Computer viruses can be classified into three main categories - virus that affects the boot sector of a computer, viruses that spread through macros and those that infect files. However, viruses are not the only ones affecting computer systems. There are other applications that can cause considerable damage. Examples include worms, adware, spyware, dialers, Trojans, etc.

They are executables that affect your system performance, can collect sensitive data and cause monetary damage or reputation loss.

Antivirus software helps to identify and remove all malicious applications including but not limited to viruses. They use scanning engines that can identify viruses by identifying the unique string of bytes that make up their composition. Most antivirus tools also study patterns to compare them with known traits of viruses. In case of infections, they are able to repair the files and in cases where repair is not feasible, they can quarantine the files or offer the option to delete the infected files from the system.

Your chosen antivirus solution should be able to offer you protection, at the minimum, from viruses that affect the boot sector, macro viruses, Trojans, worms and viruses that affect files. The other factors that might influence your decision of an antivirus solution are the speed and accuracy of the application and the usability.
These differ widely amongst vendors and you can do a feature by feature comparison before deciding on the application.

In the end, do remember that it pays to keep your antivirus software updated. With each passing day, more viruses are being created and released onto the computer networks. Most antivirus application developers keep researching and updating their application with the release of any known new virus or malware. Antivirus applications offer automatic updates or prompts whenever a new patch is available. It is advisable to avail the menu based definition updates or to opt-in for the updates whenever prompted to do so. Being on the safe side helps and it does when it concerns critical data that rests on your computer systems.

Spyware has become the most prominent computer security problem. How do you choose a good spyware removal tool? Beware of antispyware software which installs spyware/adware to your computer.

Spyware is a hidden software program. It is often used to monitor the browsing and shopping habits of computer users. Spyware can also be a remote control program that steals confidential banking and personal information.

Spyware has quickly become the most prominent internet security problem. According to the National Cyber Security Alliance, spyware infects more than 90% of home PCs. Recent survey shows that spyware is also sneaking into the network of corporate computers.

Spyware is often coupled with free downloads, such as free music, game and software downloads. Spyware may slow down computer, hijack homepage and create uncontrolled pop-up advertisements. Some spyware programs can remain unnoticed, secretly gathering information from the computer. Once installed, spyware is difficult to remove without the help of dedicated antispyware software.

Due to the rise of spyware activity, antispyware programs are in great demand these days. But are these spyware removal tools the same? Do they provide the security consumers need?

There are many reports that some antispyware programs installed their own spyware and adware to the computer. One consumer was quoted saying: “It’s a rip-off. I downloaded the free trial of an antispyware program, only to find out that it added its own adware to my computer.” Other consumers have complained that the antispyware program they use cannot detect all spyware programs. Some even slow down the computer and create pop-up advertisements.

There are a few good antispyware programs in the market today. On the other hand, dozens of spyware removal programs are blacklisted by consumers. Beware of spyware removal tools that are heavily promoted by e-mail campaigns. Never run any free downloads and free scans from unknown software publishers. Their programs may as well be spyware programs themselves. Read independent product reviews from renowned computer magazines or reputable sources. Spending some extra time in research can save you a lot of hassles in the long run.

Anti-spyware applications used to be ignored by Mac users. Aside from the fact that Mac is a highly secured OS compared to PC, the number of Mac users are not frequently the target of different attacks. The necessity of anti-spyware for Mac used to be debated since the addition of an anti-spyware is not that important as no one is really targeting Mac users. But those days are long gone.
Since the traditional spyware will not work for Mac, hackers have found another point of attack: phishing. This type of attack comes in the form of random emails or websites wherein they will ask personal information and eventually use them against the user. They could also use the information for unlawful means. The user will end up as a victim of identity theft.

The second scenario is through unknown downloads. Although Mac settings will require you to enter a password before you install any application, a shared computer will always be susceptible to different spyware. When everyone in your house can access your computer, you will never know the application they are downloading. Even the applications and plug-ins you are downloading might be infected with Mac spyware.

