Replying to Antivirus Slows Down Your PC?

Norton Anti-Virus 2011 slowed my computer down to crawl. like a 286 computer!Antivirus Slows Down Your PC?

After installing Norton 2011 Anti Virus. My whole system slowed down to a crawl and got slower each day. What a bunch of crap Norton is. It used to be the best. I will not **** with it again. Stick to Microsoft anti virus that comes with XP and shareware free. I just lost 50 clams faster than placing that money on a 3 legged horse, blind and a 300 lb. Rider!.

I have used many antivirus programs in the past mainly due to the fact that they slowed down my computer to such a slow pace that I ended up getting annoyed and uninstalling them

I am currently into freeware antivirus software and highly recommend avg and avast both of these seem to do the job just as well as the commercial pieces of software such as Symantec/Norton antivirus and McAfee. I have noticed that the avg and avast anti virus programs don't really seem to slow down your machine unless they are performing a full scan.

I have used Norton/McAfee in the past and both pieces of software have, on numerous occasions, caused by computer to completely slow down and crash. I have used the internet security suites of both of these too and these were particularly bad, worse than just having the antivirus program on its own.

I used McAfee Antivirus and Norton Antivirus and I agree with you that both of them slow down your computer because they take up too much RAM. In my opinion, I believe that it if you have a large amount of RAM, you will not see much of a noticeable difference in the drop of speed. If you have only one or two gigabytes of RAM, then you may want to try Panda Cloud antivirus like I use since it is very lightweight but still does its job.

A bus spotter friend of mine has Kaspersky installed & has found that he is blocked out of a well established bus web site. The reason its been identified as a phishing site. Which is total crap

McAfeeAntivirus Slows Down Your PC?

I don't know what crap people are saying about McAfee,But my opinion is that it is a resource HOG.I am a gamer and I play strategy games that have many units on the screen.When I had McAfee on my system it caused extreme game lag.So since I was not using the net to play my games I decided to turn off all the settings in McAfee.Even when you turn them off  it still has background programs running.I used Game Booster which turns off all programs not needed to play a game and it still could not shut down McAfee back ground programs (scanner auto updates and warning popups).I went to my registry services to shut anything down that McAfee had running and found 3 that would not allow you to sut down.

Even with as much as I was allowed to sut down on McAfee I got the game lag.I also got video stutter and lag when I tried to watch online tv and movies.

I have a fast overclocked system and should not be hindered by a program.

780i MB

8gig 1066 ddr2 ram

Pentium e8600 dual core processor

2x GTX285 FTW video cards in SLI

So I uninstalled McAfee and my system is screaming again.Games are running very smooth.Video and Movies have no stutters or hicups.

My opinion McAfee sucks.

Kaspersky problemAntivirus Slows Down Your PC?

I got infected with some trojans and viruses. I needed a more powerful anti-virus than norton. I installed a trial version of kaspersky 2010. I decided then to disable is as my computer was working very slowly. Before disabling I got a message, something like: "network connections shall be disabled. Yes/no". I chose "yes" by mistake and there it is my problem. I cannot have access to the other PCs I am connected to. Strange thing is that I am connected to the internet and the printer and I can receive e-mails but I cannot send. I uninstalled KAV but no improvement. I am desperate, I no longer have access to PCs I am connected to. 

Can anyone come up with an idea? Thanks.

Kaspersky is slowing your computer for about 60% according to me. BitDefender is slowing about 75%, NOD32 it's the best antivirus but with weak firewall. Because of that i decided to make my combination and here it is: Outpost Firewall Pro 2009 + NOD32 = Deadly combianation. Try it, it's slows the PC about 35% according to me Im using it and i am happy with big protection and small system requriments.

norton slows down the most. the lightest tested by me is avira antivir.

One antivirus that doesnt slow it down....Antivirus Slows Down Your PC?

I've used Norton and McAfee before, they both slow down my PCs, and they're pretty powerful PCs. Norton is HORRIBLE about slowing down computers. Almost everyone who has ever used Norton knows that. But Live OneCare from Microsoft does it all and doesn't slow down computers. At least not mine. And theres the price. For like 50 or 60 bucks, you get protection for 3...Yes THREE computers for about the same price as ONE Norton or McAfee license. REALLY useful for people like me who have more than one computer. Plus, if you install OneCare on a network (like a home network), and one computer installs a printer, OneCare will detect the printer has been installed on that PC on the network and will ask you if you want to install it on the computer, don't even need to go get the disks. It does it all for you. Very useful. It also does automatic backup of all the PCs that OneCare is on. Say you have it on 3 computers on your home network...And you want to back them all up. You can have all of the computers back up to an external drive on one of the computers automatically. Like that cheesy old infomercial use to say "Set it...AND FORGET IT!! (applause)" That, plus I've used the other two products, and they've NEVER cought a virus as I got it. I've seen Live OneCare catch SEVERAL viruses (mainly from Limewire, don't just me). Norton and McAfee only detected stuff once a scan was ran. I usually have OneCare closed and only running in the background, and still it catches viruses as I get them in real time. I HIGHLY recommend Microsoft Live OneCare.Replying to rapco

That's a fact. I think every antivirus does slows your computer down because it needs resources to function and to check the system. I think every antivirus I used slowed down my computer but the one slowed the most was Nod32.
