Parasite help

I am having problems with my pc - internet programs that keep coming back no matter what I do. I have run AdAware, Spy Killer, and HiJack This. Can someone please look at my log file and tell me if there is anything here that may be causing this? Thank you very much.

Thanks.....

Thanks for your help. The system seems to be running better, but I'm still getting the internet things in the background. I did install 550 Access, but have just uninstalled it. It's a site that comes up as "advnt". Sometimes 01, sometimes 05. It runs on start-up, but flashes by very quickly. I've searched all files and folders, but can only find the cookies it leaves behind, and even after clearing my internet files, it comes back on the next startup. Also, when I first open IE, the page comes up blank, even though the address bar says the page is open. I click refresh, and it fills in, then works fine after that. I'm not sure if the 2 are related. Thanks again for your help. LauraJ

 

Welcome to MajorGeeks.I honestly feel that you should do a scan with the Shredder,help clear up some malware download here http://www.majorgeeks.com/download4086.html

 

Ran CWShredder

Thanks so much - I did download Shredder and ran it - it said everything was clean except this: windows/sys_ai_client_loader.exe. It said it couldn't identify the file for sure, but it may be part of CWS.Contro.4. Do you know? Thanks again.

 

You were right!

I renamed the file and deleted it, and it doesn't appear to be anything I need, and for the first time, didn't see it loading in the background when the system re-booted. I searched the registry, and did find the "advnt" and the "sfondi" which I knew was part of it, as well as the
windows/sys_ai_client_loader.exe file - all in the same folder. Can I just delete this folder from the registry?

 

Good advice from Robo------- Laura why don't you leave as is for a week.It's not doing any harm. If no problems delete si ation. Better to be safe than sorry.
