Preventing malware, and being resistant to the dangers of the Internet

Post by adj1993 on Sun Jan 09, 2011 1:15 pm

Introduction

Hackers and crackers,
malware writers, and cyber-criminals have a variety of motives for
installing malicious software using various methods and techniques to
spread their malicious programs: Who Writes Malicious Programs and Why?

Rogue security programs are one of the most common sources of malware infection and scams across the Internet. They infect machines by using social engineering
and other common scams to trick a user into spending money on a
security program, which claims to remove malware - but actually does the
opposite. These infections are responsible for launching unwanted pop
ups, advertising for rogue antispyware programs, and downloading more
malicious software.

Many variants typically use fake warning messages
and alerts on the Internet to indicate that your computer is infected
with spyware or has critical errors, which is a scare tactic to trick
you into downloading a malicious security application to fix it. The
alerts can mimic system messages so they appear as if they are generated
by the Windows Operating System.

The problem with these types of infections is that they can download other malicious software so the extent of the infection can vary, which make it more difficult to remove.

Infections are spread by using peer-to-peer
(P2P) file sharing programs. They are a security risk which can make
your computer more in danger of malware, remote attacks, exposure of
personal information, and identity theft. Malicious software such as: worms, backdoor Trojans IRCBots, and rootkits
spread across P2P file sharing networks. Infections also spread through
gaming, porn and underground sites. Users visiting such pages may see
cool-looking banner ads containing code that can trigger a drive-by
download and infection. Ads are a target for hackers because they offer a
stealthy way to distribute malware to a wide range of Internet users.
Infection can also spread through emails containing links to websites
that exploit your web browser’s security holes and by exploiting a vulnerability in older versions of Sun Java Runtime Environment (Java).

Prevention

Please
read the following information that I have provided, which will help
you prevent malicious software in the future. Please keep in mind,
malware is a continuous danger on the Internet. It is highly important to stay safe while browsing, to prevent re-infection.

Software recommendations

Free Antivirus

  • Microsoft Security Essentials:
    this is Microsoft's free antivirus/antispyware program. It equips you
    with protection against viruses, spyware, trojans, rootkits, and worms.
    It is also light on the computer's performance. Note: when installing
    this, you have both an antivirus and antispyware. Make sure you also get
    a firewall.
  • AVG Free:
    this is one of the most powerful, and easiest to use security software.
    The free version equips you with protection against viruses, spyware,
    trojans, rootkits, worms, and rogue software. Note: when installing
    this, you have both an antivirus and antispyware. Make sure you also get
    a firewall.
  • Avast!:
    this is an advanced malware removal antivirus program. The free version
    equips you with protection against viruses, spyware, trojans, rootkits,
    worms, and rogue software.
  • Avira Antivir:
    this is an advanced malware removal antivirus program. The free version
    equips you with protection against viruses, spyware, trojans, rootkits,
    worms, and rogue software.
  • Rising Antivirus: this is a lightweight, and great virus destroyer. It removes tough viruses, and even rootkits and trojans get destroyed.


Anti-Malware

  • Malwarebytes' Anti-Malware
    is a great malware removal program. It is recommended for anyone's
    arsenal. There is a paid version, which is highly recommended, but the
    program will work fully for free.


Free Firewalls

  • Tallemu Online Armor: the free version is just as good as the premium. I have linked you to the free version.
  • Comodo Firewall:
    the free version is just as good as the premium. I have linked you to
    the free version. The optional security suite enhances the firewall by
    40% increase. If you would like to install the suite that includes
    antivirus, then remove your old antivirus first.
  • PC Tools Firewall Plus: free and excellent firewall.
  • Outpost: another free and excellent firewall.


AntiSpyware

  • SpywareBlaster
    SpywareBlaster
    is a program that prevents spyware from installing on your computer. A
    tutorial on using SpywareBlaster may be found here.
  • Spybot - Search & Destroy.
    Spybot
    - Search & Destroy is a spyware and adware removal program. It also
    has realtime protection, TeaTimer to help safeguard your computer
    against spyware. (The link for Spybot - Search & Destroy contains a
    tutorial that will help you download, install, and begin using Spybot).


Note: Please keep ALL of these programs up-to-date and run them whenever you suspect a problem to prevent malware problems.

Resident Protection help
A
number of programs have resident protection and it is a good idea to
run the resident protection of one of each type of program to maintain
protection. However, it is important to run only one resident program of each type since they can conflict and become less effective. That means only one
antivirus, firewall, and scanning anti-spyware program at a time.
Passive protectors such as SpywareBlaster can be run with any of them.

Securing your computer

  • Windows Updates - It is very important to make sure that both Internet Explorer and Windows are kept current with the latest critical security patches from Microsoft. To do this just start Internet Explorer and select Tools > Windows Update, and follow the online instructions from there.
  • hpHosts file
    replaces your current HOSTS file with one containing well known ad
    sites and other bad sites. This prevents your computer from connecting
    to those sites by redirecting them to 127.0.0.1, which is your local
    computer's loopback address, meaning it will be difficult to infect your
    computer in the future.
  • Web-of-Trust
    is a browser extension for Internet Explorer, Mozilla Firefox, and
    Google Chrome. It warns you about sites that have a bad activity score,
    or just plain untrustworthy. It is a free warning tool, and will keep
    you from going to bad sites.
  • Disable Autorun: XP -- Vista/7.


Please consider using an alternate browser
Mozilla's
Firefox browser is a very good alternative. In addition to being
generally more secure than Internet Explorer, it has a very good
built-in popup blocker and add-ons, like Noscript, can make it even more
secure. Opera is another good option. Opera has great built-in security
features, and is a newer browsing experience. It also "fast-loads"
pages so you do not have to wait a long time for pages to load.
