This doesn't happen to me - for dat site - I've "played with the numbers" and have not had re-directs (although no content of personal interest).
Without being patronising,
I'm assuming that you have an Anti-virus installed.
But you
must also have at least one Ad-blocker and anti-Spyware installed and perhaps a HIPS (Host Intrusion Protection) - but you must run these progammes regularly. Another way - go to google and enter {How do I stop redirect} and you'll see much information.
I have no axe to grind - there are loads of free products on
www.download.com and other sites including
www.zdnet - www. tucows.com and I'm sure there are many others to be recommendeeed from other forum members (I'd like to hear about them - thanks).
Fr'instance - The following products are free and avail from Download.com ....
Spybot - Search and Destroy - Anti Spyware
AdAware v 6 - Blocks Ads and tracking
Prevx Home - Intrusion prevention
Safe surfing and best regards.
