Hi Recently I had a problem with my computer spontaneously rebooting itself. This seems to have been sorted (for now at least) but I am obviously concerned as to the cause. I have run all the spyware/ anti virus software I have (AVG Antivrus/ AVG Antispyware/ Adaware/ Spybot Search and Destroy) but whilt attempting to run Hijack This the computer wouldn't allow me, and acted as though it had partiallly logged off before returning to my Desktop. The same happens with CCleaner. Even when I try to access some websites wth a link to Hijack this, the internet shuts itself down. I can nether uninstall or reinstall the programs as anytime I go near them the same thing happens! HELP!!!!! Thanks PS I have had to type Hijack THis as two words as if it appears as one, my computer shuts down the webpage!
