Hi, Im new here and Im in trouble.
When I tried to open my email today, my browser told me that I am infected with sirefef Gen C. I also realized that I cant access pretty much everything that is password-based. e.g fb, twitter, college portal
I tried installing microsoft security essential as suggested by the browser but the installation could not complete. It says something about 0x80070643 error. Im pretty sure that I don't have any other security tools that might interrupt the installation.
What do I do? Your reply is very much appreciated.
