Very slow computer [Solved]

My office computer has become extremely slow. Scans with corporate antivirus software reveal nothing. Thought I'd try this as a last resort. It may just be the computer is too old.
Hijackthis log below.
Thanks.

Hi pzinser,

My office computer has become extremely slow. Scans with corporate antivirus software reveal nothing.

Since you are saying that this is an office computer I think it would be in the best interest of you and any of your clients to have this taken to your IT department.

As per our Terms of Use:

We offer free computer help and tech support for home and personal use. We are not here to support others that work for profit, or to support/replace your company's IT department.

There may be restrictions and modifications installed on such machines that could be damaged or altered by the actions we take to remove Malware.
Any infection could jump terminals in a computer network.
There may also be legal issues regarding any loss of business data that I do not wish to deal with.
Some people who come here use their computers for work, and the computers may contain the patient records of a physician or the financial records of an accountant's clients or credit card and bank account information of their employer's customers.
There may be tremendous risks and legal liability for such users for not fully securing the computer. We will not know this unless we ask. We do not want to be accidentally putting those we help in vulnerable positions for law suits.
Business factors outweigh technical factors in making the reformat and reinstall decision. Sometimes friends give missing CDs or lack of expertise as a reason for not doing a reformat and reinstall.
The cost of replacing missing Windows XP and MS Office CDs and getting an Microsoft Certified Systems Engineer to come in for 3 hours to do the reinstall and apply all the critical updates, is trivial compared with the potential cost of a multi-million dollar lawsuit for breach of trust if confidential client or patient information is disclosed.
