They are perceived by a very small minority of Jews and Christians as unbelievers and as their enemies although the vast majority of educated Jews and Christians will simply view them as fellow humans worshipping the same God according to their own beliefs and traditions.

Answer 2
The Jewish perception of Muslims depends on whether you are asking from a religious perspective or a political perspective. Religiously, Jews accept that Islam is a valid religion for non-Jewish people and the famous Rabbi Moses Maimonides (Rambam) said over 900 years ago that Islam was part of the Divine Plan to make Knowledge of God a worldwide phenomenon. Jews support Muslims' right to pray and see their rituals and ceremonies as valid and proper, just not for Jews (who are obligated to follow Jewish Law).
Politically, Jews and Muslims have a number of unresolved issues. During Mohammed's life and the Caliphate period, Jews saw Muslims as preferable overlords than the Christians since Muslims permitted Jewish practice whereas Christians often did not. However, this tolerance is viewed by Muslims as being peaceful and harmonious, whereas Jews see it as a second-class citizenship. Additionally, Muslims circulated numerous Anti-Semitic hadiths and, in the modern period, embraced many Anti-Semitic books and pamphlets from Europe. Jews are immensely bothered and angered by the positive reception that many Muslims gave such derisive nonsense. Most recently, the united Islamic opposition to the State of Israel and its internationally confirmed Right to Exist infuriates Jews because Muslim politicians continually try to deny both the political validity of Israel as well as the religious connection that Jews have to the land. The Jewish perception is that these Muslim leaders and many Muslims in Muslim-majority countries are unwilling to even consider the Israeli or Jewish points of view while demanding that their political will be enacted.
