Coronavirus and ibuprofen: Separating fact from fiction
https://www.bbc.com/news/51929628

The NHS website previously recommended both paracetamol and ibuprofen, but has since changed its advice to say that while "there is currently no strong evidence that ibuprofen can make coronavirus (Covid-19) worse... until we have more information, take paracetamol to treat the symptoms of coronavirus, unless your doctor has told you paracetamol is not suitable for you."

There has been no research into ibuprofen and the new coronavirus (Covid-19).
But there has been some for other respiratory infections, suggesting ibuprofen is linked to more complications and more severe illness - although we don't know that the ibuprofen itself is causing this, according to Paul Little, a professor of primary care research at University of Southampton.
Some experts believe that ibuprofen's anti-inflammatory properties may affect the body's immune response.
Prof Parastou Donyai at the University of Reading says: "There are many studies that suggest ibuprofen use during a respiratory infection can result in worsening of the disease or other complications."

As a summary, it's more or less a conspiracy theory. Nonetheless, don't take ibuprofen unless your doctor tells you so.
