Big Malware/Virus problem

Hey whoever reads and helps with this stuff, I'm here trying to help my friend clean up his computer because it is royally screwed up, AMD Athlon XP2600+, 512 mb ram and such, but running slower than my 700mhz duron. Anyways, i followed all he steps from the READ & RUN ME FIRST thread, and it took a long time, but i think i've cleaned a fair bit, however I ran into a couple problems during the process. First, spybot couldn't remove 66 items, something about memory use, I'm not exactly sure. everything else ran smoothly, but the homepage continues to revert to about:blank, and we're getting popusps whenever we go to a new page and such. Unclassified.Spyware.65 is also continually trying to reinstall, but i keep blocking/removing it but it keeps coming back. Included below are the Panda, and Hijack this log scans. It apperas my BitDefender scan is too big, and it wont let me post, just tell me what to do and I'll include that in the next post. Hope to hear back from you soon, Thanks

 

Download and run About:Buster 6.0.

Get any updates then run the utility, afterwards reboot and post the log with a fresh HJT log.

 

Hey, just dled about:buster, ran it and such, but it says "runtime error 6 'overflow'", I still tried to run it again, but got the same message, i restarted anyways and ran HJTL again, and below is new log, help is much appreciated

 

Please save these instructions to a text file in Wordpad/Notepad or print them out because we will be restarting in Safe Mode and you will have no Internet Connection.

• Download About:Buster
• Unzip AboutBuster.zip and it will install in it's own folder.
• Double-click on AboutBuster.exe and then click 'OK' then 'Update'
• Click "Check For Update" and then "Download Update".
• Click "Exit"
• Please Do Not Use It Yet.

Disconnect From The Internet, pull the cable!

Now, please reboot into Safe Mode!

• Please Double-click on AboutBuster.exe.
• Click "OK" then "Start" and then "OK" to allow AboutBuster to scan for all bad files.
• Click "Yes" when About Buster asks if you will allow it to shutdown explorer.exe.
• Allow AboutBuster to scan for all malicious files.
• Repeat the scan if it asks to do another.
  
• After the scan, click "Save Log". Post the log in your next post as it is necessary to make sure all has been cleaned
• Then Click "Exit"

After you complete the above, reboot back to normal mode and post the log from AB along with a fresh HJT log.
