Hi, hoping someone can help me. I have been having big problems with my computer freezing, rebooting by itself etc then today my AVG antivirus wouldn't start and I kept getting error messages regarding AVG kernel. Every time I open any program I get the box saying "whatever program" has encountered a problem and needs to close. I have tried to remove uninstall AVG and then reinstall but I can't even uninstall it..it keeps saying installation failed. I have tried scanning with my other programs like adaware and AVG spyware but they are not working either. I downloaded spybot to try but when I click to open it it says something like this program has changed itself and is not meant to do this. I have zone alarm firewall and this seems to be working OK. I don't know what to do next. Can someone pls suggest something to help me fix this problem. Thanks.
