Avast detected Chameleon as a hidden rootkit threat and quarentined it in the chest. Is this a false positive? To be honest, I have been having a really bad time with my laptop, starting with a lot of lag, then a BSOD. Unfortunate False Positives For every antivirus review I run a simple false positive sanity check by installing twenty-odd old PCMag utilities. Checks for unpatched applications. Can install and scan in Safe Mode. • Cons Middling score in malware-blocking test. Heuristic malware detection blocked some valid programs. Difficult to exclude wrongly-blocked programs. Phishing protection weak. • Bottom Line avast! Free Antivirus 2014 boasts a newly streamlined user interface and some interesting new features. ![]() With 200 million users it's definitely a contender in the free antivirus space. Unfortunate False Positives For every antivirus review I run a simple false positive sanity check by installing twenty-odd old PCMag utilities. None are digitally signed, and most perform some actions that might be considered suspicious, like installing Windows hooks or setting themselves to launch at every startup. This test reveals over-aggressive behavior-based detection by some antivirus products. S case, it turned up over-aggressive 'evolutionary generic' detection, Evo-Gen for short. The File System Shield quarantined two of the utilities on sight, the moment I clicked on them. It ran a DeepScreen evaluation on three others, but let them pass. Note that advanced users can enable the new Hardened mode at one of two levels. The Moderate level simply blocks any program that would have merited examination by DeepScreen, while the Aggressive level blocks any program with low prevalence. Also wiped out several of my hand-coded testing tools. Given that those tools are found nowhere but on my test computers, they're definitely of extremely low prevalence, so I can't blame avast! For suspecting them. However, I had quite a bit of trouble getting them excluded from future scans. The popup that reports detection of a suspicious file includes a link to put that file on the Exclusions list; it didn't work. I went into the Virus Chest (avast!' S name for quarantine) and chose the option to restore my program and put it on the Exclusions list. I verified that it appeared on the list. When I tried to run it again, avast! Whacked it again. In the end I had to mark my 'Tools' folder to be excluded from all scans. Malware Cleanup Choices Just about every antivirus gives you three scan choices: quick, full, and custom. Avast For Mac False Positive WebsiteYou can also choose a boot-time scan. The program itself will offer a boot-time scan after any scan that turns up malware. The boot-time scan's big virtue is that it runs before Windows is fully loaded, and hence before most (if not all) malicious processes are loaded. Note, though, that you need to keep an eye on it. The first time it detects a problem it will stop and wait for orders, and even if you choose an action for all items, it may stop again if it detects malware in the Windows folder. At the end of a regular scan, it reports what it found and awaits your confirmation that it's OK to proceed with cleanup. That does mean that if malware manages to abort the scan, cleanup won't happen. Avast For Mac Antivirus Free Download 2016I prefer an antivirus scan that wipes out threats as it finds them rather than waiting until the end. Unlike some antivirus products, avast! Can install and scan in Safe Mode, which may be enough to defeat malware that tries to block its installation. A bootable rescue disk (CD or USB) offers another line of defense, especially useful if ransomware has taken over the desktop. If all else fails, tech support can remote-control your system to get avast! Installed and working correctly. As I explained in a, I discovered that a rather nasty bot had taken up residence in my malware-infested test systems. I didn't put it there, but the existing malware samples invited it in. Rather than risk the possibility that my testing might have harmful effects, I'm now relying on the independent labs to evaluate how well antivirus products clean up malware. Fortunately, many of the labs now use the kind of hands-on real-world approach that I've always preferred. Avast For Mac Free DownloadWe have recent reports that some users are encountering the following message after recently updating or installing Avast anti-virus. The message appears in the lower right corner of this screenshot and causes and Unhandled Error message from Business Plan Pro: If you just installed our software, our installers are constantly scanned for viruses by enterprise level antivirus solutions so the chances are extremely low of that happening. For that to have happened there'd have to be a virus present on your system when you were downloading our installer so that the virus could infect our files. While this type of message could indicate that some of the files for your Business Plan Pro software have been infected by a virus, we have confirmation that is not the case at this time. Instead, this is a false positive message from Avast anti-virus due to some problematic virus definitions.
