My PC is running Windows 7 Home Premium (32-bit), and has avast! Free Antivirus v5.0.545 installed. The latter works efficiently and satisfactorily.
Is it appropriate to have a cloud antivirus, like Immunet Protect v2.0 or PCTools ThreatFire v4.7.0.17, working side by side with avast! Free Antivirus. Significantly, a cloud antivirus does not rely on signatures to update. Ideally, this may enhance avast! Free Antivirus with another layer of protection.
Any user’s views?

Its never good to have 2 anti-virus programs running along
side of one another…can cause major conflicts
Hi A. Chung and welcome to the forum. Everyone will have their own opinion, but I do believe in having layered protection. If you start looking at people’s signatures in this forum, you will see some of the layering I am referring to.
Regarding a cloud AV, I use PrevX w/SafeOnline with no conflict with avast (make them both trusted exclusions). Additionally, you can also give yourself protection with on-demand scanners like MBAM or SAS, just to mention a few that most of us use. You can also use some handy add-on’s offered within your browser to exclude scripting, LSO’s, adware, etc.
I might suggest doing a search on this forum re: immunet to see some feedback others have had with the combination of the two software.
I hope this helps, and welcome again. 
Hi, hayc59 and SafeSurf
Thank you for your prompt response.
I understand that it is not advisable to run 2 antivirus programs at the same time. As highlighted by the publishers, both Immunet Protect and PCTools ThreatFire (freeware) are able to run side by side with an existing antivirus software, thus causing no conflict.
Actually, I do carry out on-demand scanning with MBAM and SAS. As mentioned, I guess Prevx with SafeOnline is a paid version.
The cloud antivirus is just a matter of curiosity.
Once again, thanks for your expert advice.

A. Chung
You are correct in your research mentioned above, and you are quite welcome. Feel free to come back and visit us again. 
An alternativ is Hitman Pro 3 - Second Opinion Malware Scanner http://www.surfright.nl/en/hitmanpro
ThreatFire isn’t cloud AV, it’s behavior blocker… and it’s possible to run it with any other AV.
Immunet Protect is really Cloud AV and it’s also possible to run it with any other AV.
I think will be good avast! also develope cloud based technology…
tsilo, I agree and hope Avast is thinking, Cloud-Tech. I would hate to see Avast left behind and people saying “Avast use to be good” like is the case with AVG and Spybot…
For what? To stole the other antivirus technology? To promise more than you can deliver?
Cloud technology seems to be the beautiful girl of the antivirus world ;D
I have a strong hunch, that Cloud-Tech is the future of computing, so either jump on board or be left behind. JMO
the problem with the cloud based technology is:
If a Malware cuts your Internet connection your AV is gone!!
I trust more in a Local Database of signatures IMHO… ;D
Light Archangel, that is not completely true with adding some Cloud-Tech, but I will let you research the truth for yourself…Computing is still in it’s “extremely” early infant stage and has a long, long way to go. Cloud-Tech today is far from being where it will be down the road aways, so it’s mainly a concept or idea being newly developed and before long, some young new geek’s will come along to really kick it in and get it going…Again, JMO
If a Malware cuts your Internet connection your AV is gone!!Most malware need internet connection to do the work it was designed for ......
It’ not true, they work without Internet connection too…
Because not to be far from future…
avast! has anti-routkit, has BB, has heuristic… and you think it was alwil team who first developed such technologies in their product? or you think they stoled from other AV companies these ideas?
I know what I’m talking about. I’m just talking about upload files from user and testing it against the antivirus.
Don’t trust me? Trust Vlk

I know they work with a local caché but this isn’t enough to make a deep analysis :
Well, is decision of the developers include cloud tech in their products…
I think Tech’s intention was to close this thread with those links from VlK, if I’m not mistaken…
No. It’s not my intention to close anything. I do not have this power or want it. It’s just my opinion and Vlk’s one.
Tech, “I sit corrected” than, it’s all good…
