I have a Toshiba laptop running Win 7 (64bit). Lately the computer freezes up in less than five minutes if running in normal mode, leaving only hard-boot option. When restarting, I go to "Safe with Networking" mode, and everything seems to run fine, even internet. I have repeatedly run scans from: Malwarebytes; SuperAntiSpyware; SpyBot; Windows Defender; CCleaner; Periform FixCleaner; TDSSKiller, and probably another half dozen. I have reset the Hosts file, and recovered to a reset point established back in December, before the current problems began. Nothing has solved the problem (any threats found in the various scans were removed, but that had no effect on the current problem). I suspect, from the scan results, that the problem is not malware. I think there may be a corrupt or damaged file or process somewhere in the system. The OS is factory installed, and the laptop did not come with a Windows disk. What's the best way to clean this up? Thanks for any help.

1) What types of "threats" were removed?

2) Open msconfig and on the General tab choose "selective startup" (uncheck all three items) and reboot. Does the problem still occur? If not, start adding items back to msconfig one or two at a time, rebooting after each change, until the problem reappears and you'll have identified the offending process. This is clearly a time consuming procedure, but it is the best way to determine if some process loading with the system is the cause of your problem.
After you've isolated the cause, do not use msconfig to permanently disable the process. Instead, if it is a service go to START - RUN and type: services.msc (then press enter) and disable the service OR, if it a program, you can download & run a simple app such as Mike Lin's Startup Control Panel (http://www.mlin.net/StartupCPL.shtml) to enable, disable, or otherwise manage startup programs.

Mostly Adware Tracking cookies. There were a few items that were identified as "Trojan Agent".

Thanks for the help. I will begin the process of elimination suggested, and follow up with results.

To reduce some of the isolation test, UNcheck half the boxes. Reboot. You can repeat this process by removing half of the booting files at a time. You can see if the problem is in "which half". So, if you have, say, 40, halving them each time would be 20 then 10 then 5, etc. Saves some time.
