Ok so im running windows 7 ultimate and every once in a while my anti virus thing pops up saying that it blocked a threat on my laptop but when i click clear infected it says that they're in accessible or not available or something. There is this other problem too that i think might help, when i am using google chrome and i search on google i will click a link to the specific one that i want and more than half the time it will redirect me to flurrysearch or some other random website, please help as this is getting annoying and i don't want to wipe my laptop again.
