4 files appeared on desktop recentIy.Can't find any info HELP 1)CA2JCFHEB 2) CAEZCT49 3)CAN6T8H3 4)CARQ0F3P

Cannot ID. Cannot delete, cannot uninstall. Spent hours trying to ID but unsuccessful. Does not appear in add/remove programs. Does not appear on independant uninstaller (Your Uninstaller '06). Unable to locate or ID via several search engines.Don't appear to be active??? ie, do not appear anywhere except desktop. In short, they appear to be permanent residents that don't respond to ANY commands. I run frequent anti- spy, anti-virus and anti-adware scans + firewall, various other forms of protection but they don't show up. Need Help. Anybody know what they are/how to get rid of. No change when operating in safe mode. Cannot move to file, anti-virus will not run scan on specific items and full scan does not pick them up. OE Windows xp sp2. Hovering over icon-shows 0 bytes? System sluggish, crashes frequently, cannot find source, could this be the problem?
