I download remove virus programme but I could not open and run them. like comboFix & Malwarebytes, and now won't let me open avg web page or other helpful webpage. Could not go to safe mode either. I am using AVG 8.5 and it is wdw xp could not go to helpful website but being hackjact to other malicious page. It seems that I could not do anything becasue the registry being infected? sorry I don't know any technical term to describe or run the dot programme to show the problem Any advice please please, I just get on the internet in 2 days and haven't backed up all my personal file, so worry now.... If I reinstalled xp, would all my pre-factory installed things like 'nero' gone as well. Thanks in advance.