They might come in a form of friendly codec for your music player or a plug-in for your browser. As soon as the password is entered which allows the application to run, attacks could come in many forms – often unknown. Without you knowing it, Trojan could be installed wherein it could records keystrokes and capture screen activities. The mac spyware remover could delete the spyware but the damage might have been done as your actions could have been recorded and your personal information extracted.

Selecting the Right Anti-Spyware for Mac

There are two actions that you should be looking for in a mac anti spyware: prevention and detection. Macintosh spyware removal could be a good thing for your Mac but that only answers half the problem. Your software should also prevent any types of downloads with potential spyware or alert you about the spyware and would give you the option of allowing the spyware to run in your system or not.

Prevention is better than Cure

Mac anti-spyware may do its job in keeping you from different spyware. But remember that personal caution considerably helps in preventing different types of spyware. As the anti-spyware evolves, the developers of spyware are also working double time to defeat the latest versions of anti-spyware. If there’s anything suspicious regarding the application, website or email, better disregard them immediately. There are other secured sources you can consider. You just have to research a little bit more so that you’ll have a secured application for your Mac.

Two weeks ago strange things started to happen on my PC. The system was running extremely slow and every time I opened my browser pop-ups for online casinos and pc games came up.
Then, Firefox quit working. The Internet Explorer was working, but it was extremely slow and my homepage changed with every start. And hundreds of pop ups came out of nowhere.
Fortunately my antivirus program was still working. But it couldn’t detect any worms, Trojans Viruses or other malware. I didn’t know what to do. Maybe my antivirus program wasn’t that good was my next thought.

So I downloaded nearly every free antivirus program I could find online. I was ready to remove the Trojan virus on my computer. I ran the endless scans, but the results were disappointing.

There were some infections, which I instantly deleted – but no Trojan Viruses were found. I restarted the system several times but the symptoms were still there – the system was running awfully slow, pop ups were killing me, I was redirected every 10 seconds to some commercial sites…

And it got worse: now, some programs weren’t working (Word, ITunes). So I tried to post my problems in an online expert-forum.

The topic “How to remove a Trojan Virus” was quite popular, but it took some time, before somebody could give me some useful tips. Most people – including the experts – recommended me the program HiJackThis. This program scans the computer and creates a list of differences from a known spyware-free environment.

I ran the scan and even posted my log-file in the expert-forum. After one day, the “experts” told me there were no suspicious activities. I couldn’t believe it! I could feel there was a Trojan virus involved. The question “How to remove a Trojan virus” was already on my lips. But even HiJack couldn’t help me…?

The problem with HiJack is that it lists tons of processes running on your system. But that’s it! It’s up to you to decide which ones are “the bad ones” and need to be removed. And even worse: if you delete something wrong, it can cause significant damage to your system.

I was helpless and desperate – even the experts who studied several of my log-files couldn’t help me. And all the problems were still there – by now for some reason Opera quit working.

I was seriously thinking about buying a new PC! On the edge of despair, I read some reports from other guys in the online-forum who had the same problems – and successfully got rid of them. A lot of them were talking about a program called NoAdware – and how it helped them to find and remove the infections on their systems.

I had nothing to lose, so I gave it a try – particularly because the scan was free. Believe it or not – I was surprised. The program found 14 infections, among the Trojan Horses Vundo and ConHook and some Trojan-agents.

And the program was even able to delete them. I restarted the system and suddenly the all the programs worked like before – almost. There were no more pop ups and no more redirections to unknown sites. But the system was still a bit slow.

So I repeated the test. The result showed still some infections – but no Trojans. I pushed the delete-button and after the next restart - finally - my system was running like before. I couldn’t believe it. It was such a great feeling of relief.
I wish I had NoAdware on my system from the beginning and could save all the time I wasted trying to delete the Trojan horses on my own, endless reading and posting in online forums – not to mention all the bad emotions. :-(
