Could some body please tell me how to do it.

 

I tried the...

K2 Import / Export 0.7 + 0.8_alpha3 but when i hit the export botton it gives me a http://500 error.

 

Is there a way to acces the data base take what a need and reload it later on my new installation.

use phpmyadmin and copy all the _k2_ files out to a sql dump

Unless you know the extent of the virus examine them carefully

after putting up a new site use phpmyadmin to import the tables into the database...(untested)

You might try putting the entire site on a localhost and searching for all the occourences of the bad code to see what is affected

Eaisest to use a backup before the virus if you have one
