A few weeks ago i downloaded flash codec from a website, and ever since then my search engine has been redirecting me to random advertisement sites. Then a few days later, my computer started to freeze after about 20 minutes of use. This continued to happen until i was not able to use my computer at all. Once i logged on, i could look at my desktop, but i could not click anything. After this happened, I went into safe mode and created another user. The new user still redirects my Google results, but i am able to use it without the constant freezing. Can someone please help me out, i don't know what to do anymore?
