Google's security certificate not trusted

March 29, 2012 at 08:05:55
Specs: Windows XP
Whenever I go to add an extension via the google chrome webstore, it loads up a page titled 'security error' which explains that the security certificate is not trusted. Also, if I try to search anything on Google, it either loads up a page that says 'access to proxy requires some authentication' or it loads search results that have nothing to do with the search topic. The Google homepage in question brings up a Google homepage that looks the same as the REAL Google but has slight differences (i.e different sized text) so there is obviously something dodgy going on. I had this problem a while back which resulted in me having to edit a txt file and get rid of a load of websites but I can't remember where. I'm pretty sure it's one of those viruses that hack google (or creates a similar looking site) and redirects you to random sites.

scratch that! the problem was with the hosts file located in c://windows/system32/drivers/etc/hosts and to fix it i went to the microsoft website where there is a fix that resets your hosts file to the default one, thus fixing the problem.

The fix can be found here at the microsoft website

Now I can search on Google fine and have no more issues! =)

Download and run malwarebytes from this link:
As the host file being changed in the first place means you have an infection of some kind.
Update and remove anything malwarebytes finds. Include the log in your next reply if it finds anything.
