do anti-virus programs slow your pc down?

Yeah i true i had faced it as well but its better than to loose data

Anti-virus programs do consume system resources but if you have an upgraded pc then you will not feel anything.If you have an oudated pc then you will notice your system slowing down because of the scanning that your antivirus tool is performing in the background.You can try light antivirus tools that consume leeser system resources.There are various on the internet and they are free as well.

If you have a slow or low specification computer that you might feel that it is a little bit slower and a lot slower when the anti virus program run its daily scheduled check up on your computer. Otherwise, you can't really see any difference.

According to all the research I've read, they say that some of the anti-virus programs do slow it down, but not all of them! And I do recommend the anti-virus program, because I have already lost one computer due to not having one! You can research or ask around which one would be good for your computer!

Yes, Antivirus programs do slow down your pc. But if you compare the use of the program to the amount of slow down, the use is far greater. Without the antivirus you might not have a system to slow down in a few days, right?. Safety first :). If you're still worried about your pc slowing down then you can use Kaspersky internet security, has got some great reviews and some of them have run benchmarks and said that this program has the least computer response delay.

Anti-virus only slow down your computer when one of two things occur. Either the software is of Norton brand, or your computer does not have a HT process, or DUO/QUAD processor. The reason why an anti-virus software does slow down your computer is because it is constantly running background task. The task eat up your memory, and or processor speed, thus causing you to have reduced performance. You might notice that some games ask you to make sure you have your anti-virus software disabled before running their game. This is for increased performance. If you have a HT, DUO, or QUAD processor, it is almost like having 2 or 4 processors running together at once. This allows you not to have strain on just one processor- thus, not causing your computer to have drag or reduced performance. The thing with Norton, is that it is incompatible with Windows, even though they sale their software with Windows. It is quite ironic actually. So, if you have a Norton Anti-virus software, or Kaspersky, it would be highly recommended that you un-install it, and switch to another brand. I hope this helped you out some =].

I doubt if anti-virus slows down our pcs, on the other hand a good and quality anti-virus programme helps our computer from infecting with various kinds of viruses.

It doesn't have to slow down your computer. When they are running you can just minimize it and you can continue to work. Everybody needs to have one on their computer or your computer would not be running for very long. The minute you enter the internet you could pick up a virus. And if you are reading emails for money, well, you could pick up a virus a minute. So even if your anti-virus program does slow down your computer it is worth it.

yes they do slowdown your computer,if it is not properly configured.because it is using resources from your memory then it uses up the memory that should be used by your programs,it is better to configure your antivirus program fir it to not use up so much memory that would make your computer slowdown.

anti-viruses do slow down your computer just like any other program. every program needs to use RAM space to run so in that sense it slows down your computer. AOL, Internet Explorer, Firefox, etc. all slow down ur computer...

The program I have dosn't seem to slow it down not that I notice atleast. But some programs may slow the computer down or it could be that the coputer needs to be cleaned up and defraged.

Of Course is makes our computer slow.. Im Using Kaspersky Antivirus 7.0 and i feel the slow.. Ever my RAM is 1GB --a But.. for the security and risk i prefer you too keep the antivirus installed ^^

All Anti-virus (in fact all programs) slows your computer down, i use Avast that gives a good protection against viruses, Trojans, etc and only slows your computer down a bit, so get Avast, it's a good program uses no cpu (almost), and gives good protection.

if it's Norton or McAfee yep it can slow you down ALOT

haaaa..... of course that proccess eat lot of cpu ram :P I don't need AV just trash in my computer hehe lol.

Hello dear glitzypurple. Everything has its two sides. When the anti-virus programs are slowing our pc down, which is a fact, it is also helping protect our computers. By the way, once I had it installed on my laptop, but as it slowed down my laptop, un-installed it because I want to have a faster speed. But I have to be careful not to open suspicious sites. Thanks for your discussion.
