Recently i have been having severe problems with my computer. I have logged on then it would freeze, taking 3 days to successfully log on due to the freezing and lag. I recieved a pop up for winfixer, but it wasnt only a pop-up but i got a message that said "Windows detects problems with your computer, whether it be crashing, freezing, or acting slow. Would you like to download Winfixer 2005 for free?" Something like that. Well i usually dont trust pop-ups, but i think winfixer is official is it not? Should i download or could it be carrying a virus? Thanks for your help.
