Warning signs your computer has malware

With the rise of eCommerce and online banking, cybercrime has evolved. Like criminals who pull smash-and-grab jobs, they go where the money is. However, unlike bank robbers, cybercriminals do their best to avoid detection by letting malware do the work for them. Viruses and ransomware sneak into PCs to quietly steal passwords, financial credentials, and other personal information to be sold on the black market for profit. Not all malware is stealthy though. Here are some telltale signs.

Slow computer

Are your operating systems and programs taking a while to start up? Is your data bandwidth suspiciously slow? If so, your computer may potentially have a virus.

However, just because your PC is running slower than usual doesn’t necessarily mean that it’s infected, as there could be other causes to your computer slowing down. First, check if you’re running out of RAM. For Windows, open task manager (press Ctrl + Shift + Esc) and go to the Performance tab and check how many gigabytes of RAM are used up under the Memory section. For Mac OS users, you can open the Activity Monitor app and, under System Memory, you should be able to find out your RAM usage.

Other causes could include lack of space on your hard drive or even damaged hardware. Once you’ve ruled out other possible causes, then malware may have infected your device.

Blue screen of death (BSOD)

If your PC crashes regularly, it’s usually either a technical problem with your system or a malware infection. You might not have installed the latest drivers for your device or the programs you’re running could possibly be incompatible with your hardware. If none of these problems are apparent in your PC, then a virus could be clashing with other programs and causing your crashes.
To check what caused your last BSOD, go to Control Panel > System and Security > Administrative Tools > Event Viewer and select Windows Logs. Those marked with “error” are your recorded crashes. For troubleshooting solutions, consult forums or your IT department to figure out what to do next.

Lack of storage space

There are several types of malware that can manipulate and corrupt the files saved on your computer. Most tend to fill up your hard drive with suspicious files. Ransomware, for example, is a notorious type of malware that denies you access to your data until you pay a so-called ransom. There are more aggressive forms of ransomware, like NotPetya, known for exploiting security holes to infect computers without needing to trick users.

If you find any unknown programs that you have never installed before, notify IT personnel in person immediately (do not email them) and have them handle the situation for you. Your device might not be the only one in your network that is infected with suspicious programs.

Suspicious modem and hard drive activity

Combined with the other warning signs, if your hard disk is working excessively while no programs are currently running or if you notice that your external modem is always lit, then you should scan your computer for viruses.

Pop-ups, websites, toolbars, and other unwanted programs

Pop-ups come from clicking on suspicious pages, such as those where users are asked to answer survey questions to access a website’s service or install free applications. While they’re inherently harmless, they could be downright annoying. Refrain from clicking pop-up pages and just close them instead. Run malware scans and update your browsers.

You might think that downloading free applications is harmless, but the installation process can inject malware into your device. When you’re installing a program from the internet or even app stores, it’s easy to just skim over the terms and conditions page and repeatedly press next. This is where they get you. In the process of skipping over certain installation steps, you might have agreed to accepting a new default browser and opening unwanted websites and other programs filled with viruses. Be cautious when downloading something for free.

You’re sending out spam

If your friends are telling you that you’ve been sending them suspicious messages and links over social media or email, you might be a victim of spyware. Warn your friends not to open anything that appears to be spam and make sure to reset your passwords across all your devices and enable multifactor authentication.

Knowing how malicious software affects your computer can help you take the necessary precautions and steps to rectify the situation as soon as possible. Regardless of whether or not your system has experienced these symptoms, it’s always smart to perform regular malware scans to ensure your business is safe.

Dealing with hypervisors’ vulnerabilities

Hypervisors have changed the game of cybersecurity. They provide unmatched cyber protection for your data as they keep it in the cloud. However, hypervisors still have vulnerabilities that hackers can exploit. Find out how their weak points can be addressed.

A hypervisor is a software application that distributes computing resources (e.g., processing power, RAM, storage) into virtual machines (VMs), which can then be delivered to other computers in a network. This gives people the resources they need to run resource-intensive applications without having to rely on powerful and expensive desktop computers.

System administrators can also use a hypervisor to monitor and manage VMs. So if hackers manage to compromise hypervisor software, they’ll have unfettered access to every VM and the data stored on them.

While hypervisors are generally well-protected and robust, security experts say hackers will eventually find a bug in the software. So far, there have been limited reports of hypervisor hacks; but in theory, cybercriminals could run a program that can break out of a VM and interact directly with the hypervisor. From there, they can control everything, from access privileges to computing resources.

Another point of vulnerability is the network. Since hypervisors distribute VMs via the company network, they can be susceptible to remove intrusions and denial-of-service attacks if you don’t have the right protections in place.

If those attack methods aren’t possible, hackers can always break into server rooms and compromise the hypervisor directly. So what can you do to protect against these threats?

Create separate VM and management networks

Keeping your VM network away from your management network is a great way to secure your virtualized environment. If malware compromises your VMs, it won’t be able to affect your hypervisor.

Set access privileges

Ideally, only you, your system administrator, or virtualization provider should have access to your hypervisor console. You need to set strict access restrictions on the software to prevent unauthorized users from messing with VM settings and viewing your most sensitive data.

Disable unnecessary services

Off-the-shelf operating systems will have many unnecessary services and apps that increase the attack surface of your VMs. If you can’t tell which ones to disable, consult with a virtualization specialist.

Pay attention to physical security

Breaking into a server room is the easiest way to compromise hypervisors, so make sure your physical servers are behind locked doors and watched over by staff at all times.

Install top-notch network security tools

Due to network intrusions affecting hypervisor security, installing cutting-edge firewalls and intrusion prevention systems is highly recommended. These security tools monitor network traffic for abnormal behavior to protect you from the newest exploits.

Stay on top of hypervisor updates

Hypervisors must be updated to defend them against the latest threats. But if you’d rather spend your time on more important projects, you can always entrust the security of your hypervisors to a highly experienced and certified managed services provider, like us.

The recent global outbreak of ransomware attacks such as WannaCry and Petya has made Microsoft sit up and pay attention to the need for better security features for Windows 10. Here are some of the new ones Microsoft has come up with to help keep PC users safe.

Controlled Folder Access

This feature allows you to list certain documents and folders as “protected.” Only whitelisted programs can access and edit these folders, while any attempts by malicious apps to change the folders are blocked by Windows Defender.

In theory, this should slow down a ransomware’s ability to encrypt critical information. Some reports suggest that this feature can also prevent other threats like malicious file macros and viruses.

You can access the feature by going to Windows Defender Security Center and then enabling “Controlled folder access.” From there, you can choose which folders will be protected and what apps are allowed to access them. To save you time, common Microsoft applications are trusted automatically, but you can remove them from your whitelist whenever you want.

Application Guard

Windows Defender Application Guard is designed to prevent intrusions by using Microsoft’s Hyper-V virtual machine technology to detect and isolate compromised applications from the rest of your system. So if someone on your staff accidentally downloads a virus from their web browser, Application Guard will contain the threat before it infiltrates the rest of your company’s devices, apps, data, and network.

Device Guard

Similarly, Windows 10’s Device Guard feature, which is also found in Windows Defender Security Center, minimizes your PC’s exposure to malware by using advanced threat detection policies. It blocks all apps that are not considered to be trusted, ensuring that only approved code is running throughout the system. It also adds an extra layer of defense between your firewall and antivirus software.
