Protecting Your Personal Computer From Viruses

Malware software in computers is found all over the Internet. One should always remain conscious of downloading anything that is unfamiliar. Remember that any antivirus program can't give you a 100% virus protection. You should have the necessary skill in knowing how to prevent yourself from downloading virus infected files. Being a computer fanatic myself, I would like to share with you some useful advice on how you could protect your computer from getting virus infection and most especially how you could avoid downloading malicious files.

• Let's begin with getting e-mails. If you are unsure of the e-mail sender's identity, don't click it open, or seek help from someone you know.

• Never think about downloading all those keygens and program cracks. If you intend to keep your PC clean and free from infection, you should only buy your desired software from any authorized dealer. That way, you are sure to be free from any virus threat.

• Be sure that you use only the correct antivirus program. If you're the type who browses the Internet a lot, you have to confirm that you are using antivirus software developed especially to provide Internet security. There are several variations of anti-virus infection types. One example is the antivirus software which is solely created to scan e-mails. Another one is the "Trojan Removals," which as the name implies, are meant to eradicate Trojan horses.

• Stay away from using software from an unreliable source. For your own protection, it's better to use commercially available software either found in flash disks/DVDs or sent to your e-mail by a reputable seller.

If your task is to protect very secret data on your PC, then you must always opt to use a much secured operating program. There is a big discrepancy between each operating system and its corresponding security measures. A good example is Windows which is a good choice because it is compatible with several antivirus software, though the reason for this is that several viruses are targeted for it as well. If you don't feel comfortable enough on how you could avoid downloading an infected file and how you could be protected, it's advisable to use UNIX or Mac operating systems. Moreover, if you already know that your PC is infected, you have to quickly navigate over the Internet for useful information about the virus. You can type the information about this dilemma in countless search engines - there could be several users already sharing their advice. Otherwise, you can try to ask for assistance in forums which focuses on protecting your PC from viruses. Always be cautious, there are so many harmful Internet viruses and the number of victims has already increased dramatically.

Sohpos Anti-Virus For Mac Review - My Personal Experience

The full name is Sophos Anti-Virus For Mac Home Edition and this is an antivirus utility from Sophos who also supplies business strength solutions and represents that they are including the same function in this free version. This is a review of my personal experience installing and using the software so you can decide whether it may work well for you.

Anti-Virus For Mac?

Here are some reasons why you might want to consider installing antivirus software on the Mac. When Apple had the classic operating system, I always used antivirus just to be on the safe side. Even though I have always kept a complete backup and updated every day, an infection could be copied onto the backup all too easily. In those days it was Norton Antivirus, and even though I always updated the definitions there was never an issue.

With in the introduction of Mac OSX the character of the operating system changed because it was based on UNIX programming which is very stable and requires an administrator password to change core functions. For this reason it seemed unnecessary to use an antivirus program on modern Mac computers as long as one was careful not to open hoaxes in email or online.

Exploits That Circumvent Administrator Protection

Now that Apple has gained such huge size and recognition, new threats are beginning to appear. The Flashback exploit used a false Flash update installer and then evolved to exploit a flaw in the Java programming language. Apple released an update through the automatic software update to handle this but 600,000 machines had been infected. After the removal patch that number dropped very quickly. Still, it now could be possible to be at risk just by visiting a site online that is completely legitimate but has been compromised by hackers.

You can use a utility called Little Snitch that acts like a firewall for outgoing connections. The Flashback exploit checked and would not install on machines with LS already in place, because if the malicious program attempted to send passwords to a remote site it would be detected. Even so, it seemed wise to investigate using an antivirus program on the Mac, and CNET MacFixit which is very good at keeping users informed about the latest news, recommended installing such a program.

I had tried ESET Cybersecurity for Mac when it first came out and it put my computer in an endless loop and drove the processors up to maximum 100% as shown on the free utility Menu Meters, and the temperature began to climb so I uninstalled ESET. Newer versions may have improved, so you could use their free 30 day trial. ESET did find some Windows malware in suspicious emails that I had forwarded to authorities but neglected to delete from my SENT mail folder. Sophos ran the processors at 65-72 deg. C during a full scan, which is normal.

Sophos For Mac Results

So far Sophos antivirus for Mac has been perfect. It is easy to install, and even better, also easy to remove if needed. Before I installed ESET I read the forum posts for Sophos and there seemed to be some complaints, but a new version has now been released and the overall reports looked good.

I have found the processor use minimal and the scanning speed quick. The program automatically checks and downloads updated virus definitions hourly. A full disc scan of my 250GB hard drive took under two hours, for approximately 700,000 files. A menu bar icon shows status so you can instantly see your Mac is protected, and when definitions are being downloaded or a scan is in process. I'm glad to discover it has a fairly light footprint and generally stays out of the way while maintaining a live scan on all new files and programs.

Overall Sophos antivirus for Mac Home Edition has preformed flawlessly. I have no connection with the developer.

Daniel Dreifus has been using Mac computers daily since 1996. He began with the Performa 475 using a 25 MHz processor, 4MB RAM and a 40 MB hard drive. There was no connection to the Internet yet.
