Does anyone know what the webnut.exe process is? It seems to be taking a lot of CPU processing power on a machine running Windows XP. The machine has been running much slower than usual lately, so I ran spybot search & destroy. It found a bunch of stuff that it said it repaired (except for DSO Exploit that it finds every time). But suddenly today the machine is so slow as to be unworkable-five to ten minutes just to open a control panel window for example. Any ideas on what I should do? Or any ideas on what else to look for? This machine was running McAfee anti-virus until about two weeks ago when that program couldn't run because it said it couldn't find a file it needed. I could really use some help. If the security section isn't the best place for this post, just let me know. Thank you.
