Use Security Software That Updates Automatically

The bad guys constantly develop new ways to attack your computer, so your security software must be up-to-date to protect against the latest threats. Most security software can update automatically; set yours to do so. You can find free security software from well-known companies. Also, set your operating system and web browser to update automatically. If you let your operating system, web browser, or security software get out-of-date, criminals could sneak their bad programs – malware – onto your computer and use it to secretly break into other computers, send spam, or spy on your online activities. There are steps you can take to detect and get rid of malware. Don’t buy security software in response to unexpected pop-up messages or emails, especially messages that claim to have scanned your computer and found malware. Scammers send messages like these to try to get you to buy worthless software, or worse, to “break and enter” your computer.

Panda Cloud Antivirus

Panda Cloud Antivirus is Panda's successful attempt to jump on the free antivirus bandwagon. Along with MSE, it is an excellent choice for average users with a simple interface and completely automated features with automatic updating and removal of malware. The detection level is generally very high, but according to the latest test data, detection of zero day threats is slightly lower. PCA uses 'cloud' technology to provide for a much quicker release of updates as all definitions are stored in the cloud and thus the moment Panda updates their blacklist all users of PCA with an internet connection are protected from it. Panda Cloud Antivirus has a behavioural blocker and web protection, which will certainly increase your security. However as you can simply use one of the other free AV's with a separate behavioural blocker (for further details see our Security Wizard) to achieve possibly even better protection, this is not necessarily an advantage. One minor reservation I have is that PCA seems to erroneously detect certain browser/system-related applications, for example VideoCacheView, and because of the automatic quarantine this made it a fraction bothersome.

Microsoft Security Essentials

Microsoft Security Essentials is a favorite of mine with great detection rates, particularly for rootkits. Even more impressive is the fact that Microsoft Security Essentials has very few false positives, is light on resources and is good at removal of existing malware. MSE is a great choice for average users because of the minimal user interaction required. It automatically updates and removes threats. No registration is needed, apart from a quick validating of Windows, and there are no nag screens or advertisements. The main downsides are the slow scan speeds and the lengthy amount of time it takes to quarantine malware, though in my opinion these are rather trivial concerns, as for example a scan just be run overnight. MSE also is not available in certain countries so users there will have to look elsewhere. Note that Microsoft Security Essentials requires a genuine copy of Windows to install.
