Performance computer and software security

I've seen a lot of comments on computers with Windows 7, hampered by the host process for Windows Services, the Antimalware Service executable and other security products. Is there a straight answer about whether it is possible to stop these programs make the computer unusable almost several times a day? Other, that is, the switch to a MAC system?

Because an AV program must analyze any file being loaded on the system or written to the disk, it must have an impact on performance, when these programs are discussed in the computer press is one of the factors considered by the examiner.

It is a continuous process and can't seem to ' several times per day ", they can do a scan scheduled on a regular basis, but the regularity and time actually chose to do can often be defined by the user.

If there is a problem of my own experience it goes often to the excessively feature rich security 'suites' preloaded by manufacturers of computers and sold as commodities in a box computer retailers. It is hard to tell if it's actually the scanner AV itself or those extras in the package is the root of the problem, but I've lost count of time remove these packages have a massive impact on the return, resettlement in most cases do not reintroduce problems so I guess that all the cleaning has had an impact.

It would be good to have more choices, but the main reason why I tend to prefer Microsoft Security Essentials/Windows Defender is its simplicity. It has not all the peripheral functions and so far I've seen few tend to develop these performance issues.

Don't make the mistake of assuming the Macs are immune, they still need AV protection and my iMac just completed an update which includes security fixes.

  • If I send telemetry information, is there a threat to my computer and personal security opportunities?

    I read the info provided and understand the details of my use of the computer and the I.P. address are collected for experimental and statistical data. Are there chances of my data compromised as it is sent, or after it is received? I'm sure most people would have their question answered by the information provided. Normally, you offer the only instructions I can understand. I apologize for my lack of knowledge.

    However, I trust Mozilla/Firefox and despise this ' other browser' and their attempt to email. I used it only temporarily because I need to download my email Juno and thought they were the only ones that offered this option.

    Laughing out loud... I need a complete encyclopedia "all for computers: your PC, Firefox, Email, Windows, words of understanding, etc.". Until a person educated me yesterday, I planned to spend my email in Thunderbird, just because it is your product - but it does not include an e-mail account.

    In addition, I'm going to try to create a new account of Firefox and upgrade to the new sync... I copied everything, but if you have any advice or information to help me not mess up... Please let me know.

    Hello

    To add the good advice of TG, you don't want two of the main antivirus on the computer products
    at the same time much less running. Don't forget to use the removal of the machine tools to prevent
    problem causing leftovers when you want to uninstall/remove an antivirus/security products.

    reliable and compatible. Use MSE or Avast and Prevx, Prevx 3 but not all.

    Avast Home free - stop any shields is not necessary except leaving Standard, Web, and

    Also get Malwarebytes - free - use as scanner only. If you ever think malware and that
    would be unusual with Avast and occasional Prevx running with the exception of a low level cookie

  • I cannot perform certain functions because he says that I'm not an administrator, but it's my computer and I'm the only one who uses this computer__

    I cannot perform certain functions because he says that I'm not an administrator, but it's my computer and I'm the only person who uses this computer

    What are the functions? More global changes (changes to the system, software installation) require an elevation in Vista/Windows 7.

    Changes to the built-in Vista administrator account

    http://support.Microsoft.com/default.aspx?kbid=942956

    User - recommended configuration (Vista and Win7) accounts

    You absolutely don't want to have only one user account. As XP and all other Windows 7, Vista, and modern operating systems are operating systems multi-user with integrated system of accounts as default Administrator and comments. These accounts should be left alone because they are part of the structure of the operating system.

    In particular, you do not want account only one user with administrator privileges on Vista and Windows 7 because the administrator account integrated (normally only used in emergencies) is disabled by default. If you use as an administrator for your daily work, and this account is corrupt, things will be difficult. It is not impossible to activate the built-in administrator to rescue things, but it may require more work you want to do. Better not to get into a bad situation at first.

    The user account that is for your daily work must be a Standard user, with the extra administrative user (call it something like 'CompAdmin' or 'Tech' or similar) only it for elevation purposes. As a user Standard is recommended for security reasons and will help protect your computer against infections. After you have created "CompAdmin", connect to it and change your normal user account Standard. Then log on to your regular account.

    If you want to go directly to the desktop and ignore the Welcome screen with the icons of the user accounts, you can do this:

    Start Orb > Search box > type: netplwiz [Enter]
    Click continue (or provide an administrator password) when you are prompted by UAC

    Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null). MS - MVP - Elephant Boy computers - don't panic!

  • is to have sufficient protection so much as my one and only security software Microsoft Security Essentials

    l download Microsoft Security Essentials for my windows 7 but later unintentionally downloaded McAfee Security scan plus.

    is there a conflict? should I just uninstall it, therefore less heavy for my pc?
    Thanks in advance

    Don't know why this link does not work... McAfee must have fired or their FAQ is under review.

    The Development should work... and you can uninstall/remove the application after that you are through using it.

    Here are a few suggestions of Stephen Boots, moderator of the MSE Forum about fake antivirus programs and prevention measures General malware:

    Unfortunately, this type of malware attacks are difficult to follow because they fool you by letting them install. They usually come to an infected web site and usually an advertisement. You get a pop up of infection and click on it to close the window pop up that allows you to install infection.  They can also be provided in a "drive-by" mode without any action required by the user due to the system being unpatched, any security software is running.

    When you encounter one of these fake virus pop - up during navigation, immediately do the following:

    -Do not touch any window of browser to close or navigate away.
    -Immediately, press Ctrl-Shift-Esc and bring up the Task Manager and end by force all instances of iexplore.exe, if you use Internet Explorer, or the executable for the browser you are using.
    -or-
    -Go to start/stop and reboot the PC without touching the browser windows.
    -If you used the Task Manager to close the browser instances, restart the machine.
    -Then go in the Internet/Panel control Options and delete all temporary Internet files and cookies. If you use another browser, open the browser settings to do the same - to delete the local cached files and cookies.
    -Perform a full scan with your anti-malware program.

    The steps above should prevent infection taking root.

    In addition to using an anti-malware program, the following recommendations will help to protect the PC from infection:

    S ' ensure that the Windows Firewall is enabled.

    S ' ensure that all critical updates or important, including service packs for the operating system and programs are installed from Microsoft Update (Windows Update).

    -Make sure that Internet Explorer is version 8 or higher and put up-to-date with all the patches.

    -In Internet Explorer 8 or 9, use the SmartScreen filter.

    -Make sure that the Internet IE security settings are at least put to fire medium-high (default).

    -Turn on the pop-up blocker in Internet Explorer.

    -On Vista and Windows 7 make sure that thatUser Account Control (UAC) and doesn't work with elevated privileges.

    -Make sure that automatic updates of Windows are set to notify at least, but the preferred setting is to download and install automatically. If you update manually, be sure to update as soon as possible after being informed of updates available.

    -Make sure that installed applications, including Adobe Acrobat, Adobe Flash and Java are at their latest versions. Many vendors are regularly updated and fixes security vulnerabilities.

    -Never click through links from unknown sources and be careful, even if they are from a "reliable".

    -Do not open attachments in unsolicited e-mail.

    Good luck...
