Hi Good News,

The issue is now fixed, the problem was an explorer not running automatically while loading OS causes blank screen after login and if you add it by manually in task manager it loads windows explorer successfully. After user permission setting done by one of my co - worker, it works fine. Hence I am happy with the solution for the issue blank screen , but still I am not confident on my system files and suspeting is there any virus.

Could you please let me know what can I do for to make sure my system is 100% secure is not affected by any virus.

Is this a Corporate/Government/Small Business/Institutional computer or used in that kind of environment?

Apparently the issues were resolved?

Hi Tashi, Thank you for your assistance

Yes the problem was resolved.

But I need to know how my system was infected? Whether the issue because of any virus? If so I need to remove it from PC.

If it is not because of virus then what is the reason to cause a blank screen?


System information:

1. it’s my personal laptop- Dell Vista Home Premium.
2. 32-Bit processer

Many Thanks
Ravi

Hello ravitheja,

Only the person who was on the computer might know how or when it was infected. ;)

The symptom described can be caused by several factors, for instance;

If the machine is a personal computer showing signs of infection and you'd like someone to take a look at the system please start a topic in the Malware Removal Forum (http://forums.spybot.info/forumdisplay.php?f=22)

First see that forum's FAQ which also includes instructions in post #2 on how to provide a preliminary DDS log, which is used for analysis.
