when i visit a website address, within 2 seconds of being in the homepage I am directed to another webpage full of advertising.
I cannot seem to visit the web address i actually want to view.
Why is this and what is causing this to happen? How can I prevent this happening in the future?
You have been infected with spyware. The specific type that’s causing this problem is known as a page hijacker.
Unfortunately a page hijacker indicates you are almost certainly infected with other spyware.
We have instructions on removing spyware but keep in mind your infection is probably quite severe and may require expert assistance and possibly even reformatting your computer.
We would urge to change any PINs and passwords you have used on this computer as they may have been compromised. Do not do this on the infected computer.
