i got few nasty things on my pc and i need help.virus shut off my anti virus and dint let me install avg,wouldn't let me do a system restore,took me awhile to run house call cuz it kept closing the window,even shut off my pc few times im not even talking about spam and some software installs from nowhere. I've done all the steps in Viruses/Spy ware/Mal ware, preliminary removal instructions. AntiRootkit didn't find anything. I was also trying to install Nero 8 i currently have 7 and when i try to install 8 it tells me i need to uninstall 7 first, when i prompt if i want to delete old version i hit on yes it tells me that it cant find Nero.msi .i tried to search for it with windows search but it doesn't work i see the stupid dog but there is no search bubble on top? also few other softwares acted the same way.so i cant uninstalls them now? Thanks for your help, i don't know what would i do with out your help guys.
