AVAST 4 Home Edition

About.com Rating 4 Star Rating
User Rating 3.5 Star Rating (5 Reviews)


The Bottom Line

AVAST 4 Home Edition provides free antivirus protection for Windows XP/2000/NT/ME/98. The scanner installed just under 40MB and 6 running processes to our Windows XP Pentium 4 test system, taking a slightly bigger toll than other free antivirus scanners, but still well suited for older PCs or those with limited system resources.


  • Small footprint ideal for even older PCs
  • Scan on bootup helps thwart resuscitators
  • Removes some adware and spyware


  • WinAmp-style interface may not appeal to all users


  • AVAST 4 Home Edition is a free antivirus scanner.
  • Support options are limited, but this is increasingly the case with even paid-for scanners.
  • Sports standard antivirus features, plus adware and spyware removal.

Guide Review - AVAST 4 Home Edition

AVAST 4 Home Edition installs an interface that could be described as either clever or cumbersome, depending on your point of view. Borrowing on the WinAmp-style skins, the look can be changed by downloading a new skin from the vendor's website. Regardless of the skin, however, it's less than intuitive for those who prefer a standard Windows interface with easy-to-browse menus. AVAST 4 Home Edition is the only one of the free scanners to offer scans on bootup. This can greatly increase the chance of removing stubborn infectors, particularly those that use resuscitators to thwart removal attempts. (Each of the free scanners can be run in Safe Mode, however).

AVAST 4 Home Edition provided limited adware and spyware removal, nabbing 33% of the active components we tracked on our test system. Though 33% is certainly a poor removal rate, it is the only one of the free antivirus scanners to offer adware and spyware removal - and is one of the few to do so even among paid-for antivirus scanners. Further, the deficiency appeared to be due to a lack of signatures, rather than any particular struggle to remove infectors. (Indeed, the scan on bootup option virtually ensures AVAST an easier time of removing adware and spyware, provided the appropriate signature is in place).

Alwil Software, makers of AVAST, offers support for the free version via email, online help forums and knowledgebases.

avast is better than other paid antivirus software, Member grnyel

I recently got viruses infection on my computer (it comes no where with Antivirus malware and system defragmenter getting into my computer and make my system restore disfunctional and some key root commands paralyzed) and lost cmd, sfc, even system resotore... and I have tried to work every way to correct it and tried to get rid of viruses including get to registers to remove the mal registers based on suggestion googled and found in internet but constantly got 0xc000142 error, I tried Macafee (Paid), AVG 8.5, Anitmalware, spybolt etc. the MaCafee gave me no error, antimalware and spybolt remove few, it is avast removed the viruses and restore my cmd and sfc and others and make 0x000142 go away. It is especially powerful by doing the boot scanning even after doing full scan. I am more agree on CNET's assessment giving it a 5 stars, this is the antivirus, I am willing to spend money for. no kidding, though it is a free spyware. I don't agree at this article's assessment.
