to Lehulpe and fould the predicament to announce his customers that might have been infected. In fact, it was not a serious problem but, at the time, IBM took matters into serous and as a result, the High Integrity Computing Laboratory in Yorktown was decided to begin research in this area.





At the end of 1988 it took place almost simultaneously several events: a large out break of Jerusalem in a financial institution; second – a British company called S&S held its first seminar on viruses theme, seminar that explained for the first time a virus is and how it works; third – held epidemic ‘Friday the 13th’.


One thing was clear to all institutes of financial, academic groups and individuals could easily cope with an epidemic, if they had the necessary tools. All you needed was an effective detection of viruses, but it was not available. As such, it was create the first Anti Virus Toolkint.




In 1989, a Scotish contacted researches from England and has communicated that found a virus in hard disk. He noted that called Datacrime and that he was worried that we will start again on the 13th of next month. When the virus was disassembling, it was found that any day after October he trigger a low-level formatting of the cylinder zero on the hard drive, which determine the most hard disks elimination allocation table files and let users without data.


Meanwhile, display name Datacrime virus. It was published an analysis of the effects of the virus, but they found that it was actually another virus, resident in memory. In America people started to call him ‘Columbus Day Virus’ (12 October) and was suggested that it was written by a Norwegian terrorist, not upset that Eric the Red discovered America, but Columbus. The only cure to eliminate Datacrime was running a detector.


In July, Scottish companies started asking IBM if viruses percent a serious threat. Datacrime can not exist, but the possibility exists that a firm becomes infected with Jerusalem, Cascade or Stoned. ‘What is IBM this threat?’, They asked. IBM held an antivirus program, but it was used only for internal use.


IBM had a dilemma: if it did not offer this software October 13 clients and if a number of computers would have fallen, his reputation suffer. In September 1989, IBM released along with a letter explaining that her clients what it was. October 13th fell on a Friday, so it was an event dub – Jerusalem and Datacrime. In the US, Datacrime was exaggerated and mistaken for one that is not so dangerous as this. In London, Royal National Institute for the Blind said it has had a stroke and had missed a wealth of important research data representing months of work. This event was investigated and indeed taped a small rash of Jerusalem and some files were deleted easily replaceable.
