I use ESET NOD32 Anti-Virus
and Emsisoft Anti-Malware
as they leave a small footprint...meaning they are not intrusive
and do not utilize a lot of system resources. ESET and Emsisoft Anti-Malware have exploit and behavior blocking features. Emsisoft uses advanced behavior blocking analysis
to continually monitor the behavior of all active programs looking for any anomalies that may be indicative of malicious activity.Emsisoft has the ability to detect unknown zero-day attacks
and file-encrypting malware (ransomware)
attacks. ESET Antivirus and Smart Security
uses Exploit Blocker
which is designed to fortify applications that are often exploited. ESET monitors the behavior of processes, looks for and blocks suspicious activities that are typical for exploits including. ESET's Java Exploit Blocker looks for and blocks attempts to exploit vulnerabilities in Java.
ESET and Emsisoft Anti-Malware also have the added advantage of blocking the installation of most Potentially Unwanted Programs (PUPs)
(such as adware
, unwanted toolbars
, browser hijackers
) if you enable that feature.
Keep in mind that an offer of free anti-virus software is essentially a marketing technique
...a way of advertising and enticement to get folks to try a product and if they like it, to purchase the full (or Pro) version which typically provides more features. Marketing and promotional strategies are built into the vendor's business model as part of their operating costs. Bottom line...it's all about generating revenue and finding new and creative ways to do so
. As such, users may have to deal with occasional nagging pop-ups or nuisance advertising and prompts to upgrade to the paid version.By using such free programs, you are essentially agreeing to the terms of the vendor's service which includes those ads.
In some cases you may be able to disable annoying pop-ups through the anti-virus settings if the vendor included an option to disable them. If the vendor does not have such an option listed, then your only alternative is to switch anti-virus software if the pop-up ads annoy you that much.
