Plz any suggest me the virus free link to download driver for integrated cam for Dell 1558???

 http://support.dell.com

 Save all your files, reformat and if you or your friends has fios or comcast you will get free internet security download it.

Do not open attachment if you are not sure and do not poke any web that has high probabilty of transferring viruses.

for drivers, go to dell.com and enter your model number. Follow onscreen instructions, you will get one right there.
Free antivirus:
1. Avira free version works well - but sometime , it detects virus in simple script too.
2. Avast- it may make you computer significanlty slow when OS loads. It can scan virus during boot time.

Hi,
Most probably you just need a software, driver should be just USB driver and already included on your windows. I could not find the driver itself, but here is the link for webcam central for studio 1557 (not 1558 though). Give it a try. and good luck.
Hope works.

If this does not work, You should be able to get it directly from Dell.
Just go to Dell site, and enter your service tag then you should be able to locate all the required drivers and if there is any update on driver you should get it from there as well.

In fact, Dell is very vague on listing drivers, you will have hard time looking it just going through model number, better try with service tag.

One more input:
follow the suggestions on this link.
