I have installed and run spy spybot search and destroy, as well as Malware anti malware. I have done three online virus scans with bit defender, panda anti virus and house calls. All three came up with some form of malware and according to bit defender i had a virus. They have all been removed. My own avg free edition, shows that my host file has changed. When I open up the file using wordpad, i see that spybot has added a whole list of names, so after reading through this list, it appeared legitimately ok. please can someone advise the next step. I have installed and run hijack this, and have a log file to post, but not sure where to do that. My pc is running very slowly, and i keep hearing a double click, and some strange noises intermittently.

many thanks in advance.

What kinds of malware did your scans find?

I have installed and run spy spybot search and destroy...My own avg free edition, shows that my host file has changed

AVG does not change your HOSTS file but it will alert you that the HOSTS file has changed since the last scan. What security programs are you using? Although malware can be responsible for altering the HOSTS file, some security programs like SpySweeper and Spybot S&D have features that can add entries to your HOSTS file and that action may be detected as a change. If you downloaded and used a custom HOSTS file or made edits that too would trigger a change detection. If you did not make any changes or do not have security programs with these features, then you need to investigate what the changes are.

The HOSTS file should not show as changed unless the user is aware of a program needing a change made to it and is aware that it is being altered. Protection softwares and also Malware's will often change this file so they can affect where a computer goes to on the internet.

This is one reason why the user on this system needs to look at the file to make certain that something didn't change it and if so determine if it is a good or bad change...

General system maintenance can change the file even when it isn't apparent by visual inspection. AVG uses a checksum to compare a file before and after and a minor change or correction to the file could have caused it to appear changed.
