Download HijackThis (current verison is v1.99.1)

or here (Alternate 1, a self-extracting zip file)
or here (Alternate 2, an *.exe file)

Make a new folder to put your HijackThis.exe into.

(Anywhere on your hard drive is fine other than your Desktop or the Temp folder. Suitable examples are:

• C:HijackThis
• Crogramshijackthis
• C:WindowsMy DocumentsHJT

but feel free to use any name.)

Extract and save the HijackThis download to the new folder you made. Then navigate to it and run HijackThis from there. (This is to ensure it makes the necessary backups for recovery if fixes are made) Then, doubleclick HijackThis.exe, and click Scan.

When the scan is finished, the "Scan" button will change into a "Save Log" button. Press that and copy & paste its contents in your reply. Most of what it lists will be harmless or even essential, don't try to fix anything yourself.

Here is Hijackthis log

Note : process.exe is detected by some antivirus programs (AntiVir, Dr.Web, Kaspersky) as a "RiskTool"; it is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

process.exe file is missing from that last dowload?

It is in my download...

May want to disable any Anti-Virus programs, as it may delete it.

Still appears to be missing. I even re downloaded it again after switching off security.
