Processes

[Guest]

I wonder if anyone can help with this one?

I am running XP, home edition version 5.1 on my PC at home (In Singapore).
With 785,776 KB of physical memory available to windows.

When I access the internet I find that is very slow.

My internet access is by wireless broadband, and when activated shows:
Signal strength excellent and speed of 11.0 Mbps

My question to you is about the number of processes that XP normally uses.

If I go to the task manager ( with windows explorer only open (I also have a
Norton personnel firewall 2003 running)) I see that there are 55 processes
active.

I am afraid that my PC might have been infected somehow and unofficial
processes are running on the machine therefore slowing it down.

Among the 55 process there are 7 processes called svchost.exe, are these
normal, or is it normal to have so many?

There are many odd looking preocess such as "webrebates0.exe" and
"backweb-1940576.exe" with I think look odd?

Any assistance on this would be appreciated.

Best regards,
Brian Walsh.

You can ignore the svchost.exe, thats a valid xp process but the "backweb"
looks abit dodgy. If in doubt do a Google for each of the processes, but in
any case do a virus scan regularly, run AdAware every few days and above
all, read!

That's not at all an unusual number.

It's normal.

Backweb is malware and should be removed. I'm not familiar with webrebates,
but that certainly sounds suspicious. Do you run anti-spyware programs like
Adaware and Spybot Search and Destroy regularly?

That is quite normal. SVC Host is an interface program to run a whole
slew of services on behalf of the system. They get started in groups,
hence the multiple instances. Only bother if Task Manager shows one of
these as taking a heavy CPU load all the time. If so, you need to
experiment in Control Panel - Admin Tools - Services and try
selectively and cautiously stopping services. If you find the CPU use
vanishes when you select one, double click that and set its Startup type
to Manual.

They do. Do a serious investigation for malware - see guidance at
