I'm new here, sorry this is my 1st post, i'm more of a lurker around these forums, anyway...
I have a problem, my computer started acting up yesterday, first of all I use google chrome by default, the first thing I noticed was when I started my computer up this morning, I had internet explorer on my task bar instead, I didn't make that change, also my computer was being abnormally slow. So I figured I'd try running McAfee, but it does not open up, I tried downloading other anti virus programs like spyware doctor, avg, and a free trial of norton, but it does not let me install any of those, they stop in the middle of installing and say that I have no internet connection, when in fact I do.
It does however let me run google chrome, but it doesn't let me go to many places, for example, when I go to www.gmail.com it shows a red slash accross the "https:" part of the web address and then the whole browser screen turns red and reads " invalid server certificate, a request failed because the server certificate was invalid" it does this for a handful of websites I've tried visiting. I guess I picked up a virus of some sort or something, I'm not sure where to go from here.
I have already tried starting my computer in safe mode, but it makes no difference, it does not let me run any type of virus scan. I don't know what to do from here.
Any help is much appreciated. Many thanks in advance!
