Your computer processor is the brain of your system. If your processor runs at 100% capacity there could be a serious problem. Here’s why you should check your CPU.

Modern operating systems like Windows 7, Windows 8 and Mac have come a long way in terms of making the most of your computer’s processor. Multi-core processors have given computers a big boost too. These and many other factors mean your processor should rarely be used at 100% capacity. So what could it mean if your computer processor is being used at 99% or 100%?

1. A bitcoin mining virus has infected the system

Bitcoins are a fairly new form of online currency that can be transferred and used anywhere in the world. Bitcoins are generated using a computers processor. However imagine having access to tens if not hundreds of thousands of unsuspecting processors to generate bitcoins for you. This has motivated criminals to write bitcoin mining viruses that will use your computers processor to make them money.

2. Trojan infections on the computer

A trojan virus allows someone to connect to your computer over the internet. They can use trojans to view your screen, record anything you type on your keyboard, steal your files or casually browse the data on your computer. Trojan viruses are one of the leading causes of identity theft and can sometimes be very difficult to remove.

3. Software is malfunctioning or failing

As hard as they try, software publishers aren’t always able to keep their software up to date and working smoothly with the latest systems. Often times the publishers will rely on users to let them know when their software misbehaves so they can release an update or fix. High CPU usage can be a sign of a malfunctioning program so be sure to save your work often.

All managed services clients are automatically covered against high CPU usage. Here’s how you can check if your processor working too hard.

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.

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.

For more about updates or other issues affecting your PC, consult your local IT professionals.

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.
