Hi Cornelia,

Here is the list of top anti-virus solution you can use to protect your laptop.

Bitdefender Antivirus Plus 2019 is in first place of a crowded market at the moment. It's easy to use, priced brilliantly (no more than around $2/£2 per month) and, crucially, is a fantastic first line of defence against cyber threats.

For the stated price, you get more than you ask for in terms of features. First of all, Bitdefender is well-known for its reliability in terms of zeroing in on any potential threat to your PC. It is armed with robust web filters that prevent access to suspicious websites, while its secure browser will make any web shopper sigh with relief knowing that transactions can now be completed without malicious interference.

Kaspersky Antivirus 2018

Kaspersky Anti-Virus 2018 is like a comeback album from a band discovering its roots with superb results. Back to basics for this antivirus service means excelling at the essential security tasks. Now, you can say that web and URL filtering, ever-watchful and reliable antivirus engine and intelligent behavior monitoring of malicious codes are typical today, but Kaspersky Anti-Virus shows its mettle by giving you the best performance in these segments.
Efficiency is paired with accessibility here, as its interface strikes just the right balance between being rich enough in options without unnecessary clutter. Delivering sophistication in simplicity is a mission statement Kaspersky manages to put into practice with panache.

AVG AntiVirus Free
Yes, AVG AntiVirus plays with your expectations by giving you perfectly capable antivirus features, yet with the missing info under the pricing section.
The package (expectedly) comes with antivirus engine, real-time email and download scanning, as well as a powerful web filter. Yes, you read it right, the same basic features offered by its commercial competitors. There is no catch here, no advertising scheme or restrictions that would force you to buy its paid version, it is a genuine no-strings-attached arrangement this time.
Those who want to go ahead with the commercial version for any reason will be given access to additional features related to online payments, privacy and anti-hacker protection. For many, the paying edition will hardly justify its relatively high price (£49.99 or $70 for a year) particularly when the free edition is this good.
It will give you six types of scan, including a deep system scan and USB/DVD scans which will all be performed at rather high speeds. As a bonus feature, AVG AntiVirus offers file shredder and a built-in browser add-on scanner. Speaking of scanning engine, AVG’s product offers not good but great detection rates which, in some test, leave even its pricey competitors in the dust.

I hope this helps.

Regards,
Lokesh
