Burglar has anti-heuristics mechanisms. Burglar checks for and does not infect Windows programs or programs which contain 'V' or 'S' in the file name (covering programs like VIRSTOP, SCAN, VSHIELD, MSAV, NAV, CPAV etc).Since Burglar is resident, a clean boot is necessary before disinfecting and infected hard drive. Burglar contains programming error, which cause it to occasionally corrupt EXE files. Such programs do not work and they can not be disinfected.Burglar contains several bugs, and it can cause problems with several memory managers.Burglar was found in the wild internationally in January 1996. It has been spread in an infected version of a demo called 'Dawn', in a copy-protect crack for a game called Dune 2 and in a pirated beta of PKLite v2.00.
