Default UnThreat Antivirus Free

UnThreat is relatively new in the field of free antivirus. Its available here :

http://www.unthreat.com/free-antivirus

Saw it mentioned on Wilders, and also, its RAP quadrant result on VirusBtn looked good.. so decided to try it out. Have been using it on my PC since a few days. Will write my experience, which is mixed, of sort.

The interface is clean, and quite pleasant.

The settings are also neatly laid out, and organized, which is really good.

Under Active Protection though, the setting for "Check files when they are copied or opened(on-access)" is unchecked by default, which I found strange. It should have been checked. So, users who install UnThreat AV should check that option first thing, if they want it.

Also, the setting for action on bad programs detected by default is "Block and sent to quarantine", which maybe good for general users... but the more experienced users might want to check the other option, which allows them control over the action to be taken.

Although in the settings, the option for show notifications has been checked, but I personally never saw any update notification, or any other notification. Maybe they are referring to the info that appears when you hover mouse over the tray icon? Can't say.

If I go by that info, and the time and date shown there, then the AV seems to be updated regularly. However, lack of notification, and also lack of info about the time and date of the last update, elsewhere in the program interface, makes me feel a bit uncomfortable.

Also, it performed a major update of around 75-80 MB, two days after I had installed it. That also seemed a bit strange to me. Why this much big update, after two days of installation? Don't know if it was updating the definitions, or the program itself. It would be good, if they gave some info to clear all this up.

The AV uses quite less memory, and appears to be light. That's the good part of it.

The bad part is that, when the AV gets into action, like, on opening folders containing many exes, or accessing files... it tends to use CPU a lot. The delay when opening a folder full of exes, is quite a lot, and can be irritating sometimes. Also, while that happens, the other operations become slow too... the system becomes slow.. the browser sometimes does not respond for a few seconds.. etc. This is something that they need to improve on. Earlier to the major update that I got, it was really really slow... but, after the update, things seem a little bit improved. Still, it is really on the slow side.

Also, its random at times. Sometimes, if you open a folder, it will show the files at lighting fast speed.. happens only occasionally. But, other times, the delay can be quite a lot.

Also, I observed some quirky behavior in the last two days. Yesterday, suddenly, I could not see the tray icon. It just disappeared ! I tried to run the AV manually from Start menu, but it didn't appear. I had to restart the PC.

Today too, when I booted the PC, there was no tray icon, and tray seemed strange. After a restart, it was back to normal.

So, overall, I think that the AV has potential to be a great alternative, if they improve on CPU usage, and the delay occurring in file/folder access. Maybe that's why they have kept the on-access setting off by default

And I hope they keep improving that detection rate.

I noted that in the latest VirusBtn RAP quadrant results, UnThreat is not there.

Help file>Trouble shooting>Performance issues:

If the performance is affected when you are scanning your system with UnThreat AntiVirus, try closing all applications. The less you have open at the time of the scan will aid with possible memory issues.

Change the Scan Speed and Scan Priority in the settings of UnThreat AntiVirus to Low priority. See Scan Settings

Have you tried adjusting the aforementioned?

Thanks... but what I wrote was not regarding scan.. I haven't mentioned scanning anywhere in my post. I was talking about the delay which occurs when a folder full of exe files is opened... it takes time for the icons to be built. That delay is quite long.

Avira and Avast too have such delays, but their time period is quite small. Avira has less, and Avast slightly more. But, in case of UnThreat, its quite a lot, and it affects system performance at that time.

I've been running UnThreat now for some time. Admittedly I'm using Linux for most of the time but still I've spent quite a while in Windows. I too have seen this behaviour which is common with all antivirus programs. The degree of "lag" is affected by external issues too such as system type, firewall, other security software and the relative power of the computer. I found UnThreat to be worse than some, but better than others such as AdAware. I also found that opening the same folder a second time resulted in less lag than before. Ultimately, I don't think losing a few seconds to a program that is doing its job is that important, but if speed is a priority then security will always suffer.

A few seconds really don't matter, but if it starts to take really long, and you have to wait for the process to be over... or, if other operations start to get affected, and the system gets slow, then its a problem.. and with UnThreat, it can be like that.

It works surprisingly well on-demand. There is a background service though.

Out of interest, I'm in direct contact with these guys who are highly responsive to any issues.

Some might have noticed that UnThreat was recently featured in the VB RAP tests (with excellent results) and then disappeared. They will be back there again as soon as the updated Vipre engine has been integrated, and there are also plans to place UnThreat with other independent testers too.

I have to say that UnThreat has been the most trouble free AV installation to date on my machine.

Thanks for the update MC.

As written in my first post, I was wondering where UnThreat disappeared from the latest RAP results.

It would also be good to see UnThreat being evaluated in some independent tests.

The AV certainly has potential.

Using UT as a backup on demand scanner for a few weeks now. Quick scans r blazing fast (even when low resources are allowed). Full scan is a bit on the slower side IMO.
using with Avast and online armor free on Win7 sp1 32bit. No problem so far.
[Missed a trojan.Vundo yesterday though,but Avast and Kapersky's rescue cd(USB) took care of it.]

This may be off topic (sry!) can anyone tell me how is bufferzone pro(freeware)? I see a Black screen after installation and restart.
