I've been asked to fix a laptop, which has had at least some malware (I think it's called Andromeda or similar) and at least 1 trojan.
Please note this is a home used laptop, it's not used for work and I'm fixing it at my home.
I have removed their trial of McAfee and replaced it with BitDefender Internet Security 2015 on their W8.1 machine.
BitDefender realized there were issues and informs me it has fixed then.
I also removed the Andromenda from the preferred search engines in IE and Chrome.
However, the issue is now that if I load a site which isn't SSL it works. So, www.bing.com works fine. However if I then click from the bing search results to a page with SSL, it renders the page without the CSS (and images). This means I can't use Google, which is their preferred search engine.
When loading an SSL site using Chrome, I get a very scarey message that it's not safe or secure and that attackers could do something nasty! According to the Chrome site, this means:
The site uses SSL, but Google Chrome has detected either high-risk insecure content on the page or problems with the site's certificate. Do not enter sensitive information on this page. Invalid certificate or other serious https issues could indicate that someone is attempting to tamper with your connection to the site.
The computers time and date are correct.
There is no option to re-install the OS sadly. They have a cat which has clawed the cert on the underside of the computer!
I'm not sure what I can do to fix this SSL issue in all the main browsers...
