    Too many cooks . . .

    In the first place, one is enough. Secondly, some AV progs will not function with another installed.

    Suites like Kaspersky, and the free version of Comodo, are more than adequate.

    Be careful about what is scared out of you

    Forum rules strive to create what is, to me, a professional environment. I know one person's food is another's poison and the gamut of 21st century mores embraces an infinite set. Mine is not a critique: I am not the judge - but I would urge a restricted use of colorful metaphors.

    The free version of Comodo Internet Security is a suite of AV/firewall/antimalware modules. If you refer to http://forums.mydigitallife.net/threads/4058 you will note some observations regarding many AV progs. It is my observation that most AV progs/suites adequately protect the average stand-alone system; they certainly have for me.

    When you install multiple progs that, at once, attempt to do the same thing, especially in the realm of shared files, something has to give since the OS is not going to be able to process what may be simultaneous conflicting requests.

    Thus, if you want to test Comodo, you must uninstall (not simply disable - although that might work in some instances) any other AV progs. Firewalls, however, are a bit more forgiving and you may be able to run MS firewall, ZA, etc., while running Comodo. However, Comodo "learns" what to do by observing what is being done; the presence of another firewall could be confusing.

    One final note: Comodo, for me, had a high learning curve. There are many options within modules and, although Comodo's context sensitive help is very useful, understanding what is being done and how to respond to different alerts can be daunting. If you are used to ZA, e.g., Comodo will leave you scratching your head. Just one example: install a complex prog that adds/changes thousands of registry entries (Office 2007). Unless you set Comodo to a so-called install mode, it will ask you to approve each change individually!

    Give it a try. As you noted, it is better than many and one source rates it better than Kaspersky - the current AV darling.

    Who me? Ah shucks . . . .

    Thanks Azrul.

    Actually, I am a retired healthcare administrator. I now write (fiction, non-fiction articles, training/white papers, blogs). Keeps me off the streets where I tend to get into too much mischief (read as: sucker for a pretty face). :cool:

    Curious

    1. Why subject oneself to redundant scanning?

    2. And, if redundant scanning does, indeed, yield a higher percentage of hits, when is enough scanning enough?

    3. Is there any guarantee that if I scan, say, 20 times with different AV engines/definitions that I cannot become infected? Still possible?

    4. OK, how about if I scan 50 times?

    5. And, if one is constantly attacked, is one practicing safe surfing?

    6. And who has or wants to take the time to scan redundantly?

    7. And am I content with all of these scanning processes eating all of my RAM and rendering my machine a coffee-cup holder?

    I know, I will employ one AV prog that is reputed to afford reliable protection and use the hours I saved for more fruitful endeavors - like offering intelligible solutions to pragmatic issues.

    Hi azrul...
    First of i don't think its possible. When install second anti virus, it shows you that anti virus already exist , you have to remove it and after that restart computer than you able to install new anti virus...

    You can install more than one antivirus the same as you can install another firewall program but it is not good practice they will clash:(
