Best of the Free Anti-virus Choices?

iamjoltman writes "I've been looking to replace the McAfee anti-virus on my parent's XP machine. So, I've been looking at the three free anti-virus choices, AVG Free Edition, avast! Home Edition and AntiVir Personal Edition. I know there are other options, but I believe any others are only on-demand scanners, and that's not an option. So, what does the Slashdot crowd think is the best of these choices? Keep in mind, I'm only looking in anti-virus, I'll go elsewhere for firewall or malware protection."

AVG here..

[the_rajah]

I've been using the free (as in gratis) version of AVG on all the Windows computers in the family for a long time and have been very pleased with the results.. No successful virus attacks in 9 computers over a period of at least 3 years. The hard part, and this is not specific to AVG, is getting the family members who still use dialup to stay current with updates since some of the downloads take quite a while.

I can't comment on the other free antivirus programs as I've not tried them.

Re:AVG here..

[twilightzero]

I'll third this comment also. I use AVG Free at home, my parents use it on their computers, my siblings use it (at my insistence), and the church I run IT for uses AVG Network edition.

The client is very light and non-intrusive as opposed to some well known others *COUGHNORTONCOUGHSYMANTECCOUGH*. I actually like that every email, both incoming and outgoing, gets a stamp that it was scanned. Lets me know that yes, it's still working properly and lets everybody else know that the email was definitively scanned.

The corporate network edition we use at the church is definitely VERY nice to work with. For $250 we got 10 licenses, 2 years of updates, and a central administration program. Installation is the easiest I've ever done on any networked antivirus:

1) Turn on all machines
2) Install AVG network admin tool on your file server (or any other machine)
3) Click Services > Install Antivirus, put in the relevant info, click Scan Network, and it will find all the active computers on your subnet.
4) Select the workstations you want done and click Install.

It's that simple. I think I installed all 8 workstations in under 5 minutes (and that includes turning them on and waiting for them to boot). You can also very easily set the server admin to download updates and push them out to the clients however often you want so the clients aren't bogging your network down with update requests.

I haven't used Avast but I've heard both good and bad things about it from other people, but I have yet to hear true negative feedback about AVG (true as opposed to fanboy whining).

AV Comparison

[OneFix at Work]

I would say according to this comparison, AntiVir is the best...and of course, this is the only comparison that really matters...

Re:Oblig: ClamAV

[jawtheshark]

I think you missed: I believe any others are only on-demand scanners

ClamAV is an on-demand scanner. Do not despair: with WinPooch, you can make it a resident scanner. Alas, I only read about it here on slashdot and didn't try it myself. Anyone here knows how good it is?

I personally use AVG Free Edition and it works just fine. It's non-intrusive and does its work well. That's the reason why I didn't uninstall it to try out WinPooch.

Avast vs AVG

[Alien54]

Avast has an excellent feature that nobody else has, which is the ability to scan in command line mode on reboot before major services load, similar to running chkdsk. This enables you to kill a lot of things that fire up as a wndows service. They get a gold star for this.

AVAST also has plugins for about a dozen IM and p2p services. This is excellent for a number of reasons.

On the other hand, the free version does not seem to have a scheduled scan feature, not that I've noticed.

AVG is more user friendly, does have a scheduled scan feature that Avast does not seem to have. It does not seem to have a plugin for IM and p2p networks.

Go with Antivir

[Deathlizard]

A while back, I did some testing of my own using the three above scanners. The test was done using a virtual PC VM that could be rolled back and reset, that way all three were tested with an exact PC image and system. Then they were subjected to an IE attack from a known malicious site (which I wont mention since I don't want you infecting your PC)

AVG was dead last, and could not stop even simple web attacks from propagating, even with the highest settings, although it was the least intrusive and fastest of the three, and didn't nag you to upgrade or anything.

Second was Avast. it stopped a lot of the malicious code, but some still got through and started to drop spyware into the system. It supposedly has guards similar to Windows defender, but didn't seem to do anything to stop the unknown propagations from occurring even on maximum settings.

Antivir was the best out of the three, catching most of the viruses at it's default setting, and all of the malware at it's maximum (it has definitions for questionable programs like VNC, Jokes and the like, but it's turned off by default) It's biggest problem is that it is the naggiest AV of the three, which constantly asking you to upgrade to the paid version. It also has a tendency to be very sensitive to programs that do virus like behavior at maximum settings, so expect some false positives from time to time.

PCMag Did This Review

[lseltzer]

PCMag looked at these three last September.

Most new computers come bundled with a free antivirus solution, but sooner or later you have to start paying to get the latest virus-definition updates. When the subscription lapses, your protection evaporates. Don't let that happen! If you don't have the funds or inclination to maintain a subscription, try a free antivirus utility. We looked at three that provide full system scanning and also scan all files on access. (Two others, BitDefender 8 Free Edition and ClamWin Free Antivirus 0.86.2, were omitted, because they lack real-time scanning.)

Re:Oblig: ClamAV

[i621148]

after you install clamwin:

open notepad and paste the below,

# Save this as C:\Program Files\ClamWin\bin\freshclam.conf
DatabaseMirror database.clamav.net
MaxAttempts 3
then do as the first line suggests and save it in the location.

then open notepad and paste the below,
echo off
cls
echo Clam Scan Open Source Virus Detection and Removal Script
chkdsk /f /r
cd C:\Program Files\ClamWin\bin
freshclam --datadir="C:\Documents and Settings\All Users\.clamwin\db" --config-file="C:\Program Files\ClamWin\bin\freshclam.conf"
clamscan --database="C:\Documents and Settings\All Users\.clamwin\db" --recursive --verbose --bell --remove C:\
echo .
echo beginning hard drive maintennance...
defrag c: -v
shutdown -r

save this as tune_up.bat somewhere and click on it when you
are done with your work everyday.

Re:RTFSummary

[erktrek]

You can use WinPooch in combination with ClamWin to allow for active scanning type goodness.

"As every 'real time' protection anti virus scanner I've ever reccommended has been more trouble then its worth (high resource usage, memory leaks & false alarm pop-ups causing the user to turn it off every single time), I would still go with my reccommendation."

For Windows, I've been happily using NOD32. The install file is about 11 meg, the install dir is about 25, and the memory footprint I'm seeing right now is about 16 (and I think I could get it lower by turning off some options). I haven't noticed any delay in booting and I haven't received any false positives. (It's even found things on my system that Norton didn't.) Best of all, the only two times I've ever received a popup were when it actually found a virus/trojan -- and you can even turn that off and have it act on its own.

The downside, though, is that I don't think it's grandma-friendly; options galore.

They have a free 30 day trial version if you're game. // That's my product placement for the day.
