Is this a virus?

A few days ago I started getting lag when opening files in my shared
folder. I only get lag when opening files from this folder on this
hard drive. All other files on the hard drive open and run normally.

A few days ago I had my computer on transferring files when we had a
power outage. Could this be the cause? I ran disk defragmenter and
did a spyware and virus scan with Bullgaurd and Spybot. Nothing was
detected. I also cleaned my registry and cookies. None of this
helped. I'm wondering if somehow my drive has errors that the
defragmenter didn't fix or if this is a virus or spyware that is
evading detection. Even files that had been downloaded much earlier
before the power cut are lagging upon opening.

In Taskmanager I noticed svchost is listed 5 times. I don't know if
this is normal but I don't remember this from before when my computer
is idle. Any ideas on what could be causing this?

Are you accessing the files via the share or via the the local hard disk ?

That's BullGuard AV ? If yes that's an OEM of BitDefender AV software.

Having 5 copies of SVCHOST.EXE is normal. What is important is NOT the number of copies but
where they are being executed from. They should all be executed from %windir%\system32 if
SVCHOST.EXE is executed from a different location it is a sure sign of a malweare infection.
Software such as Sysinternals Process Explorer is good for identifying the fully qualified
path of where a running process has been executed from.

Thanks David. I'm accessing the files from my hard disk locally. That
is, the shared folder is a folder on my hard drive that is specified
for sharing but is on my drive and not a local network.

These drives are in RAID 0 to act as one drive. I'm running Windows
XP I forgot to mention.

I tried that program and it shows all five instances are coming from
windows. I ran chkdsk last night. It took a while and I left it to
finish. When It was done I tried and found the same problem. I
downloaded the trial version of Bullguard which gives you a few months
of usage. I also did the same with AVG. Both of these virus scanners
turned up no results. I'm going to try another spyware scanner to see
if Spybot is missing something.
 
When I start to lag I open up Task Manager and see that explorer.exe is
taking up 99% of the processor.

What I do is end the process and then start explorer.exe back up
manually. I don't know why it's lagging on files it should run fast
and normally will.

the lag started. Selecting a file for copy also produces a seemingly
endless lag.

It doesn't sound like a virus but an OS related issue.

If SpyBot S&D v1.4 doesn't help... I would suggest posting this in;
