I am a real novice so I apologize if this is a dumb
question, but why would there be 5 listings of
SVCHOST.exe in my running processes? I have run a /SVC
to see what was attached to each. I just don't know what
is legitimate and what isn't. I have been receiving
notices that my machine is sending out virus infected
emails, but my virus definitions are uptodate and say "no
viruses". something is going on I just don't know what.
The Baseline security scan says I have critical patches
missing, but when I go to critical updates page to
download it says I have everything installed. HELP!!
I will attach the log in case there is anyone more
experienced than me who might help.
Thank you in advance:
