Its a nasty piece of work, attacks via root 0 access and stops services, infects them, and restarts them.
If you remove the main infector (being those 2 files) it causes the other services which are infected to stop working (no doubt cause the infector loads its own library which the other services need). So it causes a 1 min shutdown.
So yeah reinstall of Windows is needed in this case, thats until AVs catch up.
The shutdown can be averted with a "shutdown -a" command though. It ignores crashes at the cost of whatever functionality will be lost.
With that being the case, i whole-heartedly agree with Pwiz.
As much as i like technology, if my job included the use of a PC or even an office i would love to get a virus that could render my working equipment unusable.
And thats what made me Laugh at PWizards comment,i never thought of CHU getting that Virus.
