Try this should assist also svchost.exe and winlogon are legit files scvhost isn't
I am also getting a little yellow shield symbol down by the clock on my desktop that tells me its downloading updates, but i updated thru microsoft today. When i go to turn of, there is a change in the apperance of the screen, and a little shield over the turn off option. These things do not look legit, and I dont know where they are comming from. Are they symptoms of the infections i have? I see weird things as spybot is going thru files like golden casino, lots of other casinos, and the virtumonde. It takes spybot like 30 minutes to scan thru all the casino and virtumonde files. These are not places i have ever gone to, yet it shows up.
I can relate having the same problem. DLL s svchost winlogon sent computer int three times and they say nothing is wrong with it . Have you had any luck , im in need of some advice. Its like I have sixty four bit thirty two and vista.
