I have Microsoft Security Essentials on my Windows 7 computer and I get this “Windows Security Alert” from Cleanerworrysaferyin saying it detected Trojans and ready to remove them. They want to put up a setup.zip. I was watching Netflix and my computer stop dead in its tracks and this warning came on which it has done several times and I run a scan and everything is clean. I think this is some kind of advertisement which just stops my computer in its tracks? Also last night I get a call from Skype saying my computer is at risk. All this crap is invading my privacy and I have “Microsoft Security Essentials” but I don’t think it’s enough so can anyone give me some advice on how to stop all this crap. Thanks. PS: What is this 7-ZIP 4.2? Is this something I should be downloading?
