If you are unsure of the source or provenance of a message or alert, do not respond to, or engage with, the message. Certainly do not, under any circumstances, attempt to contact anyone using the contact details that may have been provided within the message itself. If you need to verify a message from Apple, make independent contact with Apple Support.
Most scam alerts are designed to scare the unwary into giving away sensitive information - or to fool you into doing something that you shouldn’t - usually to defraud you financially.
There are no true Antivirus Products available for iOS/iPadOS. Those that claim to provide AV protection are little more than “snake oil” - and should generally be avoided. Many are simply a vector to install software that may actually try to cause harm to your data, or perpetuate a scam.
Providing that your iPad has been kept up-to-date with system software updates, you should not be overly concerned for your iPad being directly compromised by malware. Due to the system architecture of iOS/iPadOS, unless jailbroken, your iPad is not susceptible to traditional malware infection per-se. However, as with all computer systems, there are still vulnerabilities and exploits to which you remain vulnerable. For older devices, no longer benefiting from regular security updates, the risk of an unpatched vulnerability being exploited increases.
Regardless of the installed version of iPadOS, there are useful mitigations that can be used to significantly reduce your exposure to risk...
Threat Mitigation
The majority of threats to which you will be invariably exposed will surface via web pages or embedded links within email or other messaging platforms. Browser-based attacks can be largely and successfully mitigated by installing a good Content and Ad-blocking product. One of the most respected within the Apple App Store - designed explicitly for iPad, iPhone and Mac - is 1Blocker for Safari.

1Blocker is highly configurable - and crucially does not rely upon an external proxy-service of dubious provenance, often utilised by so-called AntiVirus products intended for iOS/iPadOS. Instead, all processing by 1Blocker takes place on your device - and contrary to expectations, Safari will run faster and more efficiently.
Unwanted content is not simply filtered after download (a technique used by basic/inferior products), but instead undesirable embedded content is blocked from download. The 1Blocker product has also introduced new “Firewall” functions - that are explicitly designed to block “trackers”. Being implemented at the network-layer, this additional protection works across all Apps. 1Blocker is continually updated by its Developers - and has introduced additional network extensions, extending protection to other Apps.
A further technique to improve protection from exploits is to use a security focussed DNS Service in preference to automatic DNS settings. This can either be set on a per-device basis in Settings, set-up on your home Router, or both. Using this measure with your Router extends benefit of this specific protection to other devices on your local network. I suggest using one of the following DNS services - for which IPv4 and IPv6 server addresses are listed:
Quad9 (highly recommended)
9.9.9.9
149.112.112.112
2620:fe::fe
2620:fe::9
OpenDNS
208.67.222.222
208.67.220.220
2620:119:35::35
2620:119:53::53
Cloudflare
1.1.1.1
1.0.0.1
2606:4700:4700::1111
2606:4700:4700::1001
Use of the above DNS services will help to shield you from “known bad” websites and URLs - and when used alongside 1Blocker, or other reputable Content Blocker, provides defence in depth.
There are advanced techniques to further “harden” iOS/iPadOS (such as using DoH, DoT and DNSSEC). Apple has introduced its Private Relay service to its iCloud+ subscribers - in part employing ODoH (a variant of DoH) as an element of this functionality. If you have subscribed to iCloud+, and have a device capable of running iOS/iPadOS 15.x or later, this feature is included.
DoH and DoT are natively supported by iOS/iPadOS, but are not exposed via iPad settings; to directly configure and use these protocols you will need to use a third-party App - such as DNSecure. ODoH is also natively supported - but is only available to iCloud+ subscribers using Apple's Private Relay function.
