I am having problems with my Toshiba Laptop. Initially it had Vista installed, but I downgraded it using an OEM copy of Windows XP SP2 about 4 months ago. I have not really had any problems until about 2 weeks ago.
On bootup svchost.exe takes 50%+ of my cpu according to Windows Task Manager. For about 20 minutes, it is next to impossible to get any application to execute. After this 20 minutes, svchost.exe drops down to its normal usage level and all is well for a time. Then, at seemingly random intervals, svchost.exe will act up again for another 20 minutes or so.
Can anyone help me fix this?
FYI, I have done the following to try to resolve/understand the situation.
Windows Update - Windows is up-to-date.
CA Anti-Virus - Clean Scan.
Windows Defender - Clean Scan.
System Restore - Created Restore Point.
Malwarebytes' Anti-Malware - Clean Scan.
SUPERAntiSpyware - Found and removed 16 tracking cookies. No other issues found.
Panda ActiveScan - Incorrectly identified a couple of items. Other than that, it was a clean scan.
HijackThis - Ran it and have included the log file as an attachment.
