On 6/16/23 I was unable to open my preferred browser on my laptop computer. I tried various methods but unable to resolve the issue. I phoned someone who represented himself as a Microsoft tech asking for advice. He offered to fix my computer remotely (with my permission to get into the computer). He removed malware but insisted that to maintain my computer's performance he would have to install a security program. (Windows 10 already has built-in security). I was reluctant but eventually he convinced me to let him install it – promising that that first year's charge would be waived. I reluctantly input my credit card info. But later found that I was charged $289.95 and the company is in Bulgaria. The tech was a Waredot representative. He refused refund my money even after I uninstalled Waredot.
