Cleaning up computers is our bread and butter, we see infected computers every day and are getting pretty good at determining the the main culprits when it comes to infection, so read on and I will give you our top three worst sources of infection.
Many people ask me why people create things like viruses and spyware for your computer and before I start explaining the sources of this material I should give my opinion as to why people are creating it in the first place. Malware (the heading under which all viruses spyware and other software that causes mischief comes under) can do just about anything to your computer, but generally it keeps itself to one of the following effects.
- It extracts information off your computer like passwords, e-mail address books or website browsing habits, with the purpose of using this information to market or make money from.
- It tries to take over your computer to make it do things like performing attacks on other computers to spread infection.
- It pops up or exposes you to some form of advertising for a product or service or something like that, often trying to make it so that the only way you can get rid of the message is to use your credit card.
As you can see the net result of doing these three things is making money plain and simple. The massive amount of time spent making malware and distributing it around the net is in my opinion an investment which by the looks of things has a very good return. If 1 million computers for example are affected by one of the pop-ups I'm talking about and only 1% of people try to use their credit cards to get rid of it, that's 10,000 people paying $29.95, not a bad payday I think. And how valuable is the browsing habits and e-mail address books of 1 million people, I would say many companies would be interested in that type of information. Basically it comes down to money, people create malware in my opinion to make money plain and simple.
Now, for some sources of infection:
Limewire - this is a filesharing program for downloading music (mostly illegally) and it is very popular around the world. Unfortunately many of the files that people download using this software have been infected in some way. So much so that if I run into a computer with limewire on it I can be almost certain that it will have some infection. The best way to avoid this infection is to not use the program and there are better alternatives available such as utorrent and bittorrent which have a lot less problems, however filesharing in of itself is a little dangerous as you never in really know what you are going to get so be careful.
Windows live messenger - this is an incredibly popular program which generally does not suffer too many problems until of course you accept files from others. Lots of kids, in fact I suspect all of them use this program and in general they aren't doing any harm. Chatting with your friends that does not necessarily lead to infection in your computer, sharing files however is entirely different. Infected files, whether they be music or programs or whatever are easily shared using messenger and this is its weakness in terms of infection. If you or your children are using messenger the best thing that you can do is tell them to not accept files from anyone else. Doing this should stop the infection coming in.
Porn - websites that deal with adult material and downloads of the same material are very often packed with infection. Porn accounts for a bigger slice of Internet traffic than anything else and that reason alone is enough to make one cautious as where there is traffic there is the opportunity to make money and that is the motivation behind people who create malware. As for the best way to avoid infection, apart from abstinence is to basically make sure you have good anti-virus and anti-spyware software installed. Unfortunately there is not much else you can do.
There are many other sources of infection that we have come across in our work but these are the top three that we have run into so far. In writing this I realise there is a lot more information I could give on this topic so I will finish by saying that I will be doing more blogs the sources of infection in the future.
