Customer Testimonials

FAQs

Antivirus typically refers to software that has been created to find, destroy, and prevent computer viruses. Antivirus software usually runs in the background while the computer is on.

There are certain telltale signs that can indicate that your device is infected with a virus. Some signs to look out for are:

  • Missing or changed files and folders.
  • Slow device performance.
  • Frequent and unexpected pop-up windows.
  • Unrecognized programs.
  • Issues with restarting and shutting down.
  • Device crashes often.

If you suspect that your device has a virus, it’s crucial that you use antivirus software to run a scan on your system.

If you are looking for an antivirus program for your Mac, you will need to search for programs that are specifically designed for macOS. This is because Windows and macOS are separate operating systems.

Currently, iolo’s antivirus program is only available for Windows 11, 10, 8.1, 8, and 7.

Antivirus software is used to scan systems for viruses, worms, and other types of malware, removing or isolating these threats. Meanwhile, antispyware specifically looks for traces of spyware and adware, mostly scanning for internet threats and eliminating them if found.

In essence, an antivirus program detects threats (including all types of malware) in files and folders, whereas antispyware programs detect and destroy threats related to online activity and personal information. Both have a similar goal of protecting your information.

Yes. It’s important to make sure that your antivirus software is regularly updated according to new updates released by the manufacturer. While some antivirus programs can update automatically, it’s still key to check that your antivirus software is up to date. This ensures that your virus protection level is at its highest.

Failing to update your antivirus software can result in features that don’t function properly, lowering your computer’s level of security.

If a virus is detected on your computer, you will be notified, and the antivirus software will work to kill the virus before it can harm your system. Antivirus programs have been made to identify common malware, so there’s no cause for concern as long as your antivirus software is updated and from a reputable company like iolo.

This virus will be eliminated and prevented from attempting an attack on your system again.

Anything that is writable and connected to your computer can be infected with a virus – this includes USB thumb drives. A malicious file could be downloaded onto the USB thumb drive, and when inserted into your computer, this can spread to your system.

Antivirus software should be able to detect and block this from happening.

Yes. Two antivirus programs cannot co-exist within the same system. It’s important that you uninstall your old antivirus software before installing a new one to ensure maximum efficiency and security for your computer.

Free antivirus software exists; however, these can be risky to use, especially if you are downloading them from unknown websites. Please be careful of downloading programs onto your computer, as these ‘free antivirus software’ solutions could potentially be malware.

To be safe, it’s recommended that you purchase legitimate antivirus protection solutions like iolo’s System Shield, System Mechanic Pro, or System Mechanic Ultimate Defense.
