Hi,
My computer has developed a problem in the last few days. Usually only between the hours of 5pm and midnight (GMT) my broadband connection is hijacked and used to upload a constant stream of information. If I disconnect, the CPU runs at 100% and makes the system a little unstable unless I reconnect. Multiple cscript.exe files are launched every second or two in task manager. Having looked around the system the following files keep on appearing - in c:\WINNT\System32\wins I get a svchost.exe and WMI.vbs. In c:\WINNT\System32\WBEM\Logs a wbemprox.txt file. In c:\WINNT\System32 I keep on getting Perflid_Perfdata_1b8 (or 1bc or other combo) files. In C:\Documents and Settings\Default User\Local Settings\Temporary Internet Files\content.IE5\MBWSCNE3\ a Test[1] file keeps appearing. Also I have an idea that win.cfg in c:\WINNT and a few other security files might have been altered. I've managed to delete the offending files but they keep getting reinstalled. Spybot and Ad Aware can't find a thing, nor could PC Tools Anti-Virus. I've around about exhausted anything I can think of to eliminate this, further suggestions most welcome!
Cheers,
Mark
