on demand scanner

Hi,

I currently have installed:

nod32
comodo
avg anti-spyware

I do not have avg running but am trying to use it simply as an on demand spyware scanner for downloaded apps (ie the setup or zip files). I am fairly convinced that nod32 analyses the contents of the setup file but does avg work in the same way (when I right click the exe/zip file and choose scan) or is it really more for scanning your system once you have installed the software.

Is avg anti-spyware the best choice for this, are there any other suggestions - free or one off purchase pieces of software are preferable.

Thanks for your help and apologies if its a really noddy question

 

avg anti-spyware has a lot of false positives in my computer,especially detected

some packed programs as "Dropper.Agent",I recommend nod32.

 

For on-demand scanners I can think of two free programs that you may like:
A-Squared and SUPERAntispyware.
You are talking about explorer integration where the scanner is listed in a box after you right-click the file?
A-Squared free does that.

 

Hi, folks: You may or may not know that there is a DNA-type difference between Nod32 and AVG AS? One is firetruck, while the other is an ambulance. You can not compare them.

 

The exact combo these units of mine are running on. Both compliment the other quite well in determining what is to be investigated or ignored.

 

Thanks very much for the replies.

I was primarily interested in detecting whether a download was spyware before I installed it (right clicking in explorer to initiate a scan of the downloaded file like you mention).

What is the difference in function between A-Squared and SUPERAntispyware ?

Thanks again.

 

If the download is less than 10mb in size then you can get 25+ second opinions on it by uploading it to VirusTotal for malware checking.

Also Jotti service has 15MB max upload vs 15 databases.
