Currently I’m using Avast! 4.6 (latest version) as my only anti-virus-prog because it’s ressource friendly (at least the processor load seems to be lower than with antivir 7 premium or kaspersky - you can check this with Aquamark 3 :D) and the implementation in the OS & Web is the best which I have seen in an antivirus-prog until now
But it is said that avast! does have problems detecting certain virusses (like trojans, malware, spyware etc.)
So my question is now: What kind of “bad things” does avast home scan for? I heard that there is no script scanning included in the home version - isn’t this a serious security problem?
Another question is what’s the difference between deep scan and normal scan. Does deep scan scan all files on the HD? The deep scan takes very long (1h 45min) on my PC while the deep scan (scan all files incl. packed) on antivir 7 premium only takes 30min. For example the scanning of a very large video file (*.avi) takes years ^^ (the scanned file counter doesn’t move).
I hope you understand my English and can answer my questions ^^
Hi,
Having no script blocker is only really a problem if you use programs such as Microsoft Excel, Word etc that use scripts such as Visual Basic. However, you can download Microsoft Antispyware Beta (which is now called Windows Defender Beta 2) - for free - which has script blocking.
Avast detects Trojans, Worms, and Viruses. Avast have said they are working on the detection capabilities of the software - and avast has won a number of awards for their detection capabilities.
A deep scan will scan every file on the computer whereas a normal scan only scans files which are most at risk from viruses. Although the scan takes very long Avast have said they are working on reducing this.
avast! detects malicious spyware- spyware from the criminal end of the spectrum- like keyloggers, Trojan horses, spyware designed to steal personal information etc.
I don’t believe it attempts to detect spyware from the more ‘commercial’ end of the spectrum- adware and spyware designed to track which sites you visit so adware can target specific ads at you.
There are AV’s which attempt to detect and remove all spyware, but they have to deal with lawsuits from adware firms that don’t want their products removed.
Some AV’s that try this don’t have a very good record for removal anyway, and others just use a licensed version of Ad-Aware.
You’ll be fine with avast! and the free version of Ad-Aware, plus Spybot Search and Destroy. For real time protection, Microsoft AntiSpyware is good, so are the commercial products from Webroot and Sunbelt, if you feel like spending some money.
avast! doesn’t have a brilliant detection rate for Trojans (yet?) but combining avast! with Ewido and a-Squared (both free scanners) you can get a detection rate equalling the best scanners.
I believe most people don’t understand what avast! Script Blocker really does (it doesn’t really have much to do with Excel, Word, etc. - only with IE). In any case, since the introduction of WebShield it became quite an obsolete feature, as the Web Shield will detect mostly everything the Script Blocker would, and more.
I must say I’m not aware of any scan speed improvements in progress (where did you read that, Mike?). I would say, however, that using the “Thorough scan” is overkill in most cases. The Thorough scan checks the whole files and all the files - that’s why it takes so long (other AVs may not even have that possibility, I don’t know). Using the “Standard scan”, possibly with archives enabled, should be just fine. If you really want the thorough scan, don’t be surprised it’s slow.
