|Thanks to Jabuck|
Who saved me a sh#t load of time.
I have been trying to fix this problem for DAYS.
Basically, I was getting redirected to blank page or fake Microsoft security centre page with message "your computer have been invaded by viruses"
then a link saying "download anti-spyware now".
Anyway, I had tried many things like running anti-spyware programs in safe mode and so on. It was taking days and I was considering doing a clean install.
Nothing worked until I stumbled acroos this forum and Jabuck's advice about downloading HostsXpert.exe file.
I ran it and it fixed my computer in seconds. I couldn't believe it.
So thanks again Computing.net and JaBuck
