Have a PC that was just reloaded with WinXP PRo SP2 and all fixes. Its performances has gone down the toliet due to several mystery processes running. They are SL304.tmp, SL4B2.tmp and the like. Have Spycatcher Express running and COmodo Firewall and neither appears to have caught anything. Use may have allow something....I do not know. They are taking up 100% processor utilization. There are 4 of them. Any idea what these are?
