I've been having problems with my laptop for a couple of months, and have been struggling with it myself, but it only gets worse. I get "corrupt .exe file, please run chkdsk" messages in the notification area when I run any program, though the programs usually run just fine. I haven't been able to run chkdsk without resorting to the Windows XP disk form the computer manufacturer, whether I do it through windows or the command line. Windows tells me that it can't run it because chkdsk is already scheduled to run; Command line tells me the volume is locked, do I want to schedule to run on next bootup, and then doesn't run on bootup. Yesterday I ran it twice from the boot disk, and it says it fixed one or more errors each time, and the only apparent affect was that it managed to get through phase two on a disk check through Windows before stalling, when previously it had stopped at phase one. And then I got the BSOD five times and had to power off and on again to get Windows to start (and it had never taken quite THAT long before). I was suspecting either a virus or a dying hard drive, but I ran the manufacturer's diagnostics on the harddrive about a week ago, and that indicated no problems with the hard drive. I have been focusing most of my efforts on malware removal, and have run through your suggested removal programs several times over the last couple of weeks ago and removed some viruses and malware in the early scans (though not many), but the problem appears to be getting worse, not better. I am running a Dell Inspiron 1520 with Windows XP/SP3 I attach the latest logs from Malwarebytes Anti Malware, Super AntiSpyware and Hijack This.
