HIJACK THIS LOG, C:\pagefile.sys?, PLEASE HELP

I have ran both Spybot and Adaware. I followed that up by running NOD32 Anitvirus. I have also ran The Cleaner to find trojans. I find nothing, except in NOD32 I get this message: "C:\pagefile.sys - error opening (file locked) [4]". I'm not sure if that helps, but it's all I can find.

The problems I'm having is that when I open up Internet Explorer, "about:blank" loads w/ a piss-poor search engine. Our homepage ALWAYS changes, and half the time we can't even open up normal web pages w/o getting a search engine and about 5-7 pop-ups.

Our internet use is very important to us, as we must place orders every 15 minutes, every day. Please help us, it is hurting our business. We believe an ex-employee did something to this PC, yet we're not sure how.

PLEASE HELP!

 

I'll give it one more chance before we have to call in the specialists.

Please, PLEASE save us the money... we sure do need it!

 

I guess I did something wrong, since it's been almost 4 weeks... CheekyMonkey, CdS, ReedTire. It only cost us $200 for a whole half hour's work of some pimply-faced 16 y/o to restart our pc in safe mode and fix it.

Again, thanks.
