Recreatable: dexplore.exe acts like a malware

[Guest elburze]

on My laptop dexplore.exe acts like a malware. Steps to recreate:

1) open Visual Web Developer 2005 [windowsXP home]

2) go to help menu and click “how do Iâ€Â

3) help window opens, but the mouse pointer icon alternates fast between

thinking and idle icon

4) open task manager, and I see dexplore.exe takes 70% of CPU time and never

ends even after 10 minutes

 

note: This is recreatable. If I open task manager before the step1, then

dexplore.exe stops taking CPU time after 2 seconds; so, seems to me it should

be virus/malware. What should I do about this?
