No AdWare Net

Posts Tagged ‘computer threats’

There are a number of indicators you can watch for which will suggest that your computer has been infected by spyware or adware. Please note that some of the symptoms listed below are not unique to just a spyware or an adware infection.

1) PC Performance – Both Spyware and adware consume your PC’s resource like computer memory. A bad spyware infection could dramatically slow your computer’s performance including causing your system’s to become increasingly unstable. Spyware also can affect your internet connection speed as it takes up bandwidth to communicate information back to its creator.

2) Pop up Ads – It is highly likely that your computer is infected by Adware if you notice more pop up ads appearing than usual. In some cases pop ads start appearing on the desktop even if you have not opened a web browser. Alternatively, search results may appear in a pop up or another browser window relative to the website you are visiting or keyword term you have typed into a search engine.

3) Browser Toolbars – These programs are commonly bundled with free software which the publisher often describes as ‘advertiser supported.’ The toolbar then feeds adverts based on the website you visit. They are usually very difficult to uninstall. ‘180 Search Assistant’ and ‘Huntbar’ are example programs.

4) Browser Settings – Your internet favourites or bookmarks and start page are two main settings which are targeted by spyware authors. Web sites are inserted into your list of internet favourites in the hope that you will visit them. Browser hijackers change the start page which is visited when the browser loads. Any unexpected change to your start page is a sign of infection.

5) Start Up Programs – Some spyware variants will try to add themselves to your Windows start up program list. If you boot up time becomes noticeably slower then review your program start up list to check for applications you are not familiar with and remove them. This program list can be review using the ‘MS Config’ option from the Windows XP Run command.

6) Software Failure – A spyware infection can cause some of your programs to crash or stop working. In particular watch if your Internet Explorer browser refuses to work all of a sudden.

7) Hosts File Changes – The Hosts File 1000 is a Windows file that maps the numerical IP Address to the Host Name very much like the address book on your cell phone ‘maps’ your friend’s name to their telephone number. Some spyware programs can change these setting so that when you type in ‘www.yahoo.com’ for example you are re-directed the spyware author’s website.

Keylogging software is an extremely dangerous spyware that can invade your PC. This is an invisible software program that cyber criminals use to track your online activity.

The major concern with this type of spyware is that you will not notice any slow down in your computer performance, it will run as normal. The Keylogging spyware will be quietly running in the background watching every keystroke you type.

The cyber criminals often sell your private information to third parties who then employ other techniques to withdraw from bank accounts and credit cards. Other sophisticated hackers use Keylogging spyware to invade company computers so they can steal vital business information. Some organizations have turned this situation around; they use Keylogging software to monitor employees activity within the workplace, so they can see what sites their employees are visiting during business hours.

Computer experts have said that because Keylogging software can hide deep within a computer it is almost impossible to detect. The traditional antivirus and antispyware that you see advertised free very rarely detects this software. Even the major paid versions find it difficult to locate and remove Keylogging software.

The number of crimes associated with Keylogging has been rising steadily over the last few years but there are proactive measures that you can take to prevent this software from attacking your PC.

You should be careful on the type of sites you visit especially if you download software, music or videos from the web. Keyloggers can easily attach themselves to other unsuspecting software, which in turn you download and install without realizing any thing is wrong. Online retailers and the major banks are relatively safe. Some good antispyware products install security blocks on your browser that alert you if you visit unsafe visits, these products also stop pop-up ads from appearing. Hackers use these ads to get access to your PC; if you are unsure, the best thing to do is not to click on these pop-ups.

It is essential when surfing the web that you have an active firewall in place to prevent unauthorized access from potential hackers. Nowadays, most people know what spam is and usually have some form of spam filter in place to delete these emails. However, cyber criminals are constantly looking for ways to cir 1000 cumvent antispam filters. They use different tactics so that some emails appear to be genuine, the advice here is that you should be wary of emails if you do not recognize the sender, carefully read the subject and never open any emails with attachments.

