Meanwhile, the candidate who leads the polls for the first round but not for the run-off, far-right leader Marine Le Pen, was stripped of her parliamentary immunity by the European Parliament in a move than is unlikely to impact her image to her voters.
And all opinion polls indicate that the scandal over the terrorist pictures and separate accusations of alleged financial malpractices in her far-right National Front party would make no difference to the lead which she now enjoys in the electoral campaign.
French judges had been investigating le Pen after she tweeted three images of Isis executions in December, including one of the American journalist James Foley who was beheaded by the terror group in Syria.
Fillon announced Wednesday that he would continue his campaign despite allegations that he used public funds to pay his wife to do a fake government job.
A second poll by Opinionway, released daily, shows Macron at 62% against 38% for Le Pen in the second round, which is quite similar to previous days.
Le Pen, whose presidential bid is gaining momentum, dismissed any wrong-doings and described the affair as "a political plot".
There was more bad news for the beleaguered presidential candidate as he campaigned in southern France on Thursday: his Paris home was reportedly raided by police.
Fillon's claim that his campaign was being targeted in order to sink it drew indignation from President Francois Hollande, who said the candidate had no right to "create a climate of mistrust.to throw extremely serious accusations at justice and, more broadly, our institutions".
March on with a hike?
Benchmark Brent crude futures were up 0.7 percent at $55.46 a barrel after closing down 2.3 percent in the previous session. The S&P 500 index showed two new 52-week highs and no new lows, while the Nasdaq recorded 24 new highs and 12 new lows.
He took aim at Fillon's declared admiration for Britain's union-bashing former Prime Minister Margaret Thatcher, and at his plans to cut half a million public sector jobs, saying, "The future of France is not a set of British-style reforms from the '80s". He left that post a year ago to start his En Marche! party, a self-described centrist group.
The top two from the first round proceed to a run-off on May 7, which Macron is now shown winning.
Now that Le Pen has lost immunity, she may face a prison term of up to five years or a fine of 75,000 euros.
According to the latest opinion polls, Le Pen is the front-runner, followed closely behind by the leader of the En Marche!
The always-packed agriculture fair was less kind to Macron, the 39-year-old former French economy minister who got hit on the head with a raw egg.
The lifting of Le Pen's immunity relates to this case only, and any action is unlikely to occur before the first round of voting in the French presidential election on April 23.
"Mr Fillon is now the third man", he wrote.
"Everywhere, from Donald Trump's America, to Narendra Modi's India, from Xi Jinping's China to Theresa May's United Kingdom, economic patriotism is prevailing", she said.
