I am now in safe mode. After I follow steps 1-4, in step 5 it says: "5. Download an automatic removal tool from this page and run a full system scan. Or download it form alternative location." So, I clicked the "Download remover for AV Security Suite", and then it says: "Before you download: run a free scan for Windows error", and tehn when I clicked that it asks me to run "registry". Should I click that? Btw, I am so sorry for typing slowly, and whether it disturbs you?? I mean, it porbably will take long.. as it is now 4:40 AM, I will sleep in half an hour, becasue I have to go to uni tmorrow (I mean today), but I will check back this thread in the afternoon, in case you also have to do other activities. Thanks a lot for your help! So I click "registry", yes...?
