You have not followed the ZHP Fix instructions properly, have clicked on "GO" to confirm the cleaning?
Run ZHP Fix again and insure you follow the procedure.
Have you, as I indicated before, ran ZHP Cleaner on the other computer? As I mentioned, since the DNS and Proxies were hacked, the other computer may also have been infected and contaminated the present computer or vice versa.
The reason you had problems with Chrome is because it was also attacked.
I also suggest that you urgently change your Wifi password.
You should have no more than one antivirus software. Antivirus software all have their own scanning engines and .dat files, they may come in conflict and create false positive reports and sometimes let malware through.
To answer your question, no, there is no antivirus software free or otherwise that will clean all of this malware. The best thing is to have one good antivirus, a good firewall and best of all, avoid taking risks on the net such as downloading torrents such as you have done. The best antivirus suites that I have used are not free, but they are worth it, they may warn you against reaching a site or downloading a file. Some malware can actually ruin an operating system or hack your data for a ransom.
Can you please upload a last ZHP Diag, I will tell you if AVG is correct.
