  • IPhone 3GS Best Antivirus Program/Protection

    I heard a lot of rumors on how IOS does not really need an antivirus because the software application is quite sure just within himself. Even if I have OCD and I am always worried about something. That being said what is the best Antivirus Program (free) that I need to download for the safety of my Iphone 3GS. Even if I could not ever having a virus problem or whatever the cause. It is just a type of "peace of mind" of the thing im dealing with.

    It must also be free software because I have no money to invest in the purchase of a request right now.

    Please someone help me to find what I'm looking for.

    May God bless those who can help me understand my situation.

    Thanks again.

    There is NO antivirus program for iOS. Because iOS does not privilege any sufficient demand to see what is happening in the operating system or install apps. Your 3GS is safe. There is no need and that you can not use an antivirus.

    Hello

    One of your antivirus programs? You should not have two or more on the computer much
    less running. They load the pieces themselves at startup and interfere with each other
    which can actually reduce safety. If its best uninstall all but one and run the removal
    Tool or look for the special removal for these deleted instructions.

  • It is better to have two antivirus programs to be sure?

    original title: MS Security Essentials?

    I am now under Webroot Internet Security complete and I was wondering if I have or should run/download MS Security Essentials? I read somewhere that it is better to have two antivirus programs to be sure. What should I do?

    Hi Richard,

    Contrary to what OU a course, you must have a real-time protection anitmalware/antivirus program installed on your computer. Major reason being disputes between two to treat an infection. However, you can have other scanners on request, indeed since no antimalware/antivirus software is 100% sure I'd say at least one to increase daily or weekly scans with your resident security program.

    Microsoft Security Essentials offers protection in real time for your home or small business PC that protects against software viruses, spyware and other malicious software.

    If you Choose Microsoft Security Essentials cleaning/unistall this guarantee as well as programs of real-time protection previous using tools and methods remove properly.

    You should also consider how to use the Microsoft Safety Scanner(similar to MSE, but it is a self-contained/not installed scanner)http://www.microsoft.com/security/scanner/en-us/default.aspx

    Online scanners are also good second opinion option. My preference is ESET OnlineScanner.

    Another recommendation is free WinPatrol. Although not a software program anti malware/antivirus in the usual sense of the term, it monitors your computer and landlords of any changes to your system that could be associated with malware. It can be run in real time with other products without conflidt because it does not take immediate action on the issues.

    You will need to run the "fusion" in the context menu of a reg file, published as part of the solution to change some registry settings. On any folder, you'll get a context menu 'Take Ownership' which restores the property correctly. This solves a lot of problems installing.

    Many people have trouble with this and therefore decided to post here.
