How to remove virus? Run a virus scan first

Before cleaning your Windows PC of viruses, you have to scan it first.

Here is how to do this:

1. If you have non-Kaspersky security software installed, run a virus scan on your PC using Free Kaspersky Virus Removal Tool. See instructions.
2. If you have Kaspersky security software installed:

• Check that the “Detection of software that can be used by criminals” in our product settings is enabled.
• Update product's databases.
• Run a Full Scan. Once the scan is complete, remove any threats or malware found. If you are prompted to perform a treatment with a restart, select this option.

How to preventing infection?

Here are some basic ways how you can protect your computer from viruses:

• Use an antivirus software for malware protection. For example, Kaspersky Premium (free trial available).
• Download applications and software only from trusted websites.
• Never click on any untrusted links in spam messages, emails, or unfamiliar websites.
• Don't open attachments in spam emails.
• Keep your anti-virus up to date and keep your installed applications and operating system up to date.
• When using public Wi-Fi networks, use a secure VPN connection such as  Kaspersky VPN Secure Connection (free version available).
• Never connect unknown USB sticks to your computer or insert unknown drives.
