I would really encourage anyone with any issues with their PCs performance to check their updates.I was getting very slow speeds and redirections last week but Norton was showing nothing except high usage alerts for iexplore, which can be indicitive of hacking. I was also getting constant redirects to either "win an Apple" or a "Juicy fruit " site. The web addresses came up as malware sites,and when I looked at some other forums they have reported the same problems as a few of us have had here, and very recently as well.
I ran all the virus ware I had plus Microsofts and found nothin at all, but on wednesday the attack was so servere assoon as I clicked on a thread ,it blocked me from using the keys so i turned the internet off. Again, after scanning nothing showed up so I spent ages trying various things, and eventually uninstalled my current iexplore and upgraded to Explorer 9.
Whatever Internet Explorer 9 has within it must have done something right because a dozen or so updates appeared for the microdsoft.net Framenet4 update. It seemed to take forever for them to install (at least two hours) so they may have been doing some "cleaning" up, but now everything is operating with really quick times and I haven't been redirected again on the RPF despite some lengthy posts and a hop around. Check to see if you have update KB982670 for Framenet4 on your system and the ten or so security updates for it after. It appears this upgrade did fail with some PCs when it was released so its well worth checking for in Updates history.Most people will have had this about a year ago but the few that may have missed this will thus left themselves open to problems.
If you're PC is constant busy ie the hard drive is chattering away after a minute or so on a site the chances are something is wrong.
