Wasn't trying to hijack this thread DavidR. I have the same issue. most places you post the same issue in the same thread, not start a new thread per person. I only posted and replied to help myself and others.
donjuangirl here is how I fixed the 2woody77.com.tw from popping up. All software was overlooking or will not remove since the file became system protected. your going to have to do this manually.
First your going to go to control panel and open folder options, clk the view tab, tic show hidden files and folders under the hidden files and folders. clk apply close that out.
open my computer, clk c: clk users, clk the folder name of the profile you having this issue with here we are going to use wali, clk temp, In there you should see the file thpm157572159625012743.tmp this is the file you need to get rid of.
1st I deleted everything in my temp folder. that file would not delete somehow its protected. I used unlocker to delete the file did a reboot and no more attacks.
you can download unlocker below:
