How Did This Happen to Me? Top 10 Ways to Get Spyware or Viruses on Your Computer

If you use the internet, you have probably been infected with a virus, trojan or spyware. According to the SANS Internet Storm Center, the average unprotected PC is infected within 20 minutes of normal internet usage. Many people want to know what they did to get infected. Unfortunately, usually it was just one wrong click.

Here are the top reasons people get infected and how to prevent these common internet security threats.

10. Exchanging files in chat rooms.

You should never download files from sources you don’t trust. Viruses and other internet security threats can look like valid files or photos. Always scan files with a virus scanner before opening them.

9. Clicking on popup ads.

If you’re like most people, you probably don’t like popup ads. But whether you like them or not, you should never click on them. Popup ads can take you to a website that secretly downloads adware onto your computer. Enabling a popup blocker on your computer can help protect you. Some popups come from adware programs that have downloaded onto your computer, so if you still see popups after installing a popup blocker, scan your computer for spyware or adware.

8. Email attachments.

Viruses can be sent out as email attachments to infect your computer if you open them. If you download your email into an email program, scan all email attachments with a virus scanner. Most major webmail programs scan attachments before you download them, but you should still not download files from unknown sources. “Phishing” email, claiming to be from your bank or other financial institution which asks you to provide personal information or download something to your computer is another common email threat.

7. Instant messaging.

Because people are cautious with email attachments, new viruses are spreading through instant messaging programs. Infections look like valid files or photos, so always be careful accepting file transfers, even from sources you trust.

6. Downloading music.

Many websites that advertise free music downloads are loaded with spyware. You can even get spyware from these websites without manually starting a download. Other sites make you accept a spyware download to get the music you want.

5. Browsing websites.

Some websites use “drive-by downloads” – misleading dialogue boxes to secretly install spyware programs. Sometimes spyware can install even if you do not choose “yes” or “accept”. Keep your browser security settings on default to protect yourself against these infections.

4. Installing free programs or screen savers.

Check the license agreement of any program you install to confirm it does not come bundled with other programs. License agreements are supposed to explain if the software you are downloading will cause advertisements or other downloads. These programs may have long or confusing license agreements where they have buried this information. Always carefully read what you agree to before you download free software.

3. Adult-related websites.

Many of these sites make a profit by forcing viewers to download spyware and adware to access their site. You may not be able to view these sites if you are using a secure browser or have your security settings too high.

2. P2P programs like Kazaa or Limewire.

If you share music using peer-to-peer networks, you may be forced to download advertising software onto your computer. This software can generate popups from within your computer. In these cases, you may see popups even if you are not online.

1. Gaming websites.

It may seem that viewing spoilers for online games will let you win faster, but it can slow down your computer with spyware. Mick Lathrop, part of StopSign’s Spyware Research team says, “I get most of my spyware samples from gaming-related websites.” Avoid any site that requires a software download to access information.

Even if you have an anti-virus product on your computer, confirm that it protects against the growing threat of spyware. Enable a popup blocker and firewall for further protection. Using safe browsing habits and good security software can keep you safe on the internet.

7 Ways to Protect Yourself Online

Based on information provided on the Internet World Stats website, there are about 1.3 billion internet users worldwide. Some of these users are friendly people who want to enjoy entertaining themselves, communicating with friends and family, or researching and shopping. There are others who may be conducting business online and there are stil others who are there to harm your computer.

The Internet can be a great place to do a lot of great things, but special care should be taken to make sure conditions are as safe as possible.

Here they are:

1) Scan for viruses - It doesn't matter as much about what program you are using as it does how often you use it. Having the best virus software and never using it is about as bad as having no software at all. Computers can become infected in a number of different ways, so it makes sense to scan and scan often.

2) Scan for spyware - It's really not a great thing when someone can watch what you're doing from your home or business computer. Whether they are watching directly or indirecting, using software, caution should be taken to make sure spyware is removed.

3) Avoid internet scams - If it sounds too good to be true or if you're getting something for nothing, avoid it at all costs. There are probably scams being created every day that focus on people's emotions in order to persuade them to take some type of unwise action. If you fall for a scam, it can costs hundreds or thousands of dollars and can be hard to dispute if you try to prove that the actions were fraudulent.

4) Avoid hoaxes - Hoaxes play on people's emotions especially to forward emails that contain myths or folklore. Since the emails may sound like something that has actually occurred, people forward them and the process continues.

5) Report and Recognize Phishing - Phishing involves someone trying to obtain your personal information such as bank account information through cleverly designed emails and webpages. The best thing to do is to report these types of incidents to the necessary authorities. The key component is actually recognizing the phishing attempts. If you receive an email that asks for personal information or has a link to login to an account, avoid it 99% of the time. Most organizations will not ask for social security numbers, account numbers, or passwords from email.

6) Avoid pornography - The best solution for avoiding most pornography that exists on the web is to install a filter. One of the filters that I recommend can be found Bsafeonline.com.This will take care of most of the process. Inappropriate sites will be blocked and parents can take an active approach at controlling the internet use in their home.

7) Use caution when blogging - Blogging can be a great thing most of the time. It is great for search engine optimization and building communities online, but caution should be used when including information that is personal or when discussing details of other people's lives. In addition, to keep people from stalking you, I would not suggest chronicling every detail of your every day life.
