Windows becomes unresponsive when opening My Computer

[Penoir]

I recently formatted my hard drive and reinstalled everything. At one point, I suddenly became unable to access my computer. I thought it had something to do with Dr. Divx 1.06, because it first started happening when I uninstalled that. I reformatted and it worked fine, but then it started doing it again. Before it did that, I got an error from Kaspersky saying that it was unable to update. This was the second time I had reformatted. What happens when I open my computer is that it just opens and has the flashlight search icon, it seems to open after a few minutes (about 5). I assumed it was Kaspersky, but I was unable to find any similar problems with that searching the internet. Strangely, by opening Internet Explorer and typing in D:, C: etc., I was able to access my drives without problems. Also, when I open my documents or something, and then click on the bar to expand it and look in other folders etc., it also freezes.

Acting on whim, I went into task manager and just started ending services. I really didn't know what I was doing, but I found that when I ended both svchost.exe that were listed as NETWORK, it enabled me to access my computer normally and stopped it from freezing. It also gave me the RPC error though that causes the computer to shut down in 1 minute. I had just set up a new network with a Linksys wireless-g router (wired connection with the wireless disabled)

Here are my system specs along with all connected peripherals

Windows Professional SP2 fully updated
Athlon 64 3000+ Winchester
DFI Lanparty UT NF4 Ultra-D
1gb Corsair Value Ram cas 2.5
Seagate 160gb 7200.7
Samsung 352b CD-RW/DVD-ROM combo
Samsung floppy
Gigabyte Geforce 6600
Fortron Blue Storm 500w
56k US Robotics V. 92 modem
HP deskjet 5550

HP Scanjet 5470c

DSL modem - Speedstream 5100
Router - WRT54G

My hard drive is separated into three partitions. C is used for operating system, D for non driver installs, E for storage

I formatted C and D on my last format, E was untouched.

Does anyone have any ideas? Thank you for any suggestions that you might have.

Update windows and do a virus scan.

Or you can run hijack this and post a log.

But I dont think that's a network question. It would likely be better served in a different forum.

That RPC/shutdown in 1 minute is Blaster virus. Probably got in before you got SP2 loaded? You're not using a public IP are you? You should be behind your router.

Thanks for the reply. I actually am using an SP2 slipstreamed installation disc, and hijack this didn't come up with anything. I think I may have been infected by my data area that I left intact.

How do I know if I'm using a public IP or not? How do I set it so it's behind my router? Forgive my ignorance, I know relatively nothing about networking and haven't really had time to read up on it since I set my network up. I just set it up with the default configuration.
