I have been trying to block spammers using the MS junk e-mail filter options with maybe some success, but there are websites the filters will not block as well as pop-ups that cannot seem to be stopped. One is from doubleclick.net, but that is only one. Have tried searches and found a different method that apparently is suppose to somehow bounce the e-mail or ad back to itself using the 127.0.0.1 IP address (don't know if I am using all of the terms correctly).
So far have found that the hosts file is responsible for matching "files" or text against IP addresses at C:\Windows\System32\drivers\etc and the "hosts" file is there. Had been suggested to rename the "hosts" file to "hosts.txt" so additional files or websites could be added. At first only had 127.0.0.1 local host or something like that. One time was able to add 2 or 3 websites and apparently saved because next time I checked they were there. Now I get the message that "access is denied" when I attempt to add additional websites.
Background: Win 7 Pro, sp1 OS. Have previously had an infection that was a mess, but "BleepingComputer" help me get out of that or as much as I can see. Am the only user and think I am set as administrator, but that doesn't seem to help. Have tried to copy "hosts", rename it, make a copy and add websites to the copy and paste that file, didn't work, then tried to save the copied file and then paste it over the original, that also didn't work and so long and short is that I cannot save any additions or changes now, "access is denied" Tried again going to properties to uncheck "read-only" because that had been set; still did not help.
So, if the technique to use 127.0.0.1 to return the e-mail or website against itself works, then I don't know how to get the new entries into the "hosts" file. Any help, suggestions, things to try would be very much appreciated.
