Well, you should proceed a bit more cautiously, as in addition to SIDs, you have many 404's listed in Google :
But they work on the main domain : -http://pc-war.sk/post13609.html
So it looks like you need to do something about your sub domains rewriting, looks like no .htaccess was installed for them.
So you should fix this asap, and install the zero dupe
to get rid of SIDs.
