I am running win xp pro,with zone labs,avg and adaware,but now when i startup the machine it gets as far as almost fully loading when a black box pops up with what appears to be a command that shuts the system down.If you can get to the box quick enough and click the close before the command line has finished its ok but if not it closes down.I have done all the usual checks which have drawn a blank,used the windows repair but its still happening and getting harder to catch the box.Any help much appreciated.
I have just tried insafe mode and it started up,looked in startup but unsure what should be there and what not,restarted and the black box came up again,its a black box with the usual close etc in rh top corner,it happens so quickly but i managed to see doc/settings/home/ shutdown,not sure if there was something between home and shutdown,its so fast to read
I have done all the scans in safe mode,still finding nothing,is it safe to go online in safe mode to do the online scans?.My husband says the box that comes up is like the network command box that comes up where he works when they start there computers up. It is as if someone has put a command on there to tell it to shutdown. What Trojan checkers would people recommend, i have run adaware,registry checker and spyware doctor.It has got that it is vertually impossible to startup properly,but no probs in safe mode.Thanks
I suggest you start again in safe mode, click start run, type msconfig in the box press ok and click the startup tag. Identify those items shown as being loaded into program files and ignore those in Windows Try disabling the program files entries one by one restarting each time to see if it fixes the problem. Try and identify those with entries which are unrelated to your anti virus programmes. If you disable one at a time you should do no damage and you can aleways go back and reenable if you need to.
When i deselect all at startup,it starts up fine in selected mode,i left just what i think is windows and it comes up with the problem.I have removed all recently added software,and online trojan scanner comes up clear as does anti virus software.Can i continue using selected mode or would this cause problems?My zone labs and antivirus appear to be running fine in this mode.
