    Can I run more than one anti-virus product on my computer?

    I had problems with my anti-virus software and now don't know if it is working or not. Can I install a second, 'back-up' anti-virus programme?

    No. Antivirus programs all have their own virus definitions, firewall bypasses and functional operations. Since no antivirus programs operate in the same way, running two at once will cause major performance issues, can cause more harm than good and can even damage your important Windows files.

    No.  Antivirus programs hook themselves to the very innards of your computer's operating system.  If you run 2 or more of them, you may find your computer freezing, locking up, or running extremely slow.  One of the very basic things anti virus programs do is to scan every executable programs being opened.  If two of them are trying to do this,  it's possible they can get into a gridlock situation.  When they do, your computer will lock up or freeze.

    Even anti virus vendors don't recommend installing more than one.

    However, you can install other tools that compliment your antivirus program, like a malware scanner, or a registry cleaner.  Those type of tools check other vector of attacks in ways that won't interfere with antivirus programs.

    I think the answer is you could, but you should not because you will face a bunch of problems. Now, you can run an anti-spyware utility in conjunction with an anti-virus program. I use to do that on the computers in the office where I work. But, it has to be a good anti-spyware program and you may have to disable to virus software--not always.

    The problem with anti-virus software is the companies do not know when to stop. I used Norton for years, but it turned into bloatware. I have been using AVG for about four years and the latest edition is bloated.

    I do agree with those that say you cannot run two anti-virus programs at the same time. However, the spyware is sometimes more dangerous than the viruses and do not always get immediate attention by the anti-virus vendors.
