A clean install erases files from your mac, but a reinstall does not delete anything. Hence, we are going to outline a way of reinstalling High Sierra MacOS without formatting or erasing your mac. The obvious benefit of this approach is that it preserves apps, files, data, documents, customizations, and photos.

You can try Internet Recovery, but it only works on 2012 and later, or 2010, 2011 models that you installed the firmware update to use Internet Recovery.
On restart, hold down cmd-option-shift-R. If your Mac supports it, you will see a spinning Globe instead of an Apple. It will boot from Apple's servers and will install the OS that shipped on that Mac. However, it had Snow Leopard at best, so I think it will install Lion.
You will need to erase the drive and reinstall OS X. There is no way to go backwards without erasing the drive. Did you make a backup before upgrading? If so, just boot into Recovery and Restore from a Time Machine backup.

How to remove 'Your MacOS 10.13 High Sierra is infected with 3 viruses!' from Mac?
What is 'Your MacOS 10.13 High Sierra is infected with 3 viruses!'?
'Your MacOS 10.13 High Sierra is infected with 3 viruses!' is one of many fake virus alert messages. It targets MacOS users only and is displayed on untrustworthy, deceptive web pages. Typically, users arrive at these sites inadvertently - they are forced to visit them by potentially unwanted applications (PUAs) that users often install inadvertently. Once installed, PUAs cause unwanted redirects to deceptive websites, feed users with various ads, and gather data relating to browsing activity.
Scammers behind the 'Your MacOS 10.13 High Sierra is infected with 3 viruses!' fake virus alert claim to be Apple support team members and state that their website has detected a trojan virus (e.tre456_worm_osx) on your Mac computer. According to this alert, as well as the trojan, three other virus infections have been detected: two malware infections and one spyware/phishing infection. Scammers urge users to take immediate action and remove the detected viruses to prevent system damage and data loss. They give users five minutes. Note that Apple has nothing to do with this scam. Cyber criminals use the company name to promote their fake product, which they state will remove viruses and prevent any further damage. In this case, they promote the Mac Cleanup Pro application. When installed, this app will detect even more infections and other problems on a Mac computer, however. This is simply a way to trick people into purchasing this product by displaying fake results. The scan itself is free, but removal of detected issues must be purchased. Never trust scammers or purchase/use their apps. We recommend that you ignore 'Your MacOS 10.13 High Sierra is infected with 3 viruses!' simply by closing the browser window or tab. If this deceptive website prevents you from closing the window/tab, use Activity Monitor to force-quit the browser. Do not restore the closed session, since this will reopen the same deceptive website (or another site that led you there).
Users commonly arrive at these websites due to installation of potentially unwanted apps. These PUAs cause redirects to deceptive websites, deliver intrusive ads, and gather data. They display coupons, banners, surveys, pop-ups, and so on. They are displayed via tools that enable placement of third party graphical content on any site and also conceal underlying content. They affect browsing quality and, if clicked, lead to untrustworthy websites or run scripts designed to download other unwanted apps. Furthermore, PUAs record browsing-related data (such as IP addresses, keystrokes, search queries, URLs of visited websites, etc.) and also personal details. Developers share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue. Thus, having these apps installed can lead to computer infections, privacy/browsing safety problems or even identity theft.

Many similar websites display fake messages and virus/error, and other, alerts. Some examples of other fake messages are Your OS High Sierra Is Infected With (3) Viruses!, Your Computer Was Locked, and Mac OS Support Alert. Scammers often use these fake messages to trick people into believing that their computers are infected or damaged, and to encourage them to purchase unnecessary products or technical support/guidance. Most PUAs are very similar - developers promote them as 'useful tools', however, these are merely attempts to give the impression of legitimacy and to trick users into downloading and installing them. Typically, they deliver none of the functionality promised and are designed only to generate revenue for the developers.
How did potentially unwanted applications install on my computer?
Some potentially unwanted apps are available for download on their official websites, however, many users are tricked into installing them through clicked intrusive advertisements or a deceptive marketing method called 'bundling'. Developers use this method to trick users into installing unwanted applications together with other software. In most cases, PUAs are hidden in 'Custom', 'Advanced' (and other similar) options/settings of the installation/download dialogs. Information regarding the presence of PUAs in the download/installation set-ups is not properly disclosed. Nevertheless, inadvertent installations are usually caused by users who skip installation steps, leave download/installation settings unchanged, and click various ads.
How to avoid installation of potentially unwanted applications?
Careless behaviour and poor knowledge of these threats are the main reasons for problems relating to online safety and privacy. To protect your privacy and keep your computer safe, browse the web and download, install software carefully. Do not download software from unofficial/untrustworthy websites, using third party downloaders/installers, or other such tools. Check all available 'Custom', 'Advanced', and other similar options when installing or downloading software. Many malicious/untrustworthy advertisements lead users to adult dating, pornography, gambling, and other similar untrustworthy websites. If you experience constant redirects to these websites, check all extensions, add-ons, and plug-ins that are installed on your browser and remove any suspicious/unwanted entries immediately.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
