How to Defend Your Computer From Malware

By on May 5, 2012 in Antivirus, Computers |

Malware refers to all the kinds of software that you don’t want on your computer. This extends well beyond just viruses to things like spyware that can steel your private and personal details and adware which can cause pop ups to spring up on your screen. On top of this of course it applies to viruses as well which we all know can cause any amount of damage to our computer. This malware of course is malicious and was created with the intention of either helping someone to further their goals of self promotion, or literally just to frustrate you (there are people out there with this much time on their hands and all we can do is feel sorry for them). Regardless of the motive however, unanimously none of us wants to have malware on our system, and prevention is better than cure – so how do you go about avoiding it? Where Does Malware Come From?Malicious software can come from a number of different sources and there are many scenarios where you might unintentionally download something that can harm or slow down your computer. Identifying these and then avoiding them is of course the best way to keep your PC running smoothly. One such situation in which malware is a common problem is when surfing the web. Various websites can infect your computer with unwanted files, and these are generally sites that are providing already ‘dubious’ content. If the site you are viewing is sharing illegal downloads then for instance, or on a very alternative subject, then you increase your chances of malware. The most obvious way to avoid this issue is of course to stick to respectable sites that you know won’t be carrying harmful files. At the same time, by using a good browser such as Firefox you can avoid certain dangerous files, while plugins can help further this by scanning pages for potential harm. Another source of malware is file sharing. File sharing means things like torrents or P2P software that allows you to download files directly from other people’s computers. This is often used to illegally obtain films and games, but these can also provide a ‘Trojan horse’ for malware. If you want to avoid falling victim to this ruse, one option is of course to simply avoid using file sharing in the first place. Meanwhile you should be careful to read reviews of torrents before you start to download them, and you should run any files you do download through a virus checker first. Malware can also come in e-mails, and this is one of the ways that some malicious files can proliferate – by hacking your e-mail then messaging other people. Never open attachments such as .exe’s unless you are absolutely certain you know what they are and have first spoken to the person who sent it. Likewise you should still be sure to run the files through virus checkers. More Defensive MeasuresHaving a good virus checker/anti spyware software is a good way to help yourself from spyware and adware. You should also be sure to use this to run regular checks and keep your computer clean in other ways too with registry checks and by deleting unwanted files and installing updates. A little ‘spring cleaning’ can go a long way to help you avoid all sorts of unwanted software.

Computer Protection through Internet Security Firewalls

By on Nov 9, 2011 in Antivirus, Computers, Internet |

Computers that do not have firewalls are vulnerable to hackers’ attacks, viruses and spyware. This is why it is mandatory to have a firewall installed on your computer to make sure that your internet connectivity is secured. Using a firewall is considered one of the best ways that will lead to a computer protection. Firewall is defined as security software which is known to operate in such a manner that it can stop unauthorized access, while at the same time allowing other genuine people or software to connect securely to the internet. In case an outside attempt is detected, the software will block and encrypt the attempt that is on its course of happening. This seems to be one of the best means to keep yourself protected against spyware, viruses, malware that tries to connect to network or internet. Regardless if you have installed an antispyware or antivirus system, a firewall is necessary to have on your device. Some of the operating systems, such as Windows Vista and XP come with already installed internet security firewalls, they are actually built-in right from the start. When you operate the system make sure that the firewall is on as it can keep your computer protected from harming elements. There are on the market many antivirus companies that provide firewalls and as such users can disable the firewalls that come with their operating system and install a new, more efficient one. Installing a firewall is mostly recommended if your computer operates on a network. Installing a firewall in each and every computer means that the entire network is protected and will keep malware from attacking every computers on the network. Firewalls are known to exist in two types – software firewalls and hardware firewalls. The first ones block any communication on your computer that is unauthorized. The second one, hardware firewall is installed between computer and router/modem which will not allow any communication that is illicit to happen to your system. Nowadays there is no such thing as a computer that is connected to internet and not requiring a firewall protection. Several renowned antivirus brands such as Symantec, AVG, McAfee are selling firewalls online. But before reaching to these ones, you should check first if your device is equipped with such a security. In case it doesn’t have one, then you should install one as soon as you can if you want to keep your system free from the different malwares that are present on the internet.

It is always better to prevent than to cure, as an old saying goes, this one applying as well to computer security as it does with any other field. Everyone using a computer connected to internet knows that this device can be exposed to virus and malware attack even when least expected. Knowing all these, you should do your best in finding ways to keep your computer protected. One of the constant threats that seem to stand the test of time and anti-malware tools is Zeus.

Avira AntiVir system is another product that is not very popular with many users; it can be found for free and under paid version as well. Some reviews describe this system as a very efficient one since many viruses have been detected which have been overlooked by other famous antivirus tools. ClamAV is used as a product for those who maintain or host email gateways based on Linux. Lately this product will come also for the Windows version. Another antivirus and rootkit tool for your computer security is Avast, which is offered for free, but comes as well with paid version once you need additional characteristics presented with it. CheckPoint Software Technologies has bought a few years ago an antivirus product called ZoneAlarm because they have found it a helpful tool for providing the needed firewall while a desktop security product was added to it. The features included in ZoneAlarm are quite impressive, not to mention that recently new features were added one of them being known as DataLock.
