How do I fix this high CPU usage svchost virus or whatever it is?

After I log in my system slows to a crawl. Looking at task manager I see that my computer is experiencing high CPU usage. Looking more closely I see it's something called "svchost" is taking 100% of my CPU time. If I kill the process suddenly other things stop working. Is svchost a virus? How do I fix this svchost problem?

That's actually a composite question, based on several reports I've been getting recently.

Svchost is not a virus. In fact it's a required system component. You'll often find several copies of svchost running.

Svchost, or more correctly "Service Host" is a program that is designed to run other programs and "hosts" many of the system services in Windows XP. Several copies of Svchost run more than one service, which is why when you kill an instance of svchost several things on your machine might stop working.

So, why is one of the Svchosts taking all your CPU?

And what can you do about it?

How can I force a computer to sign out automatically?

Do have any idea how to force the computer to log off? The situation is that at work people don't log off and leave sensitive information on their screen.

It's funny, I ran into exactly this situation years ago. I was walking by my boss's office and happened to see some interesting information on his screen. Some very interesting information.

It was performance review time, and on his screen was a spreadsheet with all the review and salary information.

Needless to say when he got back we solved that problem quickly, and the same solution might well apply here.

Why does blocking a spam email end up blocking my own address?

I just received a spam email and when I added it to the block sender file, my email address came up. What's going on here?

It's very frustrating, but you're experiencing one of the many ways that spammers try to force there way into your inbox.

Here's what's going on:

How do I backup a large number of large PSTs?

I work with about 200 end users. Most are power users on WinXP, and most use Microsoft Outlook. Unfortunately, most do no clean up of their email, so their pst files are about 2Gig each.

What is a good way to backup all of these pst files? Burning to CD/DVD? Using thumb drives? Hosting their PST's on a dedicated file server? Getting them all huge external hard drives? Or should we simply copy and overwrite their pst once a week to a file server, so their email program isn't actually working from off the network everyday?

In the ideal world, we'd change user behavior to clean up their PSTs to make them more manageable, and we'd implement one or more of the backup alternatives you mentioned.

However we're dealing with the real world here, and need a real world solution.

One thing that concerns me is that there's typically a lot more to life than a PST. How are you backing up everything else?

How do I reformat my machine if I don't have a Windows CD?

I want to format my laptop. It has Windows SP with service pack 2 installed. I don't recall getting a Windows CD, so first how do I format and second can I do it without that setup CD?

The answer for most people is simple: no, you cannot. In fact, you should not if you don't have the Windows setup CD.

Yes, yes, it can be done without the setup CD, but I'm guessing you won't like what you end up with. Not at all.

Let's be clear on exactly what it means to "reformat" a machine.

What's the best media player?

What is the best media player to download to view attachments with videos, Real? Quicktime? Windows media?

How about all of the above?

The problem is that as the recipient you don't have a whole lot of choice. It's the sender that determines the format that they send you, and you'll just have to have a player that understands it.

And not all players understand all formats.

*** Popular Articles from the Archives

This article has been getting a lot of traffic this week. That traffic, and the current probable cause for the problem many people seem to be having also spurred me to write a new article this week you'll see above: "How do I fix this high CPU usage svchost virus or whatever it is?" (http://ask-leo.com/how_do_i_fix_this_high_cpu_usage_svchost_virus_or_whatever_it_is.html). But here's the original that still has many, many important points.

Svchost and Svchost.exe - Crashs, CPU maximization, viruses, exploits and more.?

I've discussed Svchost, aka Svchost.exe, in previous articles on Ask Leo!. Many people are witnessing a svchost.exe crash and it's actually quite amazing. Unfortunately there's no single point of reference for svchost related problems. Rather than answering one single question I'll try to cover a theme that can best be summed up as:

What's The Deal with SVCHOST?

*** Thoughts and Comments

I chose the Svchost article because a couple of days ago I noticed a big spike in traffic to that article. I'm assuming that more and more people are being bit by a problem that appears to be caused or related to Windows Update, and are looking for solutions. Hence the new article "How do I fix this high CPU usage svchost virus or whatever it is?" that tries to address the current state of affairs.

I've been lucky enough to avoid the problem, but it certainly appears that more and more people aren't quite so fortunate. Hope the information helps.

My publication schedule got knocked a little out of whack this week... I've been working my little fanny off on my wife's doll shop web site. One thing that's new and interesting is playing with creative uses of video to display merchandise for folks visiting the site. After seeing that video, a friend commented that back on my high school's career day doing video voice-over's was probably not high on my list of expected career choices.

I replied that that may well be but it was still higher on the list than "selling dolls" :-).

Happy Mother's Day every one!

'till next time...
