Details 2up.6000 This is a dangerous memory resident parasitic encrypted stealth virus. It hooks INT 21h, and writes itself to the beginning of COM files and into the middle of EXE files that are executed or created. It compares the file names with the strings: AID COMMAND ANTI AV HOOK SOS TSAFE -V SCAN NC VC TNT ADINF AID and does not infect these files. While infecting, the virus creates the file OBJXCREF.COM, writes itself into there, appends the file body, and then renames to the name of the file that it is infecting. The virus copies, into a reserved system area of directory entries, the string: 2UP(C)1994 The virus also displays the text: Hello BOBBY ! (BOBBY-Trash Soft & Hardware) In some cases it overwrites the files with the message: +————————————————+ ƒ Attention all No smoking !
