It looks like a issue with screen resolution that is being set inside Virtual Box OS of Windows XP.

Just try to set the max screen resolution possible and it will be fine.

Thanks Avi and sorry it is not working.

Actually i think i have not specified the problem correctly.Not only virtual text size become large my other applications like VLC media player,Secusimple secure my files and some more software's text became large in size.Due to this everything starts overlapping.
You can see it clearly from the Secure My Files interface pic that i have attached with the above post.

Please help me.
