unable open disk drives upon double click; capacity of each drive is reduci

Hi all,

I am facing a problem past two days. Don’t know whether it is a virus or not.. I am unable open any drives including C upon double cliking. But I can open/explore by doing right click. Worst problem is that there are thousands of .dll files created (starting from 00_1.dll to 00 00_14xxxx) in all drives including C/windows/system32. Each time I try to login I find my all disk space gettng reduced because of these .dll files. Also because of these files my comp is getting slower and slower and it is getting very difficult to do a complete scan also.

so do you guys think that it is virus/trojan attack.. If you have any solution plz post it urgently.

Thanks,
