Can someone tell me which is the best, most lightweight anti-virus with the fastest scanning times.

The anti-virus must be lightweight and quite good overall but as I have been a PC user for a while and know which websites to go on and which ones could be harmful then it does not have to be the best.

Please give me some anti-virus choices with the information that I have left you as I am in need of a good, lightweight anti-virus that has frequent virus definition updates.

Also, please tell me which anti-virus you use and which operating system and web browser you use along with it.

Thank you. Your answers will be appreciated. (Do not close this question if someone asked it before, the search isnt working and also many anti-virus programs could have been updated since the last

@TheTechDude both of those questions are asking something different, please don't make blind attempts at moderation

"Best Anti-Virus that doesn't affect resources"...That sounds a lot like "the most lightweight". And best for not slowing things down. They both are asking the same. Maybe you should read what I post as duplicates before you comment. If this was a blind attempt at moderation then I would have closed the question. The asker had a good point as to the fact that there could be new anti-viruses out. I post the links to the closey related to duplicate questions and then leave it for someone else to decide wether or not it should be closed.

Microsoft Security Essentials it a very lightweight and also free program. Avast is a good one a bit better than Microsoft Security Essentials but not as lightweight.

I use Kaspersky Internet Security 2011, along with Google Chrome and I run Windows 7 Ultimate 64-Bit. Kaspersky is a paid and not cheap Anti-Virus and is also not as light on resources as the previous 2 but it is better than them.

My recommendation is Microsoft Security Essentials.

Do you know much about MSE?

Ive never used it before but does it update regularly?

(Dec 23 '10 at 19:03) Liam Liam's gravatar image

I would not recommended something unless I knew about it. It doesn't update as often as some anti-virus programs but it doesn't need to. I think that it updates daily. Why are you looking for something that updates a lot?

(Dec 23 '10 at 21:13) TheTechDude TheTechDude's gravatar image

I agree, MSE is a good anti virus prog. I don't see the sense in updating it more than once a day. It does a fairly good job on doing what it's designed to do. It hasn't interfered with my day to day running of my PC. I've used it since it went public and found it very good. It also is integrated with Windows Update, so you'll know when to install the latest version and any updates that are available.

I run Win7 Home Prem 32bit, using both Chrome and I.E, but mostly Chrome.

Merry Christmas Everyone

Thanks for all the answers guys, merry christmas to you all!

I wish Avast was free...

They have a free version.

AVG is awful, it recently detected Google Chrome as a Trojan. Wouldn't recommend it at all, to me it just seems too complex and is quite heavy on resources.

I use Avast which I find to be quite good. It is very lightweight and I hardly notice it when it's in the background doing nothing. The scans seem to be quite fast and the virus definitions are updated every day in fact it popped up as I'm typing this answer with the message "Virus database has been updated".

Have you tried Kaspersky? Its got very powerful filters that will protect your PC from trojans, worms, spyware, rootkits, keyloggers and many other viruses your PC may have. Try this free Kaspersky download here -

Removed Link, Spam, Illegal downloads are not allowed, it leads to a virus(stop doing that)

The truth will set you free.

Unless you specifically tell me exactly what you do on your computer, it sounds like you only use a web browser. I recommend Ubuntu, because you have such a little chance of getting a virus, that you'd be struck by lighting before then. Do you know the best part about Ubuntu? It doesn't hog up resources like Windows + a virus scanner. You might actually like Ubuntu, I know that I do.

I don't really want to change my OS, I do many things on my computer, Watching movies, video editing, picture editing, some gaming, and things like that.

(Dec 23 '10 at 18:28) Liam Liam's gravatar image

I have a tricky question for you: From where do you get viruses most often?

Hopefully if you will answer this question correctly you will understand what I'm saying!

LOL, Linux For Human Beings. . . what a joke. You still need to have some knowledge of computer technology to even get it up and running. Give me a call when it's as easy to use as Windows or Mac for my uneducated PC customers.

Did YOU even try the newest version of Ubuntu??? Don't seem so!

I found that Avast is actually more lightweight than MSE.

It sometimes is...I have s found that depending on the computer but more times than not it is the other way around. Glad you found one that is good for you.

MSE is Weak compared to Avast!... I will rather use Avast! with threat fire than MSE

(May 18 '11 at 06:58) Saakeman Saakeman's gravatar image

I, personally, use AVG Free and Malwarebytes. The only bad thing about Malwarebytes is that it doesn't run all the time, meaning it doesn't detect viruses as soon as they are on your PC.

AVG is a good piece of JUNK, especially the free one. I will use Avast rather than AVG, and I will still not be secured. COMODO for the win!

(May 18 '11 at 06:59) Saakeman Saakeman's gravatar image

Panda Cloud with threat fire for you... Or Comodo

I use Comodo internet security ~ The best AV (see why). Windows 7 (Secondary OS). Hitman PRO manual scanner
