Post HijackTHis log.I am sending the log.

[Saving space - attachment deleted by admin]Nothing dangerous there.

Go Start>Run ("Start Search" in Vista), type in:
sfc /scannow
Click OK (hit Enter in Vista).
Have Windows CD/DVD handy.
If System File Checker (sfc) will find any errors, it'll ask you for the CD.
If sfc won't find any errors in Windows XP, it'll simply quit, WITHOUT any message.
In Vista you will receive the following message: "Windows resource PROTECTION did not find any integrity violations".
Thank you for your QUICK reply.

I will check with the sfc utility and will get back to you with the result.

If you don't mind, can you tell me how to check the log file to verify whether my system is in good condition or not?XP doesn't produce sfc log file.Sorry, I am talking about Hijack this log fileAs I said, nothing strange in your HJT log.ok
