Avast Prevention Test Videos

Last night I tested Avast Antivirus 4.8 Home against a few malicious URL’s and Exe’s and the results were less than perfect.  Avast let a trojan install on the PC and then couldn’t remove it once it was on.  Later the PC was turned into a BOT and started sending SPAM (video 2).

Here are some facts on the test since I know I’ll get questions: 

  • The PC was clean
  • Latest Avast was loaded
  • The Avast VPS was updated minutes before the video
  • All shields were all turned on high
  • 5-7 URLS were tested
  • 1 trojan infection was confirmed
  • 1 exe failed to elicit any response from Avast (silent malware/rootkit)
  • PC was turned into a spamming BOT

    Avast failed, no wonder for a free antivirus , maybe the paid version could do any better. For a free AV i think Avira is by far the best i used it too, so i can not wait for your test.But Avast at least detected that there were e-mails sent without user approval and this coul trigger the attention of aware use.

    The paid version WOULD NOT DO much better because it is the same features only with file sharing protection and email protection.

    All the other features remain the same with the exception of being able to use the advanced interface(like that is really worth over 20 dollars)

    did ok for a free antivirus, wonder how avira will do. i use to have avast now i have NIS 2009. friend gave me a key. 100% legal BTW, he works at best buy and they get free norton keys for promotion; he didnt need it so he gave it to me.

    Just like chris above me, I also used to use Avast. But now I use NIS 2009. Avast was okay and all, but I knew that it didn't pick up all the viruses on my computer.

    I do like NIS 2009 a lot better.

    Avast pro is probably the worst antivirus to buy, purely because the difference between the pro and free version are very fine. I also like NIS 2009 and used the 90day trial but it had an error which is didn't alert me to and stopped the realtime protection with no warning, so I switched back to nod32

    Jimmy James, how far along were you in the NIS 2009 trial when it stopped the realtime protection?

    I'm also using the 90 day trial. I have 80 days left and it's working fantastic.

    You call me fanatic, like you said in the video but one thing is being fanatic and another one not know the mechanics of the program properly.

    a) yes, it did indeed missed the first sample

    b) even though it failed to delete the partially downloaded component, that doesn't mean it was infected by that

    c) It did not really failed at the prevention. You got the popup about mass spam messages right?

    d) If you're performing any kind of tests you really should first "backtrace" the sample to verify later if it was executed and installed or nothing really happened.

    I know your tests aren't on the expert level but i really wouldn't expect something like this from you.

    To narrow this thing down. One sample got through, second one even though it was blocked by Web Shield it fell into a loop (that often happens with IE where you interupt a download and try to run it later).

    Technically, clicking "No action" for the moment and then initiating a full scan to clean remaining trash would do the trick ("No action" equals to "deny access")

    Suspicious emails popup shows something is going on and that you have to take actions. I think thats fair enough even if avast! alone cannot clean the mess. It warns you that not everything is ok.

    By the way, there is not antivirus that detect everything

    avast is a good little anti virus but indeed it dose miss alot of adweare and some trojans they need to add huristicts to there next build and a fire wall would be a very good thing

    @Alexis, you are right in saying that no antivirus that can detect everything but there are a lot more of them that has higher detection rates than avast.