Computer security threats have cost most people around $2000 to buy a new laptop. When the threats are infecting their computer, they cannot do anything and have to buy a new computer. Have you ever wondering why your computer is running slow? Or why your memory usage is always 100%? Or are you getting the same pop-up every time you open your web browser? These are caused by the nasty threats that lurk in your computer.

Therefore, computer security is important to all Internet users. These threats bring nothing but trouble and it can also cost you your personal and confidential information. There are ways to remove the threats that didn’t cost you near a price of a laptop. But, before you learn how to remove the threats, first you must know what the threats are.

In this article, I will explain ten must-know threats for any computer and Internet users.

1. Internet Worms

Internet worms are programs that can affect another computer on the same network and it works differently from virus. It doesn’t need to attach itself to another programs to be harmful and can create an exact copy of itself. Worms spread via network and consume bandwidth. Have you ever wondering why your network connection becomes so slow? It might be because of the worms. Worms can have many malicious effects such as causing a server to crash, make a user’s files unusable, or creating a backdoor on target computer.

2. Rootkit

Rootkit can hide it presence in a computer and can avoid detection while running its utilities. It can create a backdoor on target computer and allow hacker to send spam emails or use the target computer to perform denial-of-service attack on servers. Detecting it is difficult as it can conceal its presence in a computer. One way to detect it is by running virus scanner while it’s not running. In this case, running the antivirus before the system boots the hard disk.

3. Zombies

When a virus or trojan has infected a user’s computer, it will open a ‘backdoor’ to allow hackers use the infected computer for malicious purpose without the owner knowledge. This infected computer is called the zombie. Furthermore, the hacker can sell the target computer access to others and others can use if for their own p 1000 urpose. If a spammer has gained an access to the target computer, it will use it to send spam.

4. Browser Hijacker

A browser hijacker can change your browser home page or search pages in your browser. In worse cases, it can disable your internet option so you cannot change the home page to the default home page. Furthermore, the browser hijacker can edit the registry so it can run every time you restart the Windows.

5. Email Virus

Email virus can distribute itself using email as an attachment. When you open the attachment, it will launch the virus and the virus will use the target computer to send the same email with the same attachment to other computer. It can also find files containing email addresses in the target computer and send the same email to the email addresses that it found. Sometimes, it can launch itself when the user views the email even though the user didn’t launch the attachment.

6. Mousetrapping

Was there a time when you cannot leave a website? This is called mousetrapping. The website will use a script preventing the Internet user from leaving the website. Sometimes, it will open a new browser and will display the same website. In order to prevent this from happening, you need to disable java script so the script no longer working.

7. Phishing

This is another threat that we faced online. Phishing is a term comes from fishing because the phisher will try to obtain your private information using bogus emails or bogus websites. If the phishers want to obtain your PayPal username and password, they will create a website that is the exact copy of PayPal and will email you asking you to enter your username and password using the link provided. The link they provided in the email will not go to PayPal, instead, it will go to the phishing website and if you enter your username and password, they will use it to get your money out of PayPal.

8. Spam

Spam is the junk emails or bulk emails send by the spammer to numerous recipients aimed to advertise something, scam, or sending virus. Spam can disguise itself as a personal email to bypass the spam blocker. Some spams do no harm but it’s a waste of time deleting it and it’s also annoying.

9. Spyware

A spyware is software used by hackers and advertisers to gain information about you. When visiting certain websites, you’re asked to install this type of software or updates that you need and the updates that you installed are actually spyware. Spyware can also install itself in your computer and it consumes memory usage and will slow down your computer.

10. Adware

Software that displays advertisement in your computer is adware and some of it installed itself in your computer without you knowing. However, not all adware are bad. Some of it is used to advertise something to fund the company. This type of adware will ask and tell you that they will install software that will display related advertisement in your computer. But, adware is a problem if it’s too difficult to uninstall, or it installed itself without you knowing, or it hijack your web browser and slow down your computer. This type of adware needs to be removed.
