For the past month I have had google links redirecting me to other sitess. It will do this for about weeks, until it eventually causes my computer to have tons of errors, and things disappear, making the reboot it, go into safemode, and select a past restore date. After I restore it to before the issue occured, it still happens. Is there anyway to find out what exactly is causing it, and get rid of it, without paying to upgrade my Norton? If not, is it a guarantee that if I do upgrade it, that it will take care of the problem?
