The balance between performance (low speed-impact) and real-time detection


In the past, a common complaint about antivirus programs was that they had a major impact on system performance, i.e. made the PC run more slowly in everyday use. Nowadays, anti-virus products use different optimization techniques to reduce system impact and disruption of everyday tasks.

In this blog post we want to answer the question as to whether any of the performance-enhancing measures taken by anti-virus vendors might have an impact on products’ ability to detect malware under some circumstances. To this end, we checked whether anti-virus products consistently detect malware in specific scenarios.

AV-Comparatives tests Anti-Virus Software protection against the Hermetic Wiper malware

Hermetic wiper malware

Austrian IT-security testing lab AV-Comparatives has tested protection against the recently-emerged Hermetic Wiper malware.  

The data-wiping malware has been used in international targeted attacks. Its aim is not to steal money or data, but simply to make victims’ computers unusable. To do this, it abuses the services of a legitimate company that makes disk partitioning software. This type of utility can create, modify and delete the data storage areas (partitions) of a computer’s system disk. Hermetic Wiper makes (unauthorised) use of this useful utility program to corrupt the system disk’s boot information, meaning that the computer cannot start up. The malware then overwrites the partitions on the disk, making the data on them unreadable, even if the disk is transferred to an uninfected computer.

Why you should never have multiple antivirus programs on your computer


Life is often about multiplicity. The more the merrier. Two heads are better than one. Strength in numbers. You get the idea. But when it comes to antivirus, it’s more a case of too many cooks in the kitchen.

We often hear from users who assumed that installing multiple antivirus solutions on their computer would improve their chances of detecting any malicious files before they do any damage. However, while it is a good idea to have multiple complimentary security products in place if you take your security seriously, this doesn’t extend to multiple full antivirus solutions. Having several antivirus products in place won’t do much to improve your machine’s security – in fact it’s likely to cause you some serious problems.

Mac vs Windows: is Apple really more secure? 


Mac or Windows? It feels like we’ve been debating over this for most part of the modern decade. Remember Apple’s “Get a Mac” campaign in 2006, where a personified Mac and Windows PC argued about who was the best operating system? Both companies have long been waging such marketing campaigns against each other to influence users.

It’s mostly down to personal preference, and we won’t weigh in. But one thing that does need to be taken out of the debate is cyber security.

Norton and Avira Ethereum Mining: Why Are AV Vendors Offering Crypto Services?


Avira and Norton are now offering customers the ability to mine cryptocurrency – for a fee.

Both AV vendors have introduced a new service which can mine Ethereum whenever a user’s computer is sitting idle. Customers will then be able to deposit any Ether their computer has mined into their own crypto wallet after giving NortonLifeLock, owner of both Avira and Norton, a 15% share of the proceeds. The crypto-mining services offered by both vendors are very similar, with the same rules applying to both Avira Crypto and Norton Crypto.
