3 Reasons to Block Advertising on your PC

Does advertising improve your web browsing experience or make it worse? Even legitimate advertising can cause major headaches to major infections.

Advertising can be a great source of revenue for websites that offer content and information for free. Major websites that you use everyday have taken this to an extreme by serving up video ads that talk to you and track your online behavior. However the more websites rely on advertising for their revenue the more willing they will let any run an ad on their networks. Here are three reasons why advertising has reached a point where it can be a threat to the average user browsing the internet.

1. Malware spreads through legitimate advertising

There have been many cases in the last few years where hackers and criminals have used legitimate advertising and banners in websites and in videos to spread their malware. One example is a bitcoin mining virus being spread through Yahoo advertising. Even Youtube fell victim to advertising serving up remote code execution. These major website quickly patched up the problem but it will take more than a break-fix approach to end this cat and mouse game.

2. Are you really getting what you click on?

Accidentally clicking on the wrong link when you want to download a song, file or program from the internet can open the flood gates of junk on your computer. The above image shows a legitimate download website. Can you guess which link is the correct link to download your program?

3. Popups, search engine hijackers and junk programs

Once junk programs from advertising get their foot in the door, it can be very difficult to detect or even remove the software. The above search engine may look like Google, but it is a knock off website meant to steer you to their partners websites.

For now until major websites have better safeguards in place to prevent malware, junk programs and sneaky advertising methods from their ad networks it’s better to steer clear from advertising all together. We recommend running Firefox or Chrome with ad block plugins installed.

How to Check For Updates in Windows

To maintain a secure and functioning system, it’s important to keep your system up to date. Here’s how you can check for updates in Windows.

It’s easy to check

In Windows 7 or Vista, click the Start button and, in the search box, type Windows Update.

In Windows 8, drag the mouse to the right edge of the screen, click the search charm that appears, and type Windows Update.

Click Windows Update when it appears on the menu. You should then get a screen that looks like this:

To review the updates that are available, you can click on the blue text representing the optional and important updates respectively.

The next screen allows you to check the boxes of the updates you wish to install.

We recommend that you install all the important updates and almost all of the optional ones. The optional update we counsel against is the Bing bar, which introduces a toolbar that you definitely do not need.

Once you have checked all the updates you want, click Install to go back to the previous screen where you click Install updates to get the process started.

Set Windows to install important updates automatically

You can check this setting on the same screen on which you installed Windows updates. Look to the left margin, and you should see a link to Change settings.

For Important updates, use the drag- down menu to Install updates automatically (recommended).

Installing important updates automatically will keep the critical security fixes off the back burner and readily available to ward off viruses.

Why You Need Windows Updates

Do you feel nagged for updates by Windows? As annoying as they may be, here are 3 reasons it’s necessary to keep your systems up to date.

Your reservations to install updates are understandable, especially when these updates can sometimes introduce glitches and even hijack your system for repeated restarts. However, no matter how annoying they can sometimes be, updates are essential for your Windows system to function optimally.

1. Most Windows updates address security issues

Neglecting updates is a surefire way to compromise your operating system with infections that can slow down your system and even allow remote users to steal your private information. Moreover, the main reason Windows PCs succumb to malware and other viruses is that users neglect installing updates. One particularly pernicious infection is the CryptoLocker virus that allows remote attackers to ransom your personal folders.

2. Updates can fix bugs that prevent Windows from functioning properly

These bugs can sometimes slow down your computer or cause your system to freeze. Windows updates often have hotfixes that address these bugs. Bypassing the installation of these hotfixes puts the stability and performance of your system in jeopardy.

3. Updates let you upgrade your existing Microsoft software or get new features

These features include Net Framework and Silverlight, which allow other programs, including non- Windows ones, to work properly. Software upgrades often add additional features to Internet Explorer and Microsoft Office, making them more user- friendly.

Note, that updates are no longer available for Windows XP. We therefore recommend upgrading to a newer version of Windows if you are running XP. Now that you know the importance of updates, do you have the latest ones installed?

How to Detect Bitcoin Malware on your PC

Does your computer seem to running much slower than usual? If so, someone may be using your computer’s processing power to mine bitcoins.

This is precisely what bitcoin mining viruses do, yet many of them can be detected with antivirus programs. Malwarebytes is highly recommended for this purpose. Whether your antivirus program is Malwarebytes which we recommend or something else, running a scan every so often will allay infection concerns.

Another way to detect bitcoin malware is by looking at the processes running on your PC. In Windows, hold down the Ctrl and Alt keys while pressing Delete. This will give you the following menu:

Select Start Task Manager from the list of options.

In the Task Manager, select the Processes tab as shown above. Check for any that have unfamiliar names, use a lot of memory or a high percentage of the CPU. You can sort the list by memory and CPU usage by clicking the CPU and Mem Usage column bars at the top. Look up any process with an unfamiliar name on Google.

If the Google search reveals the name to belong to a rogue process, here’s how to remove it from your system.

In addition to being detected by antivirus scanners and causing your PC to use too much of its resources, bitcoin mining viruses can possibly make your computers use more electricity.

All managed services clients are automatically protected against processes that use too much CPU, including bitcoin malware. Although bitcoin mining software on your PC isn’t likely to damage your files, you should always be running a backup to keep your files protected from catastrophic data loss.

Make Windows 8 Look Like Windows 7

Are you disappointed with the new unfamiliar Windows 8 or 8.1 interface? Here’s how you can make Windows 8 look like Windows 7.

Fortunately, there are ways to get Windows 8 to act like the Windows interface you know and love.

Probably the most off- putting aspect of Windows 8 is the lack of a Start Menu. With that in mind, the first order of business is installing a third- party Start Menu program. We recommend Classic Shell. Aside from being free, it offers one of the closest approximations to the Windows 7 Start Menu obtainable from any third- party app. It can be downloaded here.

When setting up Classic Shell, go to the Start Menu Style tab and select Windows 7 Style.

Under the Basic Settings tab, check the Skip Metro Screen box.

This will ensure that you will go straight to the desktop without having to view the media saturated greeting screen that looks like this:

As annoying as that greeting screen is the charms bar shown below.

To disable this, download the free Winaero Charms Bar Killer. Launch the application. It will go to the notification area. Right click the program’s icon in the notification area and select Kill Charms Bar.

This will disable all those annoying charms and allow your computer to behave like a desktop rather than a tablet.
