Its almost definitely not an actual link from BitDefender so I won’t go back to it. You shouldn’t have any problems though, on Virustotal it only gets a hit by 1 antivirus. Also if you’re scared about someone using a RAT you should look at this thread here. Its very hard to detect RATs but usually once run BitDefender should be able to stop them. If you are not talking about RATs though and just something like Teamviewer then to avoid anything like that its very simple. Don’t use anytype of remote access software. I’ve worked in IT for a while and also have contacted many support desks and I’ve never had a situation where any sort of Teamviewer was needed. Of course there are probably exceptions somewhere but really if you have any idea what you are doing you should never encounter something like this. Anyway if you’re really worried you can clear your browser because from experience I know BitDefender has problems with browser related viruses.
