Okay, I've seen everyone in the world talking about this...
If your system hangs, Windows XP, and/or is very slow, and you do a Contro/Alt/Del to call up Task Manager and watch the active processes..you see iexplore.exe (Microsoft Internet Explorer) is using up to 90 CPU power (but you don't even have the software running?
That is the issue I tackled for four days now. Being an old DOS even CP/M fellow (pre-dos), I tried every program out there today...SpyBot, MicroTrend, Ad-Aware, etc.
McAfee download from my AOL, finally give me a hint, and I think I found the sucker. A block warning box kept coming in as McAfee scanner was running. It kept talking about "C:\Program Files\scvhostsvchost.exe trying to access the system and or dial out!
I used Windows Explorer to look (my normal setting is to see hidden files). There it was! A directory in Program Files called SVCHOST, with two files in it. I knew this Svchost should not be in the program files directory. I rebooted, because it would not let me delete it...in Safe Mode Command Prompt (F8 as system is starting). Went typing directly to the directory, deleted the .exe and .dat file found there and the directory name (Svchost). When I rebooted normally, iexplore.exe was never again in the Tack Manager Processes list...unless I ran it.
I think this is the answer to what everyone has been talking about.
Look for the HIDDEN directory with two files in Program Files that is Hidden. Svchost. Delete it!
P.S. I hope this made it go away for good. Don't know how I got it on three system notebooks...obviously, someone is trying to make folks lives miserable enough to uninstall Microsoft Internet Explorer and use another browser. ******** out there!
