Worried systems managers are facing what is thought to be the first virus to integrate with NT's security protocols. Found in the wild, it is called WinNT.Infis and acts as a system driver. It resides in the memory and will infect files in systems running NT4 with the following services packs – 2, 3, 4, 5, and 6. Although not particularly destructive, WinNT.Infis will corrupt programs and invokes a series of NT application error messages. MSPAINT.EXE, CALC.EXE, and CDPLAYER.EXE are all likely to be rendered inoperable by the virus which will install the file INF.SYS in the /WinNT/System32/Drivers folder. The virus was spotted by two anti-virus companies – Kaspersky Lab and Central Control. A fix for the virus is available by clicking here. ®
