Hi,
0) it seems you have the AV-Monitor /resident shield/Vshield of BOTH avast and Mcafee running simultaneously ..
That is BAAADDD!! disable one of them permantly
(or if our subscription to mcafee has run out, uninstall Mcafee completely)
1) uninstall new.Net /newdotnet via control panel -> Software/programs
2) PAUSE avast's ResidentShield = AV-Monitor BEFORE you do a scan with
Ad-Aware and cwshredder or other scanners
-> Fix everything found
3) do a scan with Trendmicro's and then RAV onlinescanner (with avast still paused); note the found virusnames exactly, and look up info for Trend here:
http://www.trendmicro.com/vinfo/virusencyclo/and for RAV results here:
http://www.virusbtn.com/resources/vgrep/index.xml(select Gecad RAV in the VENDOR menu, enter the found trojan/virus-name and follow the red links to the instructions on removal to trend, mcafee or symantec)
if you don't succed there, tell us for each finding of Trend and RAV:
- exact virus name and exact location (full path/folder/filename)
4) rerun spybot and ad-aware again, best in SafeMode (F8-Boot); fix everything found
if something keeps occuring there, report here what it is
5) remove everything in the hijackthis-log from O16 DPF ... that you don't know or need
6) is www. btbroadband. com/ your desired startpage ?
if not: fix it
and then post new hijackthis-log
