I am trying to rescue a friend’s computer that is infected with malware. I usually use 360 Internet Security with no issues, I simply install it and let it do its work. In this case however, I cannot get past the installation. I am thinking that the malware is terminating the installation process every time.

Is there a solution that would allow me to install 360 Internet Security? Or should I try with another antivirus?

I have just bought the newest version of Bitdefender Total Security. I am very happy with the user interface, and it doesn’t seem difficult to use, but I have not yet been able to complete a full scan. I start the process normally, but then the program stops responding. There is nothing I can do, but reset my computer. I don’t even know if there are any viruses, because I never see the end of the process.

Am I doing something wrong? Should I be doing things differently than in previous versions?
