There's a new Word macro virus going around that could soon be firing rounds at your PC.
Chronic (WM97/Chronic-A) uses a complex counting process to determine when and what specific payload to execute based on your PC's system date.
Chronic arrives as an infected Word document either by network share or via e-mail and affects users of Windows 95 and 98. Once a system is infected, Chronic will keep count of the number of times it executes.
For every 25 times the virus runs on an infected system, Chronic will execute a complex series of checks on the system date. Under certain circumstances, Chronic's payload can overwrite a system's CMOS settings. At the moment there are only a few reports of this new virus.
