Solved text changed in ureadable symbols

[Kytka]

Vista, except icons 90% text was changed overnight in unreadable symbols = small circles, small lines, dots and squares similar to Marlett font. Web browser displaying lines with small squares and numbers in it. Scan and recovery disk found nothing wrong. Fonts folder is empty. Something deleted all fonts.
Please help,

Try a system restore point from a couple of days ago and also try virus/malware scans. Also try this: http://www.vistax64.com/tutorials/66978-system-files-sfc-command.html?ltr=S

If you can get into the advanced boot menu, this tutorial shows how to:

Try using Last Known Good.

It's a good idea to use ERUNT
ERUNT and NTREGOPT

in addition to restore point. It just backs up the registry.
It may not be malware. Could be your system font got changed to some weirdy outline font.
Anyway,post back if you can't do Last Known Good.

Thank you, for your help,

It was impossible to trouble shoot or follow any solution because the text was not readable...I lost my patience and reinstalled windows Vista, but one day ill find out why text changed in Marlett font.

If you can, it's a good idea to back up your system partition, registry and also have battery backup. If the situation should arise again then you'd only be reverting to the last image backup. If you make a couple a week, then you only lose a few days of modifications. Restore is a matter of booting the restore disc, then running the program to copy the image file back over the system partition. Depending how large your system partition files are, it can take less than an hour.

Also it's cool because once you test it and know it works, you can do stuff like try a new OS and if you don't like it, put the old image back on. Sometimes it's easier just to put an image you know works back on than to try to figure out what went wrong.

Macrium Reflect Free and Easus ToDo are a couple of good free image backup apps. You can find a list on www.thefreecountry.com
