Hi kavos1234,

First of all- don't worry about being new to the whole "online support" thing, or being new to our site in particular. We'll answer any questions that you have, and will do our best to get your system clean.

There's one thing you need to take care of before we begin though:

C:\Documents and Settings\calvin\Local Settings\Temp\Temporary Directory 1 for hijackthis[1].zip\HijackThis.exe

The log entry above indicates that you are running HJT from within a Temp/Temporary folder. Please do the following:

Create a folder outside of any Temp/Temporary folders for HJT and move it there now. A folder such such as C:\HijackThis or C:\Spyware Tools\HijackThis will do.

One of the normal steps in eliminating malicious programs is to entirely delete the contents of all Temp folders. Given that, if HijackThis (and other data that you care about) is living in those Temp folders, it will be erased along with everything else!
Temp/Temporary folders are just that- Temporary. They are not meant for permanent storage, as their contents are often delete in the course of troubleshooting, by running disk clean-up utilities, etc.
