An antivirus program is a type of software that searches your hard drive and floppy disks for any known or potential viruses. The market for this kind of software has expanded because of Internet growth and the increasing use of the Internet by businesses associated with protecting their computer assets.
Antivirus software gives an essential layer of protection from a multitude of virus, trojan, worm, spyware, adware, dialer, keylogger and rootkit infections. Traditionally antivirus programs just detected infections and spyware removers just detected spyware but nowadays the boundary between antivirus and spyware removers is unclear. Most current antiviruses have at least reasonably good pick up rates of all forms of malware.
Malware involves viruses, trojans, worms, spyware, adware, dialers, keyloggers and rootkit threats that perform malicious tasks on a computer. With the huge climb in malware, antivirus programs cannot keep up with detecting all of it. But using more than one real-time antivirus employs much more system resources, can cause conflicts and even cut down protection. So I recommend you only choose one antivirus for real-time protection. Instead, you can grow your protection using other security programs.
Examining various free antivirus programs can aid in finding software which are vital in protecting your computer from virus threats and other types of malware. After doing a couple of searches you will find that Avira AntiVir is one of the top antivirus programs out there now.
Firstly, AntiVir does not include web or e-mail scanning options; this is only available in the paid version. The shortage of an e-mail scanner is not really a disadvantage, it just means that AntiVir won’t warn you of infected emails prior to opening them. But you must not read an infected email, AntiVir will still spring into action, so it doesn’t mean that you’re not protected from email-based viruses. Secondly, AntiVir has advertisements that come up with every update, you can disable or take these ads.
Finally, AntiVir has a time-limited license. It is renewable, but be aware that you’ll have to from time to time go through the hoops. Although AntiVir had signature updating problems in the past this seems to be fixed now.
